    Since the subject of disinfectants has come up, let's address it on a more practical level under two assumptions:

    1. This virus is going to be with us for a while, and it is some time before effective medication or vaccine will be available.
    2. Some institutions are going to reopen before effective treatment or vaccines are available.

    How do we keep multiple users of pianos in studios from spreading the infection by way of the piano?

    I was approached by a teacher at a conservatory who expects to be called back to work sometime in the near future and assumes that she should be disincfecting the piano between students. She asked how she could do this without damaging the piano or perhaps (mildly) poisoning the students.

    I have my own thoughts on the subject, but I just wanted to throw the question out to hear what others have to say 

    Thank you,

    As I recall Mario Igrec posted a mix his staff had been using at Juilliard (Fantastic mixed with something else). That said, mixing cleaning chemicals can result in poisonous gases, so it is not the time to randomly experiment at this!

    Small practice rooms seem problematic to me, but I mostly have a suburban clientele. And lockdown until at least May 18.

    Thanks, Patrick

    Found Mario's post, here's the mixture:

    We've been using a mix of 40% fantastik, 40% water, and 20% alcohol (91% isopropyl) on plastic/ebony keys. We use this for poly and lacquer finished too.

    Seems pretty benign...

    Hi-

    Not to dispute other formulas but we simply use hydrogen peroxide straight out of the bottles, a 3% solution. It's cheap, easy, and works.  I've read that hydrogen peroxide takes about 1 minute of exposure to kill germs or virus, but is not at all harmful to finishes or plastic-as opposed to alcohol. 

    Best,
    Dennis.

    In the meantime I learned that there are several types of Fantastik product. The one that is approved by epa for SARS-CoV-2, the virus that causes COVID-19, has "disinfectant" in the tag line under "Fantastik":

    https://www.whatsinsidescjohnson.com/us/en/brands/fantastik/fantastik--Disinfectant-Multi-Purpose-Cleaner--Fresh


    The epa list is here:

    https://www.epa.gov/pesticide-registration/list-n-disinfectants-use-against-sars-cov-2

    If you look up Fantastik, you will see that it is listed as requiring 5 minutes to kill the virus. I guess that is without manipulation, and when we rub the keys its effectiveness should be sped up greatly.

    To increase its disinfecting properties, I have mixed Fantastik with more alcohol and no water (60% fantastik + 40% concentrated isopropyl [91% or stronger]) and have had good results on the keys and on lacquer and poly finished. No apparent combustible reactions or deadly fumes. The mix flashes off rapidly, degreases better than anything else I've tried, and leaves no visible residue. But do I need to soak the keys for 5 minutes? I don't know, but the mix evaporates way faster than that.


    I have to say that my techs and I get a mild headache from Fantastik by itself or mixed with alcohol. It's clearly not something we'd prefer to work with continuously. When we get back to work, the first thing I'll try is the pharmacy (3%) hydrogen peroxide, but I remember from years ago that spraying it caused visible changes on the fallboard finish. That may have been because of the dirt or inferior finishing product on the fallboard. At Juilliard we have pianos that were refinished (or finish reflowed?) with a product that gets damaged by alcohol whereas factory lacquer doesn't. It may be the same with hydrogen peroxide. 


    The other strategy I would've pursued before the school shut down was giving students alcohol pads such as Purell hand wipes so each user can disinfect the keyboard before use. What good is daily disinfection if 10 or 20 people will use the piano during the day? Unfortunately, we couldn't procure enough of those to have made them a feasible strategy. Now I hear from more people that Clorox wipes are OK, and will look into those. But I remember having a skin reaction and headache with those and Lysol wipes. 

    Someone asked, what about ivory. For an occasional cleaning of very dirty keys I've used alcohol or the Fantastik mix. Keybrite is very nice but slower. I've also used water with a little dish soap, which is even slower. I think alcohol or strong cleaning agents are not good for ivory in the long term.

    In all the sources I have read, soap and water top alcohol and other disinfectants in both effectiveness and speed. So why not just use soap and water?

    Ozium-Air-Freshener-Sanitizer would be another thing to consider, in addition to other the things. I could see that being effective in a practice room. It's main thing is to get rid of odors but it accomplishes it by killing airborne bacteria & germs. Just a thought...

    Soap and water on hands is being rinsed with a lot of water. Viruses are detached from surface and flushed. I am not sure they are necessarily killed. It's different on the keys.

    What I am not clear about is does the degreasing effectiveness and speed indicate how effective a product is on the virus? Apparently there are disinfecting ingredients such as quarternary ammonium. How is their effect different from degreasing products, which remove the fatty shield and kill the virus that way?

    Much more to study.

    Soap and water actually causes viruses to come apart. Google it. Reams of articles explaining the mechanism. Here is a good sample NYTimes article on the subject. Here is a Twitter thread written by an expert in supramolecular chemistry - don't be put off by the fact it is on Twitter, read it. Soap is simply particularly good at breaking down the structure of viruses.

    If you want a comprehensive list of disinfectants from CDC, here is a list of over 400. Note the disinfecting time column - in minutes. Some are as short as one minute, most list at 5 - 10 minutes. Note also that soap takes 20 seconds.

    I think this is much like the anti-bacterial soap thing: people want something more complicated, more "chemical." Soap is, in fact, a very potent and elegant chemical, that works wonders. The fact that it is so common and every day makes us ask for something else. The anti-bacterial additives do nothing to enhance the action of soap, as has been demonstrated and written about repeatedly, but people still buy it.

    About soap and water:

    I carefully read the New York Times article, and looked over the Twiter thread on the subject, and yes, soap and water appear to be very effective for personal hygiene and protection from viruses on a personal level. But this is not the subject of this thread.

    From what I see in the Times article, soap is effective in combination with water when leathered up, "worked" for at least 30 seconds and then rinsed off. The mechanism in the soap/water combination that effectively destroys viruses is contingent on this procedure. If every piano user did that before and after using the piano, we would have a lesser problem. But they don't, and there is no way we could make sure that they do. 

    We are dealing with a totally different problem here: preventing transmission of viruses that might have made their way onto pianos by way of hands of users who did not follow proper hygeienic procedure, or from the breath, coughs, sneezes of users who may be asymptomatic infected persons. Soap-and-water on keyboards and pianos, well-lathered up and scrubbed for 30+ seconds then rinsed off between users just isn't an option. Nothing in the article or the Twitter thread suggest that just soap by itself might be effective,

    So we are back to various disinfecting strategies.

    Scrubbing and lathering are specially necessary for hands, due to the wrinkles and crevices, hairs, pores, etc. in skin. For any surface, the effect of soap requires that the virus be surrounded in order for the "soap nano-particles" to do their work. Yes, the surface should be wetted with a soap solution and "agitated/scrubbed" a bit. Dirt on the surfaces should be removed, as it provides a place for viruses to lurk. That is particularly true of the sides of sharps (sides of naturals as well, to the depth of key dip).

    How are other disinfecting strategies any more practical? We have these notions of the convenient and perfect spray/fog or radiation of some sort. None of them is likely to be possible in any practical way, certainly not doable between each piano user.

    The bottom line is that what we imagine we should do is simply impossible. Shared pianos cannot be guaranteed virus free (unless given something like 4-5 days between users). We need to resign ourselves to this fact. 

    There are things we can do to improve the situation somewhat, and we should focus on that. From all I have read (and I have read a lot), soap and water are top, #1. The focus of articles tends to be on hands, and for good reason, but there isn't anything about hands that make them a special surface when it comes to viruses, except that skin is a wrinkled surface, so a bit more challenging.

    I am not dealing with disinfecting keyboards and pianos in practice rooms for days and weeks. I am trying to find some advice for a teacher at a conservatory who has to sit in a piano studio for several hours at a time with students, who asked me what she could do to minimize the possibility of students transmitting infection to each other - or to her - by way of the piano on which she teaches. So, with that in mind, how about not dismissing various proposed remedies? Scrubbing with soap and water between lessons is not an option, OK?

    Israel, I assume the small studio has no window for fresh air? My recommendation would be to declare a sabbatical for herself. Offer to teach online. Be prepared to be fired if that's the administration stance. Shelter in place. That's from the perspective of Hot Spot Massachusetts. Your nation probably has a better handle on the situation than we have in the US these days.

    Israel,
    What is possible is to clean the keyboard and other surfaces throughly as a starting point. Then your teacher needs to institute a strict hand-washing regimen plus mask and general distancing protocol: go with each student to the sink and observe hand-washing before giving a lesson. 

    That is practical advice. I doubt you will find anything better, with the given of spending time in the studio with the students.

    My wife is teaching via Skype/FaceTime/Zoom. That is a more effective solution from the point of view of disease prevention.

    OK, let's start from the beginning. All this teacher wants to know is what to suggest to the management of this institution in terms of purchasing supplies for the instructors to use in mitigating transmission of virus from student to student via the piano once they decide to reopen. Taking a "sabbatical" is not an option once they reopen, if she wants to keep the position, where she is finding work is pretty tough.  I can't see all the instructors trooping to the bathroom with their students before and after lessons to watch them washing their hands - this is not a private studio, it's a school, so therefore some "disinfection" between lessons is deemed a good idea. Also, I don't know how kindly older or adult students might take to a female teacher following them to a men's room and vice versa - never mind those using the facilities for their primary purposes. We all know about masks here - they have been mandatory whenever one is outside the home for the past month, and every supermarket is selling disposable ones by the boxful, plus a whole bunch of enterpreneurs are getting into "fashion designer masks". (Not that everyone is following the mandate, but there is a fine, technically - not being very well enforced...) Thank you for all your suggestions.

    Hi,
    I work at Western Michigan University an all Steinway School and have researched this and Have had many years experience with this mostly cleaning up instruments that were infected with mice or bat feces.  First check the ptg.org/covid-19 page.  
    Disinfectants will work best if the surfaces are clean first because they work by breaking up oil/fat. The less grime and oil on surfaces let the disinfectant work on disinfecting.  It's best to clean keys first (paying extra attention to the sides of keys) by using a damp cloth with soap (hand or dish).  Once this initial cleaning  is done use 70% rubbing alcohol preferred, or alcohol wipes(having no other chemicals) or hand sanitizer on the keys (test first).  The alcohol should work for two minutes. Let dry.  Don't use a rag, use shop towels or paper towels and dispose of.  

    I think the keys and case parts around the piano's music desk should be cleaned the same way between students.   Remember that students are handling their music as they play so this cleaning has to be done between students.  Test the wipes on the case (upper, inside leg area would be a good place).  Alcohol wipes would be handiest.  

    Maybe the teacher should have the students commit to hand washing before and after the lesson by signing an agreement along with if they are sick that they will reschedule their lesson And whatever other rules they have for their studio.  Hand washing has to be practiced for the disinfecting to work without cleaning in between students. 

    I would recommend having hand sanitizer 70% alcohol or more and have the student use before and after lesson.  Remember that the virus can be in the air up to 3 hours after room use. Masks need to be worn.  

    My experience and research tells me that other chemical disinfectants are corrosive and are not safe around piano wire, key pins and your tools.  From testing generic disinfecting wipes with ammonium chloride on some pianos it seems safe on some plastic key tops and some cases short term.  I don't recommend these products because they are corrosive.  

    For more information on disinfectants and covid-19  this is a very good site:

    There is a tab in the 1st paragraph of the article on all sorts of disinfectants approved by the CDC to fight covid-19.  Search disinfecting vs.  sanitizer and you will find that alcohol is a disinfectant.  All of the products need to be on the surface for a duration of time to be effective.  A disinfectant is not a cleaner it is used to kill bacteria and viruses and soap should be used to clean, this is the first step.  

    How in they world are wind teachers going to get back to one on ones with all those water droplets going all over?  I think in some way pianists might be a bit luckier in this situation but there are still some risks.

    Hi-

    The more efforts we have working together in this battle the better. I agree you can't expect the instructor to follow each student to the sink and observe hand washing before a lesson, unless perhaps they are small children.  The vast majority of adult students will respond and cooperate with such a policy and a sign should be up on the door announcing hands must be freshly washed before each lesson.  That, in addition to a quick wipe down of the keys between lessons, wearing masks, and no sharing of pencils or music as mentioned earlier, will all significantly reduce the risk of spread. That's the best we can do.  I think I will recommend a policy like that for our department also.  We already have hand washing signs up around the building elsewhere and people are beginning to expect that. Our President has already announced that when we do go back to work all employees will be expected to wear masks.

    Israel,
    The honor system is an alternative to following them into a restroom. Simply make it clear to all students that they must wash their hands just before entering the studio. Ask them each time. Annoying, but effective. My wife has done that with all her students for decades. (She has the advantage of a teaching studio with its own bathroom).

    In a situation like a teaching studio, where the faculty member has a degree of control of who enters, this is feasible. In a practice room area, it is necessary to develop a culture where hand-washing and mask wearing is simply a given.

    Responsible behavior by humans, what a concept!

    Not infallible, but it is probably the best we've got. I am certainly open to other ideas, if any truly practical and effective ones are presented. I've been paying attention, but haven't seen any yet.

    There is a saying that is ignored at one's peril: don't let the perfect stand in the way of the good. No procedure, substance or behavior is going to guarantee 100% protection from infection. Some are better than others, and in all cases a combination of several may increase overall effectiveness - if only marginally. If a quick wipe of the keyboard with some disinfectant substance can add maybe 10% effectiveness to all the other precautions - then why not do it? There is no magic bullet, and there is no use pretending that any of the ideas offered will by themselves offer maximuim effectiveness. Which is why I bristle at the suggestion that just because A is not as effective as B, is a reason to dismiss A altogether. Students may forget about hand washing, instructors who are not used to it may forget to ask, after the first few weeks people tend to get sloppy about things, so a quick wipe of the keyboard with a disinfectant may be a backstop which just might be that bit of redundancy that might prevent a case or two of infection. You know the one about putting all your eggs in one basket? Enough said...

    In two-piano teaching studios, consider a plexiglas shield between teacher and student pianos.

    For practice rooms, perhaps students could be given a shop towel in a plastic bag, wet with rubbing alcohol. They could be instructed to wipe the keyboard before and after practice, and to wipe door handles when they enter and leave.

    At our college, our piano teacher had a giant bottle of 70% alcohol Purell gel on his desk by the door. Students were instructed to wash hands before and after lessons, but they also had to smear their hands with a full pump as they walked in the room and were allowed to do the same as they leave. (Past tense because we are still shut down.)

    <sarcasm>
    Since our students avoid practicing in general, this is just one more excuse, so there is no need to sanitize our practice room pianos since they aren't being used.

    My wife is a nurse & handwasher extraordinaire, most of the time she has raw knuckles from her constant washing. Her one complaint has been the antibacterial soaps! Soap is all you need if you wash properly, the antibacterial stuff gets into the ground water & helps the antibiotic resistant germs develop. 
    I have been using the disposable wipes for myself/customers safety. I wear disposable gloves wipe the piano down, keys, most-touched areas.

    For simple cleaning and degreasing I've found that a small amount of toothpaste on a slightly damp towel does just fine. The keys can then be wiped by another barely damp towel to take off any residue.

    No headache, no toxicity at all.

    If one then wished to sanitize, wiping with 60% ethanol seems like it would work. If students wished to sanitize before they practiced, a lidded plastic bin with a fairly damp but not soppy wet towel in it (60% ethanol) could be left in the room, and renewed a few times a day. So long as the towel was still damp with ethanol, it wouldn't get contaminated.

    I recently purchased a UV-C light wand made by Verilux. UV-C will instantly kill all bacteria and virus on any smooth 
    surface. UV-C is use in hospitals and many other settings as a powerful disinfectant, and there are no liquids or odors involved. I highly recommend it for use on piano keyboards, stretchers, etc., both before and after tuning.

    Paul, 15-20 seconds of exposure needed. How much area does it cover in each 15-20 seconds?

    Hello Larry. 
    I haven't heard that figure in terms of exposure. The directions ask you to move slowly and a 1/2" or less from the surface. 
    I did do some research prior to using this product. I would appreciate it if you would forward any information that could provide additional insight. 
    Paul.

    This is cool. Our facilities manager is looking into getting one of these. 

     

    So it doesn't harm ivories?  We only have 2 or 3 with them.

     

    Thanks

    Paul

    For some years now I've been using Windex wipes with good success on keys and case parts

    .It has a combination of detergents,non ionic surfactants and ammonium hydroxide (ammonia water) and as Mr.Sturm points out soap and water kill this bug. The white cloths let you know how much stuff is still coming off with each pass.

    In more advanced filth you might want something stronger.

    Moldex has Alkyl Dimethyl Benzyl Ammonium Chloride (or quats) and kills nasty stuff very well. It will however leave a visible film on a high polish finish. Hence the Windex surface cleaner. The blue towels are available at your big box home repair store and are more durable than the home use ones.

    As has been mentioned in a related thread, vocal studio (chorus/choir) pianos are particularly vile. Lots of dried saliva. Be prepared to be horrified.

    FWIW I spend about 30 - 45 minutes cleaning the high touch surfaces of a piano that hasn't been cleaned regularly. The sides of the sharps are where you find the real dirt. YMMV.
    Wear gloves and a mask. Be smart. Be safe.

    I have a follow up question about Fantastik and Windex. I was told years ago by two separate band/orchestra/fretted instrument repair techs to never use ammonia on any plastic or ivory (or vinyl) because it did something to make them "brittle" and they would eventually crack. They claimed this is why old piano keys are filled with cracks, because people cleaned them with ammonia based cleaners. They also blamed this for plastic clarinets splitting and interior car vinyl cracking. Does anyone know if this is true? If so, Windex and Fantastik are bad ideas in the long run. The only thing I've ever used (until now) to clean keys is water, light soap and water, or eyeglass (or plastic keyboard) cleaner like the kind you get from Cory products or from eyeglass centers. Recently, I've reluctantly put a little 91% alcohol on a rag and cleaned keys with that, but I knew ahead of time it would take the paint off old, painted black keys (yes, it really does, but so can soap and water) so was careful about that. Unless someone comes up with new info, I'm sticking with my alcohol or soap and water. I'm too afraid to use anything else. (Clorox wipes are basically the same thing as fantastik & windex wipes.) That and constant washing hands & using hand sanitizer (I just spray my hands with my 91% alcohol) is all I'm doing. I'm not working much these days, anyway.

    Israel - I posted above what our college piano teacher is doing. I hope that helps a little. Good luck.

    I happened to read this article prior to purchasing the Verilux Sanitizing Wand, Ed. When placed into the context of all the other information I saw online about UV-C, I found this piece to be a needlessly inflammatory outlier. This guy makes pretty reckless and generalized statements about the use of UV-C that don’t apply at all to this new type of small-scale consumer product powered by nothing more than a few AA batteries.
    Yes, there are real dangers to using UV-C if employed improperly and at relatively high levels of radiation, but I’ve found the Verilux light to be completely safe and easy to use when certain simple precautions are taken.
    I’m not an expert on the subject, Ed, but I think in the coming months we will see a lot more information coming out on how to best incorporate UV-C technology into our arsenal of weapons for fighting this virus.
    We should all stay tuned.....

    My concern is to question the efficacy of these devices. Most of the material that comes up via Google seems to be self-certifying articles.
    I can't find real testing of these little wand devices. What is their real effectiveness? How do you use them over extended areas like keyboards? How do you clean the area between the keys? What is their effective range and area of coverage?
    Some information may be gleaned in this article, but it is probably based on manufacturer self-reporting.
