Cleaner for NY Stwy high gloss lacquer finish?

  • 1.  Cleaner for NY Stwy high gloss lacquer finish?

    Posted 16 days ago

    Greetings,

    Got a 1989 NY Steinway with a high-gloss lacquer finish. HIgh-gloss polyester cleaner doesn't work. Neither does "Satin Finish Cleaner." (Or, for that matter, Fantastik or isopropyl.)

    This is the only piano I have come across with this type of finish. Anyone able to advise, based on their own experience or that of a known-to-be-reliable source, what cleaning substance will get the job done on this stuff?

    TIA,

    Alan

    Editing cause I see you said lacquer.  (Jescar paint refresh for polyester finish)

    To the extent this is original, I believe this finish was achieved with polishing techniques and must be maintained using those same techniques. In other words, there isn’t a product that will restore it

    I wish I knew what those techniques were but I’m ignorant of them.

    You could always convert to satin lacquer

    Thanks for your input, Daniel!.

    It's the original finish, all right. This piano was purchased new at my school and has not been refinished. I am only surmising that it is lacquer, because all the many edges that have had the finish rubbed off.

    Beat,

    Alan

    Hi, Alan,

    It was French polish carried to a ludicrous extreme that was available as an option off and on for some years. If memory serves, the lacquer used during that period was mostly automotive “quality” (meaning a higher volume of solids). Eminently repairable; but insanely time consuming. Beautiful; and difficult to properly maintain.

    Sorry for your burden around that.

    Kind regards.

    Horace

    Hi, Alan,

    You are most welcome!

    After I pushed “send”, I remembered a story that was ancient before I first started learning much. It’s the kind of story that used to begin:

    “…It was; and it was not…

    “…that there was an old employee in the finish department whose sole job it was to polish lids. As it came to be time for him to retire, he was assigned a ‘young apprentice’ to train. After several weeks, the apprentice asked the old timer how he knew that he was done polishing a particular lid…to which the gent replied…

    “Oh…they come and take it away and bring me a new one…”

    baDUM!

    I knew you would.

    Kind regards.

    Horace

    My go-to method is to moisten a cotton cloth with water, wring it out, wring it out again inside a towel, the proceed to clean the surface of the case.  This is cleaning only.  Enhancing or restoring the sheen of the polished surface is a different project, but the title of this thread specifies cleaning.  I forget where I learned this method, but it may well have been on this forum several years back.

    I asked around the factory yesterday and the way this was achieved was to first coat the piano in lacquer, and rub to a satin finish like a typical New York Steinway, then coat it again with lacquer and polish with a buffing wheel. 

    This was difficult to achieve as the lacquer is very thin even with the extra coating. There was also a risk of melting the lacquer with the buffing wheel if your rpms were too high or you stayed in the same spot for too long.

    The only way to restore it is with a buffing wheel. Use caution!

    Thanks for making the effort to try to get to the bottom of what we have here, Daniel. Your readiness to find out what's what and your good communication skills are a credit to your employer.

    Best,

    Alan, they say that the road to Hell is paved with good intentions.  Unless you have extensive experience in lacquer refinishing or have been trained in touch up repair and do it regularly, you do not know what you don't know even with our (somtimes less than) sagely advice.  As Daniel said, those finishes are thinner, and rub through is always just around the corner.  You may serve your school better by saying that you do not feel that you have sufficient skills to do a proper repair, and you are running the risk of making it worse and not better.  You are obviously a fine technician, so no harm, no foul.

    William,
    I had no intention of attempting to refinish this or any other piano myself, but I appreciate your "don't go there, girlfriend" caution just the same.

    Also appreciated is your leap of faith in surmising that I am a fine technician, having read my posts but not having followed my work. Back at you!

    I have had a private exchange concerning this thread with Doug Wood. He has graciously given me permission to share the upshot of that communication with the "communities" to which I originally posted.

    Doug wrote:

    Hi, Alan, I saw your post on CAUT. That is probably nitrocellulose lacquer rubbed out to high polish. I've see two such pianos, one done at Steinway (in NY) and one done here in the Seattle area by the (at the time) top refinisher. If I was presented with this issue, I'd most certainly contact a top-level touch-up/refinisher for advice. If you have one in your area.

    ...and later, after I sent him the serial munber of the piano in question, just to see if it was one of the two like this that he was familiar with, he continued:

    "When I started working on new Steinways (1987), one could special-order a high-polish finish. For extra $$, of course. I don't know if Steinway NY upgraded any of those pianos in-house, but I do know that some, at least, got sent out to a private concern to get the high-polish finish. Some, at least, were done in lacquer. Some may have been done in polyester-not sure about that. And, of course, Hamburg had high-polish already as their standard finish.

    If this was actually "French polish" alcohol is the solvent and using alcohol will soften or remove the finish!

    Water or water based cleaners might spot or bloom (turn white) a shellac based or French polished finish. If you tried water and isopropyl alcohol and it wasn't a disaster you probably have a lacquer finish.

    If you had dirt or grime to remove lemon oil or other oil-based finish treatment will work.  

    Howards Restore a Finish is safe, though it won't do much for a black finish, but a Sharpie will color in any worn edges or lighter marks.

    Waxes are also safe and might help to remove dirt and grime.

    Actually...if in fact one was wanting to aggressively improve the finish (without refinishing), I think (repeat THINK) French polishing might be the way to go, though if one is a newbie to it there is definitely a learning curve. Since "shellac sticks to everything and everything sticks to shellac", if the underlying lacquer still has its original integrity, a good polisher could simply build on top of what's there with shellac dyed black. 

    I have successfully patched in cheek veneer replacements using FP, as well as various other touch up related areas, even "sprucing up" a complete piano once. It ain't quick, but it's a great skill to learn.

    He may not agree (or want me saying this), but Tim Foster, RPT has learned to do it extremely well, and is a good source if needed. 

    Alan,

    I know you don't want to do anything like that on this piano but I thought I'd throw it out there anyway. 😉  😃

    Thank you for this and all your other contributions to the "hive mind," Peter (and for outing Tim Foster!).

    Hi Alan,

    In the picture below, my French polished Knabe model C on the left and my Yamaha C5 polyester finish piano on the right. This is my first attempt at French polishing and overall, I was very pleased with the result, though my techniques have improved since then and one certainly can find places for improvement. Unfortunately, I haven't had another opportunity to French polish high gloss black since then, though I've French polished mahogany pianos. I intend to do another gloss black, hopefully next year with some improved methods. 

    If the finish on your piano is very smooth, you might be able to French polish over top of it with good results. However, gloss black is much more finicky than natural wood finishes. The finished product would need to be with a very fine cloth on the outside of the rubber, and a very thin shellac, possibly 1 or even 1/2 lb. cut with black wood dye (not stain).
