    List

    As you are aware, Pianotek's go-to bushing and mortice restorer, VS Profelt is no longer available in the USA.  However, I just came across a very good substitute to that solution found at Howard Industries. Just did a treatment on a Steinway D and the results were excellent. Its being labeled as "VS Profelt Alternative" for $25.95/bottle.

    How very interesting. What does it actually do? Release squashed fibres? The equivalent doesn't seem to be known across the pond from the British supply house https://www.fletcher-newman.co.uk/index.php

    Best wishes

    I am vague on the details but about a year ago, Chris Brown of GrandWorks Regulation Products, had a snippit in the Journal that the Dampp Chaser Water Additive had restorative properties very similar to ProFelt. Worth searching the Journal Archives for this. I did watch the video.

    Tremaine,

    An AI BOT came up with this little piece of information regarding CAS 68424-85-1 which is evidently the active ingredient in DC pad treatment:

    "CAS number 68424-85-1 corresponds to a chemical compound known as Quaternary ammonium compounds, benzyl-C12-16-alkyldimethyl, chlorides. This is a type of quaternary ammonium compound, which is a class of organic compounds with a wide range of applications, including as disinfectants, surfactants, and fabric softeners."
    This would explain WHY it has an effect similar to Profelt.

    Not sure of the chemical properties, but this type of material has been longed used at Kluge and other European felt manufactures as a stabilizing agent used in felt manufacturing.  Pianotek started selling this as "VS Profelt" some years back and it has been a staple with many techs.  Its great for resizing key bushings, as was a balancier holes that have become sloppy, as well as key mortices.

    For stabilizing key bushing mortices, simply put a few drops on each side, and then put the appropriate caul in place.  Leave set over night, and the mortice will size appropriately to the caul dimensions.

    For stabilizing key bushing felt after installation, same process, add a few drops to each side, then put the appropriate caul in place and let set over night.

    There is an outfit in Germany that currently sells the same product, but at the moment, the name escapes me.

    Schaff has announced that it too has come up with a solution similar to the VS Profelt and will be available in the near future.

    I've long used VS profelt as my go to solution to reduce friction in flanges that are in good condition but just tight and repinning is not an option.  (Not for verdigris or otherwise polluted felt and metal.)  Soak and work them a bit, then let dry over night and the results most often are striking and lasting.    I heard from a little bird that it has a small amount of silicone and contains water.  These two components would contribute to reducing flange friction.

    Hi Tom,
    I believe this is the German supplier you're referring to (Jahn Pianoteile, the product is TRO-FEX by Kluge):

    The wool fibers are hollow and normally have lanolin in them. After processing the lanolin washes out. Pro felt fills the fibers. They used to use it to retain the shape of wool hats.
    For sizing bushings it swells up the felt just like alcohol and water and the felt gets crushed together. When it dries it is able to shrink more than it was. Pro felt is better for the felt than alcohol.

    I have been an avid Pro Felt user for years and bemoaned it's loss. Recently purchased a bottle directly from Felt Restore-

    https://feltrestore.com/

    which smelled exactly like isopropyl. Have yet to use it on a full set of keys but it seemed effective on samples. I would prefer to find something more like the original and am waiting patiently for it to appear.

    Matthew,

    With all due respect I want to alert you to the fact that recently there has been serious controversy on these pages over using the "list" to promote/sell products or services. Technically speaking your post should been flagged and removed so as to be consistent with the guidelines concerning this issue.

    However, there is a serious double standard that exists here. I am NOT taking any sides here but remain neutral on the matter. The moderators though, and online participants, seem to have chosen to do so. I am simply taking this opportunity to warn you that your post MAY get flagged and removed (I'm not going to flag it), as per the "rules" for using the forum if the arguments that have recently been presented are in fact going to be enforced clearly, fairly  and consistently. 

    In no way an I attempting to provoke a fight. However, as the saying goes: "Whats good for the goose is good for the gander", since they're both geese (if you know what I mean). OTOH if you're new to the forum you may actually know little or nothing concerning what I'm talking about. There are plenty here though who DO know. I'll leave it at that. (It's good to know though that there are now several profelt alternatives available, yours being one of them).

    Thank you Peter!  I was unaware of the guidelines which makes great sense. I didn't see a way to edit or delete my previous comment.  If there is a way to do so then I will take care of it.
