Does anyone know what the ratio is of alcohol to water? I have a sluggish damper system to deal with this week. I've tried Goose & Protek but it doesn't last, so I'm going to try alchol/water. I suppose hair dryer would be helpful but I imagine it will wreck havoc with the tuning...maybe just the air moving no heat? If I'm making it up myself, what is the ratio of alcohol to water? 1 part water to 5 parts alcohol.

Is the piano in a moist basement? ..or has it been recently moved from a moist place into a home? If recently moved from a moist place(baseement or garage) into a home, then in a coulple weeks the moistrue will dry out of the bushings a it sits in the heated house and everything will return to normal by drying allittle. If not, then the bushings of either the jack or the hammer are swollen and need a shot of 5% to 10% alchohol to H2O(water). There are disputes on the percentage of water to alchohol and the TYPE of alchohol. I do about 10% alc to H20 and the alchohol is isopropyl, because I cant get Ethyl anymore. Works for my customers, fine. Julia Reading, PA Julia, Not my experiece-- When they get sluggish (as in the classic Acrosonic sluggish ) thay will stay sluggish in the Sahara . I see Acros in January here in the northeast @ 20% RH .as sluggish as can be. I do agree -- Alc., Water to shrink ,and or protek will usually work. I just don't see swollen action center bushings "retreating" to normal without help.perhaps your experience is different. As an aside, you can jump through all kinds of hoops trying to get certain types of alc. but the cheapest vodka at the packy works great--Just don't bring it in the ladies house still in the bottle-- the neighbors might talk! Percentages ? Heck the stuff is alcohol and water and is clear . I think we sometimes get too carried away with exactitude with this kind of thing. The alc. brings the water to the cloth and the bushing will shrink. JMHO, Tom Driscoll RPT ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
