Water works fine, on coffee and booze. This is one time to give the solvents a miss. Regards Roger>> This is the first time I ever heard that a wound string has a finish! Remember, I suggested acetone for cleaning a sticky spill from a wound string or from other places where there is very bad contamination such as in flanges. This could apply to the agraffes but only if the contamination is really tough to break up and yes, you wouldn't slop acetone all over everything, it would take most plate finishes right off. Over 15 years ago now, I freed up a hopelessly stuck action from a Bechstein 9 foot grand at the Frank Lloyd write estate. That was before there was Protek. A few different technicians had tried a few different sprays, WD-40, Silicone and I don't know what else. I started with pure acetone to try to loosen the contamination. I put on repeated applications, worked the parts vigorously and let the action dry in the hot sun and stiff breeze there was that day. I followed up by mixing in 70% Isopropyl Alcohol, again with repeated applications and vigorously working the parts. I ended by adding distilled water to the mix. Each drying period went rather quickly because of the temperature and wind. Believe me, I know better than to breathe that kind of stuff. I wore a respirator even though I was working outside in a strong breeze. The end result is that to this day, that action is free and works fine. I was the only one who was able to fix it and therefore I got the job of taking care of the pianos in that vast estate: 2 Bechsteins, 3 Steinways and a Yamaha. They are all tuned in EBVT and all used for either performance or rehearsals before performances. And yes, Joe, I routinely use a hair dryer to quick dry a bit of acetone that I might use either for defeating contamination or for hardening hammers. I've never started a fire that way. I should note however that this is not a daily routine and that when I do something like this, relatively small amounts of solvent are used.
