<HTML>Hi  All My Name is Wally and I joined the list a month or so ago. I don't have m= uch to say so I just look. Well, to the point of the under water Yamaha's I = have serviced 2 different Model P22 pianos one was where a new roof was inst= alled and the first storm that came through on a weekend at one of my school= s and the water came in on it for 2-3 days,  A month after they told me= that it was taken in to storage at a local warehousing Co. and It was full = of nasty black stuff.  At this point It looked as if it may be a total = loss. I had the movers bring it to my shop and took it apart, took the keys = out and went to work.  I washed the keys with bleach (yes the stuff you= do laundry with) and washed them in the sink. ( crazy right, but you can't = hurt a total loss) Well the black for the most part washed off. With only sl= ight staining, same for the key bed. I let the keys dry over the next week, = refelted the key bed and put the keys back in. all the keys had swollen and = some had warped, 4-5 real bad so they needed some major adjustment so back t= o the sink to be soaked again, this time I put a large C. Clamp with the scr= ew to the side I wanted to warp. (Yes, and this worked) Well so much for thi= s, the rest of the action did not seem to have gotten much water on them. (4= -5 hammers showed damage but dried well) I kept it in the shop for 6 months = after to see if there would be more damage but none. This piano is still in = use today it should be about 10 Yrs. old now. Thanks Walter Oventrop RPT St. Louis, MO</HTML>
