Hello list, I did once do the bass strings on a relative's piano as an experiment (1963 Yamaha C3)...dead tone but quite ok bearing. I didn't have much ideas and I was ignorant to the effects of many string-abusing solvents at the time, so i scrubbed the string with steel wool to remove the dust and surface grime then soaked it in petrol for 2 hours, then a dilute hydrochloric acid solution for about 1/2 hour (i tried just ONE string at first) the results were amazing really.....it got back it's roar and might...but i wouldn't try it again...the thinner bichords nearly dissolved in the acid! So far it's been 3 years and the strings are still doing ok....no rusting/strength problems....and the piano's tuned to 443 by the way :) Amery Singapore (60-100% humidity) __________________________________ Do you Yahoo!?
