Maybe some of you like the sweet taste you get in your mouth after breathing in the dust, but I think you better be carefull with the oxidised lead. Use a good vacuum cleaner when doing the job. Any thoughts how it became oxidised in the first place? To my knowledge good pure lead lasts thousands of years (the Romans used lead piping in their bathhouse in Bath (GB) wich are still intact), so why does it oxidise in some piano's? You can even have very good leads and very oxidised in one piano, even in one key. Impure lead? Something in the wood of the keys? _______________________________________________ pianotech list info: http://www.ptg.org/mailman/listinfo/pianot _________________________________________________________________ Get reliable access on MSN 9 Dial-up. 3 months for the price of 1!
