Bill/others: I just looked up my earlier response to the use of alcohol, and feel that, for a change, I may have used too few words. <G> Like others, I have successfully used alcohol for cleaning. I feel the keyword in my reply was "indiscriminate". The implication was that of customer usage, but it can apply to techs as well. More than once, I've just entered the scene and been handed a collection of ivories and asked to reinstall them. Ivories that were not loose were clearly raised at the edges, indicating (to me) that the wafer to ivory bond had been undermined via soaking action, and/or the ivories had warped, causing the bond to fail. It is here that the customer volunteers that alcohol had been used for cleaning. It may have been something *other* than alcohol. I can only repeat what was told to me. This is a rough parallel to customers who spray 'Pledge' in the tuning pin area, then, when loose tuning pins result, assure you they've done nothing but dusted the piano. Ballard mentions scrubbing pad and paper towels which are indicators of *proper* usage, i.e., maintaining an element of control. I have the impression that these customers did not have the benefit of any fast-drying characteristics of alcohol. They may have just poured it on and let the wetting action begin. Or, they may have run the keys through the dishwasher. I'm only aware of the results and the customer's story. However, (a) I find it difficult to believe that I'm the only person to have experienced this, and (b) I wonder whether your, or my, or the customer's alcohol is rapidly evaporating, or being absorbed through the pores of the ivory. Regarding using milk: I too prefer my milk with cookies instead of piano keys. Although I've never tried it, I don't think there's anything particularly mysterious about it. Anyone who's noticed the film that has dried in (what was) a glass of milk will note the 'whiting' characteristics. When dried, this can be quite difficult to wash away. Also, there's no denying that milk is wet, therefore it qualifies as a "solvent" in the same category as water. I suppose 'KoolAid' or other foods or beverages could be substituted to provide additional color selection, providing sugar is not added. My preference is to clean keys, not whitewash them. This thread started with a message ported over from another list, wherein vodka was being promoted for cleaning ivories. Perhaps there's another, more obscure message in these threads. It involves what *we* do to pianos versus what *customers* do to pianos. The current subject is cleaning ivories. It could just as easily be (piano) cleaning, adjusting pedals, or tightening a bench, to name a few seemingly innocent examples. Maybe I'm getting old and grumpy, but I prefer that customers just stick to playing the piano. I'll take care of the rest. Jim Harvey RPT ______________________________ Reply Separator _________________________________ Boy that's news to me! Alcohol is my solvent/cleaner of choice because as I explain to my customers, the alcohol evaporates before it has a chance to warp the ivory (unlike water). It evaporates so fast that I have to have the alcohol/felt scrubbing pad in one hand and paper towel in the other so that I can pick up the grime before it dries out on me. Tell me, how soon should I be seeing undone glue bonds? I've never heard of this......Guess I'll have to start hitting up my customers for a glass of milk (-I'll take a cookie with that, please).
