Hi Jill, Some years back there was a tuning pin tightener fluid that was black, darker than even truck stop coffee. Obviously not applied thoughtfully or carefully. Truly uglifying stuff. First, if there is corrosion on the strings, as opposed to stains, they should be replaced, especially in the treble where the tension can be 60% of breaking strain, or more. They _will_ break. If only stained it should clean off the strings with wet cloth. No hope of getting the stuff out of the felts. I would suggest you write up three estimates, one of absolute requirements, one providing a well functioning and durable instrument and one providing an "as new" instrument replacing all parishables. Let the customer decide where their priorities lie. Don't make a recommendation that doesn't bring the piano up to a standard that you are not willing to service for many years to come. Keep in mind that there is a level of expectation (and cost) of a technician and a different set for the customer. Other factors that influence your decisions are: soundboard condition in terms of crown, bearing, glue joints, cracks and stains Bridges; bearing cracks loose pins String; age, condition, rendering, tone (bass), number replaced, underfelts. Lyre, pedal and trapwork condition Dampers, guide bushings and damper action condition Hammers and shank conditions Wippens and felt conditions, Keys; bushings, covers, key end felts, backchecks, balance holes and capstans Keyframe, warpage, felts, pins, Anything else you can think of. I hope this really muddies the waters. Newton Hunt New Jersey (formerly of Deming, NM)
