I have a Yamaha 21 practice alto that I haven’t used in over a year due to various circumstances. I got it out last night, and going through my pre-practice routine I noticed minor verdigris on some of the closed key tone hole rims and pads. The horn was checked by a reputable shop before it was stored, given a clean bill of health, and hadn’t been played since. It lives in modern case, not its original shag carpeted one.
I’m finding lots of great help on removing the green gunk from the metal, and suggestions for additional preventative treatment if needed (never had this pre-storage). I’ve cleaned up the tone holes with lemon, and I know I’ll have to do it again since the pads still have green on them.
1. Why is the problem only on some of the upper tone holes? The larger closed ones are fine.
2. My quest now is to get the verdigris off the pads and out of the impressions. Cleaning paper didn’t do much. The pads are recent so I don’t want to replace them out of hand, or damage them trying to clean them.
