Hello everyone, first of all, congratulations on this beautiful and very precious forum.
I have an upright piano, recently acquired at a flea market, a truly beautiful vertical piano (brand UHLMANN, Fovarosi mechanics, etc., etc.), which struck me for its lovely timbre.
While cleaning it, I discovered that quite a few keys (about 30) have been attacked by woodworms, and I was about to syringe them with a liquid anti-woodworm product... but only now am I doubting whether it is a good idea to inject this substance into the wood. I am asking you experts if instead it would be better to "gasify" them by taking them to some center.
The gas chamber is more invasive, sometimes it also ruins any wood treatments and some glues.
I recommend Xilamon injections, keeping in mind that woodworms make galleries upwards to avoid the sawdust, often in an L-shape.
Don't wait until July and August because woodworms lay their eggs during that period (on average 50 per worm) which are immune to anti-woodworm products, so you must kill the worms before they lay eggs.
After injecting the Xilamon, possibly with the key inverted, the gallery can be closed with adhesive tape or with wax (the same color as the wood). Keep in mind that the woodworm prefers to live in slightly damp and quiet environments.
Yes, in fact, by playing, the woodworm should disappear. The fact is that where we see a "little hole"… the woodworm has already come out. Unfortunately, there are others well-hidden in concealed areas… so… play!!!!!! Good Music
