I sprayed the handles of my Cabas piano years ago with Apple Garde and the one application had prevented darkening. Just sprayed them again recently. I didn't do anything to the Speedy, hence the darkened handles. Not sure how to lighten them so I just leave them be but honestly have not used it in years.Thanks! Handles on the Speedy are a bit worse than yours, I must say! But I got it for a steal, sooo...
Nope, I just got it from YC. It's in great condition for being 13 y.o.

I would love to lighten the handles on the Speedy but I'm afraid to delve into that haha! (Twilly?)
