What kind of cleaning chemicals?
I just use 3M cloth to polish. The wood these days seem different. Last time, my old old piano (when I was kid), I really use Lemon Pledge and it worked great. My piano now just use cloth and rub nice nice to a shine.
I leave my piano lid open, so always need to have 3M cloth to standby and wipe all the dust and \"oil\" off the keys. But then having an open piano means my little 4yo would play on it every so often when he walks past the piano. Can be exploring tunes of his own or tunes he's heard before, or even working out his own songs that he's doing for lessons.
Yamaha sells one, its about $40 plus for a small bottle. Otherwise, if you do not want to spend too much, you can buy Pledge from any supermarket, it does a great job too!
I just cannot stand the dust all over the piano, it does not help even with a full size piano cover, so always have those microfiber cloth beside the piano on standby mode
