I don't know if anyone else has this problem but my hands are just naturally generally sweaty (more so if it's hot) and for some pieces it's especially hard to play because my hands tend to slip off the sharp keys at times. At the moment I just use napkins and wipe my hands and keys as often as I can but does anyone know any preventive measures or have any tips? I know there is no proper cure but has anyone tried a product that seemed to work? I tried Certain Dri even though it's supposed to be for the armpit I saw reviews that it worked for some people's hands. It didn't for me though.

Thanks.

I have the same problem, and much worse if I'm nervous. I wish there was a way to keep my hands from sweating
Maybe someone will post an easy solution.
