I'd highly recommend against acetone or nail polish remover (which used to be acetone, but now may contain who-knows-what). Acetone will damage many electronic components, including switches.

Isopropyl alcohol is highly recommended, though try not to get it into the switches.

In the US, avoid "rubbing alcohol" unless it is specifically "isopropyl rubbing alcohol". If it doesn't say isopropyl, by law it is ethyl alcohol with deliberately introduced contaminants including acetone.
