When gigging or doing demos, I always take a small bottle of Purell Hand Sanitizer which has Aloe in it. I use it after I wash my hands, before, and sometimes during a performance. I also use it after shaking hands with people and just before I get back to playing.

I find it feels great and keeps my hands smooth, and, they slide perfectly on the keys, as well as keeping germs and bacteria away. It does not dry out my skin.

I always take a bottle of it to the grocery store and use it after packing groceries in the car, and after putting them away in the house.

I'm not a "clean freak" by any means, but the Purell makes playing much nicer, and with the added benefit of helping me stay cold and flu free.

PS...I also wipe down the keys on my Tyros4 once a week.
