There is a product called "No Rinse", a moisturizing body wash that you just wipe on to clean your skin anywhere on your body. There are probably other brands available for the same purpose. It says on the bottle I have "Used by NASA". If anyone would have a problem keeping fresh, it would be an astronaut.

A medical supply store would probably have such a product in stock. I got mine on the internet.

I hope this helps. Regards, Lil
