Using an unclean toy is almost like unprotected sex. Without proper cleaning, a toy may become a breeding ground for things you don't want in your body.

After toy play, spray the toy with a complete coating of the cleaner. Wipe the toy with a clean cloth and rinse the toy with water. Air dry the toy for the next use.
