Cleaning
After using your toys, you should always wash them, thoroughly, with an antibacterial cleaning spray or with lukewarm water and neutral soap.
Leave them to dry naturally and store them in their original box or in a plastic storage bag, away from heat and light.

Metal toys may be sterilized in boiling water or even washed in the dish washer.
You may use any lube with metal toys.
