Always clean your toy thoroughly before and after each use with clean warm water and soap. Rinse and pat dry with a lint-free towel or cloth.
For those times when you need something quick and discreet (like when your roommate is using the bathroom for karaoke practice), you can also use a gentle wet wipe.
Always store toy with its lid on, to avoid dust build-up or damage from other materials, and to keep it safe from sunlight or other extreme heats.
