You should get into the habit of always carefully cleaning your own sex toy with soap and warm water every time you use it. Using a condom is a very convenient way to avoid having to wash the toy each time after each use.
Sex toys which have a motor should not be soaked in water. Sex toys that vibrate should be wiped with warm, soapy water and left to air dry. Even waterproof vibrators, which work fine in the bath, should not be exposed to the boiling water of the dishwasher.
Silicone sex toys are usually the best choice because unlike jelly rubber, plastic and latex toys, they can be sanitized by submerging them in boiling water for four minutes. Other types of toys cannot be fully disinfected.
For toys made from jelly rubber, plastic and latex, clean them with warm water and a mild soap. Jelly toys will degrade if washed with strong anti-bacterial soaps and can even melt if boiled.
When sharing a sex toy, it’s always good practice to use a condom with it. If you only use the toy for yourself, take the time to wash it after each session, and then disinfect the toy every so often.
