Never share sex toys unless everyone using it puts a condom on it. Sex toys can safely be washed in warm, soapy water. This should be done regularly, condoms or not.
If you use lubrication, use only water-based - oil-based lubes can eat right through a silicone vibrator.
If you are using a non-conventional vibrator (like something you found around the house) make sure it's got no sharp edges and it is clean, clean, clean. [ alisonmarie's advice column | Ask alisonmarie A Question ]
