There's no reason it would damage the silicone, since it's the same as any silicone dildo that can be bleached. The only way it could ruin your vibrator is if it got into the charging port or buttons. I have bleached my Forms and Jopens, amongst others, with no damage. For the Forms I make sure just to dip the silicone portion into the bleachy water, not the metal part that's the charging contact. The same goes for Lelos or other toys with plastic bases, I only put the silicone parts in the bleach. For the Jopens you should be fine putting the whole thing in since it's entirely silicone and waterproof. I've still always kept the charging port out of the bleach, although that's not really logical since I've submerged them in water. Guess I just like to err on the side of caution.
