Fixing a vibrator’s outside coating

I’m not 100% on where to ask this but I’ve had a waterproof vibrator that’s got the really soft and smooth texture. It has with a warning that it coming into contact with pvc plastic will melt the plastic of the vibrator. Long story short my boyfriend left it on a plastic shelf that is made with pvc (ugh) and didn’t know it would effect it, and later I discovered two small lines in the outside of the vibrator. They kind of look like cracks but I’m not sure. Is there a way to fix it? I’m afraid to use it now and really don’t want to shell out money to buy a new one.
