If it is a good, sharp, high-quality lens that you were satisfied with weh it was clean, do not attempt DYI cleaning, do not place it in an oven or put it in a jar with foodstuffs. Send it into a proper repair service and have it

Desiccants such a silica gel will prevent a build-up of moisture but it won't' remove the damage case by existing moisture.
