take the lens out, wash them in the washing machine and then dry them with a hair dryer, you have to get them dry fast so the bacteria wont form again and make the smell come back. i have had this exact same problem with my I/Os, they got wet, i didnt dry them, they got smelly. i did the afromentioned steps and it worked and until i got them wet and smelly again and then they got stolen, jokes on you fucker.
