I poured an OxiClean solution into the body and head. Let it fizz for awhile, then rinsed out and cleaned remaining mold out with a toothbrush and pipe cleaners. If you rinse with hot tap the body gets more pliable and easier to get into the feet. Then I followed up with soaking the inside of the body with a bleach solution to make myself feel better about the mold being completely dead. For both the oxyclean and bleach solution, I put the head in a cup of water, so if any solution leaked out through hair plugs it would be diluted and not alter the outside of the body. This is my first experience. Never done any of these things before. I'm a total newbie. Everything came out super clean.
