We tried freezing, febreze, lysol, odor eater powder. . . Nothing worked. Decided dd must sweat toxic fumes.
DH finally grabbed some of those sneaker balls at Walmart. We sprayed everything with apple cider vinegar, let it dry, then threw those balls in her bag, in her cleats, and inside her glove. Let them all air out.
Didn't take the odors entirely away, but at least we don't have to duct tape the glove to the roof of the car now - and it really did wonders for her bat bag and cleats. Ziploc bags for travel are a must. Dd is such a sweet kid, with such a smelly problem! �� Good luck!
Drying in the sun will help too.
