First get rid of mildew with bleach or odo-ban cleaner. Then, I’ve got a great odor eliminator solution that I’ve used myself and safe and totally fragrance free. . Go out and get a couple of the FRIDGE-IT activated carbon odor absorbers – little purple cube – not the imitations. costs around $3 dollars each and place under sink. Totally unscented so it actually eliminates odor rather than covering up with some nasty fragrance.
I’ve used these for worst smells including spoiled fish in car and for closets, fridge etc. they are FANTASTIC> No spills or chemicals to worry about. You can buy these in kitchen gadget stores or just go direct which is what I do – contact them at firstname.lastname@example.org and ask for order form. You get it right away. I also noticed they now have a product just for litter boxes.
Definitely the way to go. try it.
