Fragrance free, chemical free, biodegradable and non toxic. No pumps, sprays, powders, perfumes or residue! Reuse for up to two years. To rejuvenate just place the bags outside in the sun once a month for about an hour. Give it a day or two to really start working.
At first I wasn't sure but after about 24-48 hours it worked great. Works great in hockey bags, you can drop one in the dirty clothes basket.
love these odor absorbers, and the fact that they are reusable and sustainable. An all around great product! No chemicals, and a persistent, stubborn mildew odor is totally gone after just a few days of use. I would highly recommend them!
