ature’s Miracle:Commonly used as a pet stain and odor remover (stick with me on this one), the solution can actually be used to remove stains and odors from clothing. Made up of nothing more than water, enzymes, and alcohol, Nature’s Miracle will break down the fatty deposits and bacteria stuck in your synthetic clothing fibers. Simply soak the offending areas before throwing in your regular wash. My polyester outdoor gear came out miraculously stink-free.
Baking soda: Much like you would for a bee sting, make a paste of baking soda and water to rub on the offending areas. Let sit for awhile before throwing it in your normal wash. You can also add a 1/2 cup of baking soda to the rinse cycle to remove general odors. The paste solution seems to work for mild stink as routine maintenance, but not on baked in odors.
Vinegar: You can add a small amount (1/2 cup-1 cup) of vinegar to your wash load to help break down oils and kill bacteria. Use sparingly, as your clothes can come out smelling like vinegar which makes wearing them again a bit of a nightmare.
Salt: I was a little skeptical about this one at first but the science makes sense. Salt is a natural anti-bacterial so will kill those critters lurking in your synthetic apparel. Simply soak the offending item in a salted (few tablespoons) bath of water before throwing in the regular wash.
Nature’s Miracle is by far and away the home remedy winner for me. As soon as I get back from a ride, run, or other outdoor activity, I spray some on the offending areas of my synthetic apparel then throw them in the laundry basket. After washing, the stink is gone.
