Review on Defunkify Odor Remover Spray - Crushes Odor with Ionic Silver & Pure Essential Oil Scent - 32 floz (2-Pack of 16 floz bottles) - Fresh Air Fragrance by Robin Crane

I was skeptical that Defunkify would be just another odor masking spray but this stuff really works. When my hiking boots get really wet on a multi-day hike, I take out the insoles, let the boots dry and air them on the porch, then apply a good coat of baking soda to the bottom of the boot and an hour later spritz on Defunkify. After a few hours, slap your shoes together and shake out the baking soda, then do the same with another batch of baking soda and Defunkify.
