For years I was battling with the horrible odour coming from my kid's Sailing booties and wet gear as well Hokey Gear and running shoes.
I tried using Fabreze, and other clothing and air fresheners, but it only masked the smell.
A few months ago, my friend who had the same problem with her kids and husband's gear introduced me to a very effective product called Stink -Off wet gear.
Apparently, it is an environmental friendly product, It works incredibly well, safe to use all the equipment and smells great. The only thing is that you can only purchase it on-line.
www.stink-off.com I highly recommend it!
