One of our academy etiquette rules at Creighton MMA & Fitness is to always come to class with your uniform, (Gi, t-shirt, dri-fit or rash guard), always clean and odorless. If you train on a regular basis then eventually your long days of sweating and training will catch up with your uniform/clothing IF you do not wash it properly each time. I have found that the bast way to keep your training uniforms clean & ODOR-FREE is to combine these (3) detergent/disinfectants together. I like the 1. Gain laundry detergent that has the febreeze in it combined with 2. Odoban (you can purchase this at home depot in the cleaning section) and 3. Clorox 2 for colors. The Odoban is an odor eliminator and kills 99.99% of germs: This is a list below of what OdoBan does:
What is OdoBan®?
A Deodorizer… eliminates unpleasant odors on washable surfaces such as upholstery, carpets, bedding, showers, walls and floors while leaving a fresh scent.
A Sanitizer… kills 99.99% of germs such as †Streptococcus pyogenes (Strep), Escherichia coli 0157:H7 (E.coli)(pathogenic strain), Listeria monocytogenes, Staphylococcus aureus (Staph) and Klebsiella pneumoniae on hard, nonporous, nonfood contact surfaces in 60 seconds.
A Disinfectant… fungicidal against germs ‡such as Trichophyton mentagrophyte (the athlete's foot fungus), when used on surfaces in areas such as locker rooms, dressing rooms, shower and bath areas and exercise facilities.
A Mildewstat… effectively controls and inhibits the growth of mold and mildew.
A Virucide*… kills *HIV-1 (AIDS Virus), Influenza A/Hong Kong and Herpes Simplex type 2 in 60 seconds.
I also put Clorox 2 for colors in as well to help make sure and reinforce that all the sweat and smell is out of my shirts and Gi. Also remember that after your training session don't let your clothing sit overnight or days before you decide to wash it. When you get home throw your training clothes in the laundry and begin the cleaning process immediately. Let's continue to keep our equipment and clothing odor free and clean when we come to the academy. I promise, your training partner will thank you.
