Applications and Tips

OdorKlenz Sport Laundry Additive is the perfect complement to your detergent. Detergents do a great job of making your athletic gear look great, but they often have difficulty making them smell great. Just add the OdorKlenz Sport Laundry Additive into your wash and the job will get done. Since body odors are a complex chemistry of acids, aldehydes, sulfur compounds, ketones, and amines just to name a few, you need a product and technology that can attack and break them down. OdorKlenz Sport Laundry Additive uses earth minerals that have been enhanced with greater surface area resulting in more chemical activity towards odor-causing chemicals.

– Use wash cycles with more agitation
– Use warm water instead of cold
– Use an extra rinse at the end of the cycle
– If your machine dispenses laundry products at timed moments in the wash, make sure to deploy the OdorKlenz Sport Laundry Additive during the main wash and agitation cycle, not in the prewash or final rinse cycle.

Do Not:
Use any prewash or presoaks cycles. Please do not use prewash or presoak cycles. If your machine has these types of cycles and you added the Sport Additive to the washbasin, it will likely be removed from the wash before it has any time to interact with the odor source.
Allow the laundry additive to become folded inside of fabrics. Please do not have the additive in a situation where it does not freely move within the wash. Since our product does not behave like laundry detergent, it needs to be able to freely move within the wash to come into contact with the offending source odor.
Overloaded wash cycles. Overloading the washing machine makes it difficult for the product to work effectively. The level of contamination may be too much for the recommended dosage and the product may not be able to fully make contact with the source of the odor in the wash.
Use in combination with bleach, vinegar, or other additives.


Great for all washable fabrics including:
– Yoga Pants
– Sporting Fabric
– Sport Uniforms
– Active Wear

  1. Jordan B.

    Removed all outdoor activity sweat soaked clothing when all others failed.

  2. Miranda L.

    This is great! I was worried it would not work and/or would cause skin irritation but it did not. This product has saved so many of my work clothes. I’ve had issues my entire life with under arm odor and because I use natural deodorant it happens often. This product has completely removed odors.

  3. Cassandra D.

    I am very pleased with this product.

  4. Ryan L.

    I can’t believe it – it actually works! I bought this on a lark. I work out once or twice daily, so I always have a big pile of dirty running clothes that needs washing. The odor is unpleasant, and I came across this product and thought I would give it a try. It works really well and eliminates both sweat-related odor as well as mildew-related odor as well as mildew-related odor, without leaving behind a scent of its own. The bad odors is just “gone”, with no replacement. Very cool.

    On the downside, this product does tend to leave behind a little bit of a grainy or powdery residue not unlike what you might remember from the powered laundry detergents of the pre-high-efficiency era. This is not that big an issue for me; I’d much rather brush away some powder after drying my clothes than deal with perpetual unpleasant odor.

    I can recommend this product.

  5. Steve S.

    My pants and were soaked with a quart of gasoline and after 5 washes they still smelled of gas. While airing them outside for 10 days I ordered OdorKlenz and washed them. I cannot smell anymore gas smell.

  6. Earle E.

    My college athlete washes his workout clothes about once a month. His dorm room reeked! Several normal washes would not remove the smell. Until now, I has to soak overnight in a diluted vinegar bath, but they smell like vinegar, and he would not do that in college. OdorKlenz works well, but I have to double up per load. The clothes smell slightly like the raw product, but you have to look for it. I haven’t had the chance to try it on month old clothes, but I am encouraged that this will work for him in college.

  7. Lacey G.

    We left some towels out on our deck where we had been sitting outside and some cats or something left some bad odor on them. I didn’t think the smell would come out so I tried the OdorKlenz and it worked great. Also works on my dogs “bath towels” and her bedding covers. So glad I found this product.

  8. Quin B.

    I backpack quite a bit and have synthetic fabrics that just won’t clean well as far as smell goes, but this stuff fully removed the odors from my clothes!!

  9. Aliah M.

    I tried OdorKlenz after watching Emma Abrahamson’s youtube channel. It was inexpensive and easy to order so I gave it a shot. I am happy to report that it worked! My old running clothes smell fresh and new; no more lingering sweaty smells! I also used it on the rest of my clothes and have had great results and most importantly no fabric damage. Thank you!

  10. Jamie C.

    My 2 sons play ice hockey and their stuff can smell!! Lol this works great ?? recommend for sports clothes anything that soap doesn’t take the smell out of!

  11. Cay Y.

    I saw this product in a cleaning blogger on YouTube “Clean My Space”, brilliant idea and this product is what it said it does. I use it on towels and also on workout clothes it works like a charm. Highly recommend!

  12. Janette E

    Works fantastic, I dug out some great old clothes that do not fit. I used OdorKlenz to Wash them all before donating to charity. Works great, removed that musty odor that vinegar, bleach oxiclean could not. So happy, I’m telling anyone that will listen to me!!

  13. Liz P

    Your company consistently provides good service and a great product. The sports additive is an essential product in our home!

  14. Amelia C.

    It seems to handle the job.. a bit pricey, but very good product!

  15. Rosie S.

    I used this for workout clothes and it WORKS!

  16. Melissa L.

    I recently purchased your laundry additive for sports clothes and I am very pleased ! It has saved me from discarding expensive sports clothing. Excellent product.

  17. Pamila M.

    I absolutely love these products! The laundry additive does wonders on my husbands work clothes and makes our towels fresh as new.

  18. Valerie B.

    your product is beyond awesome. My boyfriend is a diehard bodybuilder and his gym clothes get pretty smelly. Sometimes I would wash them twice and it still didn’t help with the odor. But your product is a life saver. Also I used is on my dogs blanket which smelled even after it was washed but OdorKlenz removes the dog smell. I will be using this product from here on out.

  19. Donna R

    I purchased this product and it worked great! I am so glad I found this.

  20. Lori S.

    I’ve been using this and it really works for me! Great product.

  21. David C.

    This product worked wonderfully for me! It completely got the smells out of my clothes.

  22. Michael H.

    My husband purchased this product to use for sports clothing. It worked great and removed all of the odors from our clothes.

  23. William Thoreson

    Great product–gets rid of sweat smell and doesn’t leave a lingering replacement smell!

  24. Taylor Roberson

    Had some DRI-IT shirts that I LOVED, but had started to build up some really funky smell, even after washing them. I eventually had to stop wearing them. I figured I’d use them as yard work shirts or something where it didn’t matter. Then I saw OdorKlenz and thought it was worth the money of not having to junk my clothes. I was impressed with how fast it got here and happier that my clothes have been salvaged.

  25. Virgil Apodaca

    Great stuff – really works! I wish that I could buy it at Walmart and save on shipping 🙁

  26. Virginia Jones

    Works great! If you have an old machine like me just soak clothes for the first load to remove stubborn body odors

  27. Anthony Reid

    Used one bottle over the course of a couple of months. It did seem to eliminate odors.

  28. Dee Williams

    Repeat buyer, great product. I have been using No Sweat odors for almost two years. Works great.

  29. Robert Migliore

    This laundry detergent does exactly as it says and that is killing sweat odors for good. Will definitely order again!

  33. Brain Roberts

    Effective product and solid customer service.

  34. Mary B.

    I’ve been using the laundry additive and I love it!

  35. Jeffery Wooding

    I bought this specifically for my gym clothes and it works well at removing sweat smell and not doing it with some cheesy perfumes. Love this stuff!!

  36. Robert Enriquez

    Absolutely love OdorKlenz It gets my sweaty workout clothes cleaner and fresher than any other product I’ve tried. Delivery was super quick, as well.

  37. Marie Boudreaux

    This is a great laundry detergent for me since it doesn’t irritate my sensitive skin & everything smells so fresh

  38. Sonya Johnson

    Doesn’t have an overwhelming smell I feel like my clothes are actually clean when I wash them

  39. Heather Brown

    I’ve tried 3 other all natural laundry detergents and finally, I’ve found one that’s scent free and gets the sweat funk out every time.

  40. John Reyes

    I used this and thought that it made a slight difference to the sweat odors but didn’t completely remove them

Frequently Asked Questions

Is this safe to use on my workout clothes to remove sweat odors?

Yes. Our product is very effective against body odors. It should be noted that some newer synthetic articles of clothing do pose more challenges for odor elimination.

Is this product safe to use on all my clothing?

Please follow fabric care instructions on the label. If the garment is water sensitive, you should use caution when using the OdorKlenz Laundry Additive. Our product needs water to help create the contact between our active materials and the offending odor source.

Is this product fragrance-free?

We have not added any perfumes or fragrances to our product. We believe that if the goal is to eliminate odors, you should not be adding odors or covering them up.

Can I use the OdorKlenz Laundry Additive to soak clothing followed by a hand wash?

Yes you can. We would recommend our liquid version of the product for this type of application as it disperses better in situations with lower agitation and takes longer to settle. The easiest way to do a soaking step is in a sink or washtub with warm water. You would want to make sure the size is big enough for the clothing. Start with the warm water, add the OdorKlenz Laundry Additive and mix to disperse. Then add the clothing and let it sit for 20-30 minutes and give it the occasional mix to suspend the product in the water. You can let it sit longer if you would like. Then after the soaking, the clothing can be rung out and then taken straight to the washer to do a normal wash cycle with detergent.

What is the difference between the powder and the liquid?

The actives are the same, the difference is just the dispersal material. In the liquid version, it is water, in the powder version it is soda ash. For soaking applications, we recommend our liquid version of the product.

Do I use the OdorKlenz Laundry Additive with my normal detergent?

Yes. We suggest a fragrance-free standard detergent.

Can the OdorKlenz Laundry Additive be used to remove fragrances and perfumes?

Yes. Depending on the severity/saturation of the perfume, a soaking step may be needed.

How effective will this be at removing chemical odors from new clothing?

It depends on if the clothing was intentionally treated with the chemical or not. Some fabrics have chemicals bonded to the fibers, often for wrinkle prevention or some other protection. These can be difficult to remove as they have effectively been engineered to be part of the garment. Other new clothing smells are a result of the shipping and packaging of the product and OdorKlenz Laundry Additive is effective against those odors.

Can I use this along with vinegar in my wash?

We do not recommend that as our OdorKlenz Laundry Additive will want to neutralize the vinegar effectively canceling the benefits they each offer out.

Will the OdorKlenz Laundry Additive remove musty smells from my front load washer?

Yes with repeated use the product will work on those odors. Additionally, we do make a Washing Machine Deodorizer Product for that application.

Can I use the OdorKlenz Laundry Additive in a High-efficiency (HE) washing machine?

Yes. With the wide range of options available on newer HE machines, please make sure that any pre-rinse settings are turned off. Some machines do a very quick rinse of the tub at the beginning of the cycle and we don’t want our product to be rinsed out before it has a chance to work.
