Frequently Asked Questions

Can I use HEX In-Rinse Booster as a standalone detergent?

No, HEX In-Rinse Boosters are designed to be the first fabric-safe performance additives. It’s the perfect compliment to HEX Advanced Laundry Detergent.

Can I use HEX In-Rinse Booster with my traditional detergent?

No. The formulas of the two products are not complimentary. HEX In-Rinse Boosters were designed with an entirely different cleaning chemistry than traditional detergents, and the two would counteract each other. We recommend using Advanced Laundry Detergent and In-Rinse Fabric Booster together.

How do I use this?

Add a dose of HEX In-Rinse Fabric Booster to your machine’s fabric softener receptacle. Visit our directions page for details on how to open and use the fabric booster.

The tag on my clothing says, “do not use fabric softener.” Can I use this?

Yes! Traditional fabric softeners and dryer sheets coat fabric with a wax that ruins the technical features (like sweat-wicking, breathability, etc). HEX Fabric Booster is the first laundry additive safe for synthetic and performance fabrics.

How is this different from other fabric softeners?

Fabric softeners and dryer sheets were created several decades ago, and they haven’t changed much. To get that soft feeling, they leave a wax-like film on the fibers. This wax clogs the fabric, messing with its features.

HEX In-Rinse Boosters were designed with an entirely different chemistry. They’re specially designed to be safe for synthetic and organic fibers. They naturally soften, they're antistatic, and they also add more protection from future odors (when used with a HEX Detergent)

Is HEX tested on animals?

No, HEX never has, and never will test on animals. However, it is animal approved! If you've got beds and blankets with pet odor and stains, HEX can save them!

Is HEX color safe?

Yes! In fact, the active ingredient in HEX should actually provide better color retention than regular additives. Of course we always recommend following the manufacturer’s care instructions. In some cases with lower quality fabrics, you might want to test for color fastness before using HEX.

Is HEX safe to use in a high efficiency (HE) machine?

Yes. HEX is safe to use in all machines, including high efficiency washing machines.

What ingredients are in HEX In-Rinse Fabric Booster?

HEX In-Rinse Fabric Booster (Fresh Clean Scent) is made up of a biodegradable blend of: water, surfactants, fragrance, and preservatives.

    I’m a Hex user for life! (verified owner)

    This stuff is amazing! I’ve previously just used the Hex detergent and I thought my clothes smelled good. I recently washed my Merino wool items with Hex detergent and booster and all I can say is, ‘WOW”! No static cling either. My HE dryer strictly forbids using dryer sheets, so my synthetic and wool items can get pretty charged with static after a tumble in the dryer, especially in the winter months. I couldn’t believe how good my activewear smelled, looked, and felt! I’m a Hex user for life!

    Great product! (verified owner)

    Bought some of this by accident (I thought it was more Hex detergent, which I love), but it’s become a staple in my laundry routine as a result. Smells like green apples, and helps boost the cleaning power of my detergent (put it in during the rinse cycle). If you have a lot of athleisurewear or workout clothing, this will help prevent them from getting stinky and gross. Highly recommended!

    I love this product!

    I noticed my teenager’s clothes were not smelling clean after washing them and wondered if it had anything to do with the material then lo and behold, I see this detergent specifically created for the newer fabrics used mostly in athletic wear. I gave it a try and I am glad I did. Now his clothes aren’t just clean, they smell clean too.

    Makes laundry easier! (verified owner)

    The fabric booster is a plus to the detergent. Makes laundry easier! I used to put other ingredients (ex: vinegar) to remove smell. But not any more…

    No static cling (verified owner)

    Not only does this clean my son’s lacrosse gear, i use it for all my laundry and it comes out clean, fresh and like new. No static cling to worry about with the booster.
    Great product, I would never go back to another detergent again!

    Worked well with my Hex detergent. It adds a nice scent without being overpowering.

    A laundry must

    I use this with the detergent for my workout clothes. No more residual sweaty smell and it maintains the fabric. No fading or balling on my expensive workout clothes.

    It really does knock out the static

    Love it! It really does knock out the static on performance wear and all other fabrics. I just stocked up after trying it. I’m sold for life!

    Finally able to ditch the harmful dryer sheets.

    Until now, I have always used dryer sheets with my performance clothing, even though I know it’s not good for the fabric, because even when using dryer balls, the static cling was unbearable. I was skeptical that an in-rinse additive could really fix the problem, but I decided to give this a try. I love it! The scent is nice (but not overpowering), a welcome addition because I noticed that even when using the unscented version of the Hex detergent, my clothes would be left with somewhat of a funny chemical odor. Most importantly, I’ve ditched the harmful dryer sheets and had no problems at all with static.

    No more dryer sheets/balls/sprays! (verified owner)

    No more dryer sheets/balls/sprays! Simple to use and it does exactly what it promises to do: refreshes the fabric and eliminates all the static. Seriously, I had a load of towels and fleece (static heaven) and when I pulled it out of the dryer there was ZERO static. The light scent is refreshing, smells like green apple to me. Get this booster, and really you should get the detergent too to complete your laundry arsenal.
