5 Best Detergents for Workout Clothes: Get the Sweat Away

Workout clothes are the heroes of our active lives that support us through the grinding gym sessions. But our honorable gym clothes often bear the pressure of our efforts, ending up saturated with sweat, body oils, and stubborn odors that regular laundry detergents just can't seem to conquer. The synthetic fibers designed to wick moisture away from our bodies also have a notorious habit of trapping these unwelcome elements, leading to that distinct gym smell that lingers even after a wash.

This persistent problem is annoying and can impact the longevity of your activewear. Trapped residues can break down fabric elasticity, diminish moisture-wicking capabilities, and even cause skin irritation over time. Standard detergents are great for everyday cottons, just lack the enzymes needed to deep clean synthetic workout fabrics.

Forget masking odors with heavy perfumes; the goal is to eliminate them at their source. This guide will walk you through the best detergents for workout clothes, specifically formulated to tackle the unique challenges posed by sweat-soaked athletic apparel. And for those times when you'd rather leave the dirty work to the pros, remember services like ByNext offer convenient solutions like their wash and fold laundry service to keep your gym clothes in pristine condition.

Why Regular Detergents Fail on Workout Clothes

Workout clothes are made from synthetic fabrics such as spandex, polyester, and nylon because these are designed to wick away moisture from the body. However, their tightly woven and hydrophobic (water-repelling) structure creates a perfect environment for sweat and bacteria to get trapped. These fabrics tend to attract and hold onto the oily components of sweat, which then become a breeding ground for odor-causing bacteria. 

The standard-best laundry detergent formulations are primarily designed to clean natural fibers and struggle to penetrate these synthetic materials effectively to break down and eliminate the embedded oils and bacteria. This is why a regular detergent for sweaty clothes often falls short, leading to persistent odors even after washing, highlighting the need for the best detergent for workout clothes.

Let the Pros Sweat It—We’ll Handle the Wash!

Sweat, Bacteria & Synthetics

• Synthetic fabrics trap sweat and odor deep inside.

• Regular detergents can't fully break down bacteria.

• Moisture-wicking materials hold onto grime.

• Bacteria cause lingering smells even after washing.

• Oils from skin mix with sweat, making stains more challenging.

• Regular detergents leave residue on technical fabrics.

• Requires formulas made for activewear.

Because of These Washing Mistakes

• Using hot water can damage elastic fibers.

• Overloading the machine limits proper cleaning.

How We Picked the Best Workout Detergents

Selecting the best workout detergents requires a meticulous evaluation process that goes beyond just a pleasant scent.  Our assessment is focused on several key criteria to make sure each detergent performs well on the unique challenges. 
We carefully examined each detergent's ability to combat germs and sweat that had been ingrained, differentiating between formulations that eliminate odors at the molecular level and those that only cover them up. Delicate technical fabrics like spandex, nylon, and polyester are frequently used in workout attire; these materials can be harmed by harsh chemicals or extreme heat. Beyond functionality, we also considered eco-friendliness, assessing detergents for biodegradable ingredients, sustainable packaging, and the absence of harmful chemicals like phosphates, dyes, and artificial fragrances. This included examining popular eco brands that have proven effective without compromising on cleaning power.
