How to Get the "Gym Funk" Out of Your Activewear

Hyperloop Laundry Delivery • October 14, 2025

You spent a lot of money on your high-performance leggings, moisture-wicking shirts, and sports bras. But after a few months of heavy workouts, you might notice something: they still smell "funky" even after they’ve been washed. This happens because synthetic fabrics like spandex and polyester are designed to repel water but attract oil (sebum) from your skin. Standard laundry habits can actually trap bacteria inside these fibers. Here is how to save your gym gear and keep it smelling fresh.

1. Never Use Fabric Softener

This is the #1 mistake people make with activewear. Fabric softener works by leaving a waxy coating on fibers to make them feel soft.

The Problem: That coating clogs the "pores" of moisture-wicking fabric.

The Result: It locks in sweat and bacteria, creating a "permanent funk" that grows every time you workout. It also destroys the fabric’s ability to pull sweat away from your skin.

2. The "Pre-Soak" Vinegar Solution

If your gym clothes have a lingering odor, they need a "strip" wash.

The Hack: Soak your gym clothes in a sink with one part white vinegar and four parts cold water for 30 minutes before washing. The acid in the vinegar breaks down the body oils and detergent buildup that trap odors.

3. Wash Them Inside Out

Most of the "gunk" (sweat, dead skin, and bacteria) is on the inside of your leggings and shirts. By turning them inside out before tossing them in the wash, you give the water and detergent direct access to the source of the smell. This also protects the outer finish of your expensive gear from pilling.

4. Don't Let Them Marinate

We’ve all been guilty of leaving a gym bag in the car or a pile of wet workout clothes in the hamper. This is a breeding ground for mold and mildew.

Pro Tip: If you can't wash your gym clothes immediately, hang them up to air dry before putting them in the laundry basket. Never leave them bunched up and wet.

5. Skip the Heat

Heat is the enemy of spandex and elastic. High dryer temperatures break down the "stretch" in your leggings, leading to those annoying little white fibers (elastics breaking) and a loss of shape.

The Rule: Always wash in cold water and air dry or use the "Extra Low" heat setting on your dryer.

6. Use the Right Amount of Detergent

It’s tempting to use "extra" soap for extra-stinky clothes, but this actually makes the problem worse. Excess detergent doesn't rinse out; it builds up in the fabric and creates a "food source" for bacteria. Stick to the recommended amount or use a specialized "Sport" detergent.
