The Ultimate Guide to Washing Your Gym Workout Clothes  

Gym clothes are your workout essentials, built to wick sweat, stretch comfortably, and endure countless cycles of wear. However, without proper care, they can start smelling bad, lose their stretch, or even break down faster than they should.

That’s why washing them correctly is crucial to maintaining their quality. In this guide, we’ll walk you through the best ways to keep your gym clothes fresh, odour-free, and long-lasting.

Why Gym Clothes Need Special Care

Your gym clothes may look sturdy, but their fabric composition requires special attention. Unlike regular cotton garments, most activewear is made from synthetic fabrics like polyester, nylon, and spandex, which are great for wicking sweat but can trap odours and bacteria if not cleaned properly.

These materials are engineered for performance but tend to hold onto oils from your skin, deodorant, and other grime. Over time, this buildup can lead to unpleasant smells becoming trapped and make it harder for your clothes to breathe. The key to keeping your workout clothes in top shape lies in a strategic but easy washing routine.

Step-by-Step Guide to Washing your Sportswear

Step 1: Separate Your Activewear

It’s tempting to toss all your laundry into one load, but sports clothes should be washed separately. This prevents their lightweight, synthetic materials from tangling with heavier fabrics, which can cause pilling or even damage. Additionally, separating your activewear helps preserve its colour and structure since workout clothes are often more delicate than cotton or denim.

Step 2: Pre-Treat Stains and Odours

Whether it’s sweat stains under the armpits or stubborn odour in your leggings, pre-treating these areas will make a big difference in your laundry results. Use an enzyme-based detergent or a natural pre-treatment, such as white vinegar or baking soda. These solutions help break down sweat and oils that cling to synthetic fabrics.

Step 3: Choose the Right Detergent

This is where many people go wrong. Using conventional detergents can leave residue on your gym clothes, making them stiff and even trapping odours. Instead, opt for Sheet Yeah’s eco-friendly detergent sheets, which are free from harsh chemicals and ideal for sensitive skin. These detergent sheets dissolve completely in water and won’t coat your clothes in harmful residue.

Step 4: Select the Proper Wash Settings

For gym clothes, the washing machine’s gentle cycle is your best friend. Cold water is also essential since hot water can break down synthetic fibres over time. Make sure to use a low-spin cycle to avoid damaging the elasticity of your workout gear. Over-spinning can stretch out your clothes, reducing their lifespan. 

Step 5: Drying Tips to Extend Lifespan

High-heat drying is the fastest way to ruin your activewear. Synthetic fibres like spandex and polyester can shrink or lose their stretch when exposed to excessive heat. Instead, air dry your gym gear by laying it flat or hanging it in a well-ventilated area. If you must use a dryer, select the lowest heat setting possible.

Common Mistakes to Avoid When Washing Activewear

Using Fabric Softeners

Fabric softeners are a no-go for gym clothes. They leave a coating on synthetic fibres that can trap sweat and bacteria, leading to persistent odours. Skip the fabric softener and let your activewear’s natural breathability shine through. 

Overloading the Washing Machine

Cramming too many items into the washer not only makes it harder for your clothes to get fully clean but also increases friction, which can cause pilling and wear. Give your clothes space to move freely in the drum.

Waiting Too Long to Wash

After a sweaty workout, bacteria start to multiply on your clothes almost immediately. If you leave your dirty workout clothes in a laundry basket or gym bag for too long, those bacteria can cause the odours to set, making them much harder to remove.

How Often Should You Wash Your Gym Clothes?

A common question is: "Do I really need to wash my gym clothes after every workout?" The answer depends on the intensity of your exercise and the fabric of your clothes. If you’ve had a light workout and haven’t sweated much, you might be able to get away with airing out your gym gear and re-wearing it.

However, after intense workouts where you’ve sweated a lot, it’s best to wash your gym clothes right away. Allowing sweat to sit on the fabric can lead to bacteria buildup and stubborn odours that are harder to get rid of over time.

Final Tips for Maintaining Fresh Gym Clothes

• Use natural deodorisers: Add white vinegar or baking soda to your wash cycle to eliminate odours naturally.
• Avoid plastic bags: Don’t store sweaty gym gear in plastic bags. This creates a humid environment where bacteria thrive. Instead, air them out before washing.
• Turn clothes inside out: Washing gym clothes inside out protects the fabric and ensures that the inside, which has absorbed most of the sweat, gets thoroughly cleaned.
• Use a wash bag: Wash bags help protect delicate or stretchy fabrics from getting caught or tangled in other garments helping them last longer

FAQs About Washing Gym Clothes

1. How often should I wash my activewear?

Ideally, to keep your activewear looking and smelling its best it should be washed after every workout, especially if you’ve sweat a lot. Letting sweat sit in the fabric can lead to bacteria buildup and stubborn odours that are hard to remove and no one wants smelly gym clothes. 

2. What’s the best laundry detergent to use for gym clothes?

It’s best to use a detergent that is specifically formulated for synthetic fabrics or an eco-friendly detergent like Sheet Yeah! that is free from harsh chemicals. Avoid using heavy-duty detergents, as they can leave residue that traps odours in the fabric.

3. Can I use fabric softener on gym clothes?

No, you should avoid using fabric softener on gym clothes. It coats synthetic fibres, making it harder for them to wick moisture and can trap odours. Instead, use a cup of white vinegar in the rinse cycle to help soften and deodorise your clothes naturally.

4. What temperature should I wash workout clothes in?

Always wash gym clothes in cold water. Hot water can damage the synthetic fibres that make up most activewear, leading to a loss of elasticity and faster breakdown of the fabric.

5. How do I get rid of the smell in my workout clothes?

To remove odours, pre-treat your gym clothes with a cup of baking soda or enzyme-based detergent. These break down sweat and oils that cause odour. Make sure you wash your clothes in cold water and air dry them for the best results.

6. Can I put my gym clothes in the dryer?

It’s best to avoid using the dryer for gym clothes, as high heat can shrink or warp synthetic fabrics. Air drying is the gentlest method, but if you need to use a dryer, set it on low or no heat to minimise damage.

7. How can I prevent my gym clothes from pilling?

Pilling occurs when fabrics rub against each other, creating small balls of fibre. To prevent this, wash your gym clothes inside out on a gentle cycle, and avoid washing them with rougher materials like jeans or towels. A wash bag will help prolong the life of your clothes by preventing unnecessary stretching. 

8. Can I wash my gym shoes with my workout clothes?

It’s not recommended to wash gym shoes with your clothes. Shoes can be too rough on delicate activewear fabrics, causing them to pill or tear. If your gym shoes need cleaning, it's best to wash them separately by hand.

9. Why do my gym clothes smell bad even after washing?

If your gym clothes still smell after washing, it could be due to detergent buildup or trapped bacteria. Try soaking them in a mixture of white vinegar and water before washing or switch to an eco-friendly detergent that fully rinses out, like Sheet Yeah!

10. Is it okay to re-wear gym clothes if they don't smell?

If you haven't sweat heavily, you may be able to re-wear gym clothes once. However, bacteria from sweat can still grow on the fabric even if it doesn't smell right away, so it’s generally better to wash them after every use to maintain hygiene.
