How to Wash Workout Clothes with White Vinegar

Workout clothes can hold on to the smell of sweat very easily, even after they’ve been washed. That’s because technical fabrics tend to trap traces of bacteria, deodorant and the skin’s natural oils. As a result, many people look for simple, affordable ways to keep sportswear clean, soft and odour-free without harming the fabric’s stretch - and white distilled vinegar is often suggested as a useful household option.

How to wash workout clothes with vinegar step by step?

Before adding any product, start by separating your gym kit from other laundry - especially towels and heavy cotton items. Next, turn sportswear inside out, as the inner side is where sweat and deodorant are usually most concentrated and hardest to shift.

White distilled vinegar is generally the preferred choice for this kind of wash, as long as it is properly diluted. A straightforward method like the one below can help loosen residue that detergent alone doesn’t always remove, while keeping the fabric’s feel and elasticity intact.

1. Fill a bucket or basin with cold or slightly cool water.
2. Add ½ to 1 cup (120 to 240 ml) of white vinegar for every 4 to 5 litres of water.
3. Stir well, then add the workout clothes already turned inside out.
4. Leave to soak for 20 to 40 minutes, and do not go beyond 1 hour.
5. After soaking, wash as normal with a laundry detergent, ideally using a delicate cycle.

How does vinegar help remove the smell of sweat from clothes?

White distilled vinegar has a mild acidity that helps neutralise odours linked to bacteria in dried sweat. When workout clothes soak in a water-and-vinegar solution, the particles responsible for unpleasant smells tend to lift more easily during washing, without needing very hot water.

To strengthen this effect and reduce the chance of the odour returning quickly, a few everyday washing habits can noticeably improve the final result and keep the fabric smelling fresher for longer.

• Wash as soon as possible: leaving sweaty kit in a bag or laundry basket for days makes the smell set in.
• Don’t overdo the detergent: too much soap can stay trapped in the fibres and contribute to bad odours.
• Avoid very hot water: with gym fabrics, high temperatures can “cook in” the smell.
• Dry in a well-ventilated place: hanging in the shade in an airy spot helps any remaining odours disperse.

Does vinegar soften the fabric without damaging elasticity?

It can help make fibres feel more flexible, particularly when detergent or conventional fabric conditioner has built up. By breaking down those leftovers, the material often feels less stiff to the touch - which is useful for frequently worn leggings, sports bras and dry-fit T-shirts.

Clothing made with elastane, polyamide and other technical fibres needs careful handling so the structure isn’t affected. Using diluted white distilled vinegar in cold or slightly cool water, and sticking to the recommended soaking time, helps prevent damage and keeps the stretch in good condition.

How often should you use vinegar on workout clothes?

You don’t need to add vinegar to every wash, except when the smell is very strong and keeps coming back. For people who train regularly, using it in one wash during the week is usually enough to maintain freshness, as long as items are dried in a well-ventilated place.

You can also save vinegar for times when odour lingers even after a normal wash, alternating it with specialist sportswear cleaning products. This approach helps clothes stay looking good, without a noticeable smell, while preserving durability over time.
