How to Care for Gym Clothes: Washing, Drying and Storage

The symbols on a care label tell you which treatments the specific garment is designed to tolerate. The temperature shown in the washing symbol represents a permitted maximum temperature — not a recommendation to wash as hot as possible.

Drying, ironing and professional textile care are also indicated separately.

In practice, this means:

• If the label specifies a maximum of 30°C, that temperature should not be exceeded.
• If tumble drying is crossed out, the garment should not go into a tumble dryer.
• If only low-temperature ironing is permitted, that still applies even if the fabric itself feels robust.
• Product-specific instructions such as “wash inside out” or “do not iron print” should also be followed.

General advice found online can be useful for orientation, but it does not replace the instructions for the individual garment.

Sweaty workout clothes should ideally not remain crumpled inside a closed gym bag for hours. Moisture, warmth and residues from sweat and skin oils create conditions in which noticeable odors can develop.

If you cannot wash the garment immediately, spread it out or hang it somewhere it can dry first. Only place it in the laundry basket once it is dry.

This will not automatically remove odor, but it avoids keeping the garment unnecessarily damp and enclosed for an extended period.

Research following fitness sessions indicates that odor development is associated with microorganisms and textile type. The findings cannot be applied directly to every individual garment, but they support the point that odor is more complex than simply “sweat trapped in fabric.”

Using more detergent is not automatically the answer to persistent odor. Detergent should be dosed according to the manufacturer’s instructions, water hardness, load size and level of soiling.

Overloading the washing machine can also prevent clothes from moving and rinsing effectively.

A short preparation before washing can reduce unnecessary mechanical stress.

• Empty all pockets.
• Close zips and hook-and-loop fasteners so they do not rub against other textiles.
• Turn printed T-shirts inside out.
• Separate light, dark and strongly colored garments according to normal laundry practice.
• If necessary, place delicate embroidered garments in a laundry bag to reduce the chance of snagging on hooks, zips or other closures.
• Do not overload the washing machine.

Printed shirts are commonly washed inside out because this exposes the printed outer surface to less direct friction against other garments and the washing-machine drum.

This does not prevent wear completely, but it can reduce unnecessary mechanical stress on the visible print surface.

Always start with the care label.

For normally sweaty, colored workout shirts, the lowest permitted temperature that cleans the garment effectively is often a sensible starting point.

For example, if a shirt is approved for washing at either 30°C or 40°C, the lower temperature may be sufficient for normal wear. For heavier soiling, the higher permitted temperature may be appropriate.

The key word is permitted: general advice should never assume that a garment can tolerate more or less than the manufacturer specifies.

The washing cycle also affects mechanical stress.

Easy-care or delicate cycles may move and spin garments differently from more intensive standard cycles. Whether that is necessary depends on the fabric, construction and care instructions.

A robust cotton T-shirt may be suitable for a standard cycle, while more delicate constructions may benefit from gentler treatment.

More detergent does not automatically produce cleaner clothes. Follow the detergent manufacturer’s dosing instructions and account for load size and water hardness.

A tumble dryer combines heat with repeated mechanical movement. Both can place greater stress on fabrics and decorative finishes than calm air drying.

A garment should therefore only be tumble dried if the care label allows it.

When air drying, a few simple steps can help:

• Remove the garment from the washing machine promptly.
• Shake it out gently.
• Reshape the collar, hem and sleeves without pulling aggressively.
• Allow it to dry with sufficient air circulation.
• Consider drying particularly heavy or stretchy knitted garments flat so their wet weight does not pull excessively on the shoulders or length.
• If using a hanger, choose one wide enough to avoid pronounced pressure points.

Avoid strong direct heat if it is not permitted by the care instructions. This also applies to radiators and very hot surfaces.

Printed and embroidered decorations behave differently because they are constructed differently.

With a print, the decorative layer sits on or within the textile surface. Embroidery, by contrast, is formed from thread secured to the fabric with stitches, backing and — where necessary — stabilizing materials.

For printed garments, common practical measures include:

• washing inside out,
• avoiding direct ironing over the print,
• avoiding unnecessary wringing,
• only tumble drying when specifically permitted.

With embroidery, mechanical snagging is particularly relevant.

Zips, hooks or rough hook-and-loop fasteners can catch on embroidery threads. For more delicate pieces, a laundry bag can provide an additional barrier.

Visible loose threads should not simply be pulled out, as doing so may loosen surrounding stitches.

The specific care instructions for the garment remain decisive.

Shrinkage can be influenced by several factors, including fiber type, fabric construction, previous textile treatments, moisture, heat and mechanical movement.

That is why two shirts that look similar may not behave identically during washing and drying.

Appropriate care can reduce the risk of unwanted changes, but it cannot guarantee that a garment will never change at all.

Useful precautions include:

• never exceeding the permitted wash temperature,
• avoiding tumble drying when it is not allowed,
• gently reshaping the garment after washing,
• assessing changes across several wash cycles rather than assuming that a single small measurement difference proves a particular cause.

For standard T-shirts, neat folding is a straightforward option.

Particularly heavy shirts or hoodies can develop pressure marks around the shoulders when left on narrow hangers, or their own weight may affect how they hang over time.

A wider, appropriately shaped hanger can reduce this risk. Alternatively, these garments can simply be folded.

Lighter shirts can also be hung, provided the hanger does not distort the shoulder area.

Regardless of the method:

• only store garments once they are fully dry,
• avoid permanently compressing them into an overcrowded drawer,
• avoid sharp folds directly through prints if they create a pronounced crease,
• store clothes clean before longer periods of storage.

• Leaving sweaty clothes damp in a closed gym bag for long periods.
• Exceeding the maximum temperature stated on the care label.
• Using a tumble dryer when the care symbol prohibits it.
• Applying high direct heat to printed areas.
• Washing delicate garments together with open zips or hook-and-loop fasteners.
• Using more detergent than recommended.
• Aggressively pulling or wringing a garment while it is wet.
• Letting general online advice override the specific care instructions.

Fabric softener should not be universally recommended or prohibited for all gymwear.

Some manufacturers specifically advise against it for certain performance fabrics, while other textiles may have different care requirements. The product-specific care instructions remain the deciding factor.

This article provides practical guidance for washing, drying and storing different types of gymwear.

It cannot account for every fiber blend, textile treatment or decorative finish used in a specific product.

The care instructions on the individual garment therefore always take priority.

Good clothing care is not based on one universal rule. It starts with understanding the individual garment, its care label and its decorative finishes.

The NINTAI | 忍耐 Men’s Gym T-Shirt combines 200 g/m² cotton, an Athletic Fit and High Density Screen Printing. The product page and garment care label provide the specific care instructions intended for that product.

If this knowledge helps you look after your clothes more thoughtfully, the article has done its job — regardless of which brand you buy.
