Washing summer clothes: a practical guide for the warm season

Summer is the season of light fabrics, bright colours and more sweat. Clothes are worn more often and washed under harder conditions (sweat + sunscreen + sand = a complex mix). And then there is swimwear, which calls for completely different care. In this article — a practical guide for the warm-season wardrobe by garment type, including how to handle seasonal stains and odours.

How summer washing differs

In summer you face several specific issues:

• Increased sweating — 2–3 times more sweat than in winter
• Sunscreen residues — they bond chemically with the fibre and create yellow stains
• Sand in the fibre — damages the washing machine and does not rinse out with normal washing
• Swimming in chlorinated pool water — chlorine damages colours and the fibre
• Sea-salt residues — crystallise in the fibre
• Lighter colours — summer clothes are often pastel or bright — more prone to fading

General rules for summer washing

These rules apply to almost all summer clothes:

1. Wash more often — in summer, a sweaty garment after one day already needs washing. Not like in winter, when you can wear something several times.
2. 30 °C is optimal — protects colours (summer clothes are often light and pastel), and cool water does not lock in sweat or sunscreen stains
3. Enzyme detergent — ideal for everyday washing (handles sweat proteins)
4. No fabric softener for sportswear — sportswear is worn often in summer, and softener damages its moisture-wicking properties
5. Quick reaction to stains — summer clothes are mostly light, so stains show up more

Specific summer garment types

Light T-shirts and dresses (cotton, linen)

The core of the summer wardrobe. Washing:

1. 30 °C, enzyme detergent
2. Standard programme for cotton, delicate — for linen
3. Standard dose (25–30 ml)
4. Extra rinse, if you have sensitive skin
5. Air-drying is the best strategy (clothes dry quickly in summer)

Linen specifics: it creases a lot, so ironing while damp helps. For label symbols, see our guide to washing symbols.

Swimwear

A category of its own — chlorine, salt water, sunscreen + UV impact on the fibre. Strategy:

1. AFTER EVERY swim — rinse in cold water (removes chlorine / salt)
2. Never put a wet costume in a plastic bag — mould develops within hours
3. Weekly washing in cold water with a delicate detergent (NOT enzyme — Lycra and Spandex are sensitive to proteases)
4. NEVER in the dryer (heat damages elastane fibres)
5. NEVER in direct sun (UV damages elastane)
6. Dry in the shade, hung vertically

The typical lifespan of swimwear is 2–3 seasons. After that, the elastane fibre naturally loses its properties.

Sandals (canvas, fabric)

Many summer sandals have a textile upper that needs washing:

1. Remove the insoles (wash separately)
2. Mechanically remove sand from the fibre (with a brush)
3. Wash in a laundry bag at 30 °C with enzyme detergent
4. Dry in a well-ventilated area (not in the sun — it can damage leather elements)
5. Hold the shape with crumpled newspaper

Summer hats and sun hats

Most cannot be machine-washed:

• Straw hats — only dry cleaning with a brush, a damp cloth on the surface
• Canvas summer hats — can be hand-washed in cold water and dried flat
• Caps with a peak — handle carefully, the peak (inner cardboard) can deform in water

Sunglasses (microfibre cleaning cloths)

Microfibre cleaning cloths for glasses are washed by hand in cold water with a mild detergent — without softener (it coats the microfibre and ruins its properties).

The main summer stains

Sunscreen stains (yellow / orange)

Probably the most annoying summer stain. Sunscreens contain mineral pigments (zinc oxide, titanium dioxide) and an oil base:

1. React within 1–2 hours (the sooner the better)
2. Blot the surface with a dry towel
3. Apply a generous amount of dishwashing liquid (a strong surfactant)
4. Massage gently for 2–3 minutes
5. Leave for 30 minutes
6. Wash at 40 °C with enzyme detergent

For tougher cases — the same approach as in our oil-stains guide applies (sunscreens are oil-based).

Sweat stains

The main summer issue, especially yellow stains forming on white shirts. More in our sweat-stain guide.

Sand and dirt from the beach

Strategy:

1. First, MECHANICALLY remove the sand thoroughly (brush, shake out)
2. Never put sandy clothes straight into the machine — sand can damage the pump
3. Cold pre-rinse (without detergent) first — to remove the remaining sand
4. Then a normal wash

Sea-salt residues

After a swim in the sea, the garment becomes "cardboard-like":

1. Soak in cold water for 30 minutes — the salt crystals dissolve
2. Wash at 30 °C with enzyme detergent
3. Extra rinse

Grass and berry stains

Summer is the season of grass and berries. The grass-stain guide is in a separate article.

Summer odour problems

In summer clothes more often smell after a few wears — even after washing. Reasons:

• Bacteria grow faster in warmth
• Sweat volume is higher
• Laundry absorbs more environmental smells (the beach, a restaurant terrace)

Solutions:

1. Vinegar soak (50 ml + cold water) for 30 minutes before washing
2. Essential oils (tea tree, eucalyptus) added to the machine — antimicrobial effect
3. Sun drying — a natural disinfectant
4. The washing machine itself must be clean — see our guide to washing-machine care

March/April routine

As the summer season starts, winter clothes go into storage — see our guide to winter clothes. Summer clothes come out of storage:

1. All summer clothes are washed before the first wear — to remove storage dust and smell
2. Check them for mould, moth damage and stains
3. Sunlight airs them and disinfects further

The economics of summer washing

You wash more often in summer, but:

• 30 °C washing — saves electricity, especially compared with winter 60 °C cycles
• Air-drying — free (instead of a tumble dryer)
• Smaller dose (lightly soiled clothes) — saves detergent

In practice, summer months can be cheaper in electricity even though you wash more often. More on cold washing — our low-temperature guide.

Specifics by setting

Travelling / on holiday

Practical advice:

• Take a travel-size detergent
• Rinse swimwear in cold water after every use
• T-shirts can be washed in the hotel shower with warm water
• Dry overnight, indoors with a fan (not in the room where you sleep — humidity)

Gardening / active work

Heavier soiling, sweat, sometimes grass stains:

• Separately from everyday clothes
• Pre-soak with vinegar + detergent for 30 minutes
• 40 °C standard
• A full dose of enzyme detergent

Frequently asked questions

Do you really need to wash a swimsuit after every use?

Rinse — yes, in cold water, to remove chlorine / salt / sunscreen. A full wash — not every time, perhaps once a week. But a cold rinse after every swim is mandatory.

Is sun-drying coloured clothes bad?

For coloured items — yes, prolonged sun fades colours. For whites — fine (UV brightens naturally). Optimally: dry coloureds in the shade, whites in the sun.

How do you protect light shirts from sweat stains?

The best combination: aluminium-free antiperspirants + sweat pads + frequent washing (after one day's wear). More in our sweat-stains guide.

My favourite T-shirts went yellow in one season. What happened?

Most likely — the antiperspirant aluminium + sweat combination + incorrect washing (too hot). Yellow sweat-stain prevention and removal is its own topic.

Does dry shampoo work on summer hats?

It works a little for removing oil (leave for 5 minutes, then brush off). But — a full clean is still needed. Dry shampoo only stretches the time until the next wash.

Summary

Summer washing calls for a different approach than winter: more often but at lower temperatures, with extra attention to sweat, sunscreens and specific summer situations (beach, pool, sport). Swimwear is its own category with special care. Ecozyme enzyme detergent is suitable for almost all summer clothes (except swimwear because of Lycra/Spandex sensitivity).
