To wash swimwear and beach clothes well, you need to deal with three things home laundry rarely faces: salt water, sunscreen and humidity. Salt stiffens fabric and fades colour, sunscreen leaves yellow marks, and humid air stops clothes from drying so they start to smell. Handle those three and your clothes will stay fresh for the whole trip.
Why beach clothes wear out so fast
When seawater dries, salt stays trapped in the fibres. Over time swimwear loses its stretch and bright colours fade. Sunscreen contains oils and ingredients that can leave yellow marks on white fabric, especially around collars and shoulders. And wet clothes sealed in a bag will smell musty after a single night.
What to do as soon as you're back from the beach
- Rinse swimwear and sandy clothes in fresh water as soon as you can.
- Press out water by rolling them in a towel instead of wringing hard.
- Hang them somewhere airy, out of harsh direct sun for coloured swimwear.
- If you can't wash them yet, keep wet items in a separate bag away from dry clothes.
What not to put in the dryer
A dryer is the fastest fix in humid weather, but some fabrics don't handle heat:
- Swimwear and activewear with spandex or elastane: heat weakens the stretch fibres, so they sag and lose shape.
- Wool and cashmere: can shrink a full size after one hot cycle.
- Underwired or padded tops: wires bend and padding warps.
- Beads, sequins, metallic prints: they loosen, peel or melt.
- Anything with sunscreen marks still on it: heat sets the stain, so wash it out first.
Reading the dryer symbol on the label
The tumble-dry symbol is a square with a circle inside. One dot means low heat, two dots medium, three dots high. A cross through it means don't tumble dry. A square with a horizontal line inside means dry flat; vertical lines mean hang to dry.
When to use a laundry service
After a few beach days, sending clothes to a by-the-kilo laundry is usually faster and cleaner than hand-washing in your room. Just keep the no-dryer items separate and point them out. In Duong Dong, NightGo Laundry washes, dries and folds for 45,000₫ per kg (about US$1.75), open 24/7, ready in 3–4 hours (express 55,000₫/kg in 1–2 hours).
FAQ
Can swimwear go in the washing machine?
Yes, on a gentle cycle with cool water. Avoid hot drying, which damages the stretch fibres.
How do I remove sunscreen stains from a white shirt?
Treat them early with dish soap or concentrated liquid detergent, leave it a few minutes, then wash. Don't tumble dry until the mark is gone.
Why do clothes dried in a hotel room smell?
Humid air makes them dry very slowly, giving bacteria time to cause odour. Drying in a breeze or in a machine solves it.
