How to wash bikinis and swimsuits without damaging the fabric

Why does swimwear need special care?

Bikinis, swimsuits, and swimming trunks are designed for contact with water, sun, and movement. However, this doesn't mean they can be washed like any other piece of clothing.

After a day at the beach or pool, these fabrics accumulate salt, chlorine, sand, sunscreen and sweat. Even when the garment appears clean, some of these residues remain in the fibres and, over time, can affect the colour, elasticity and shape of the part.

Small errors, such as using hot water, wringing out the fabric, or leaving the garment damp for too long, can speed up wear and cause your bikini or swimsuit to lose its original fit.

In this article, Blue Lavandarias explains how to wash and care for beachwear simply, helping to preserve the fabric and prolong the durability of items.

How to wash bikinis, swimsuits and trunks after use

The way you treat your swimwear right after use can make a difference to its durability. Small precautions can help prevent premature wear, stains, and changes to the fabric's texture.

Rinse under cold water after the beach or pool

After wearing a bikini, swimsuit or shorts, it is best to rinse the garment in cold water as soon as possible. This rinse helps to remove some of the residues left on the fabric after contact with the sea, the pool or sunscreen.

Even when the garment appears clean, some of these residues remain present in the fibres. Over time, stains, odours, and loss of elasticity can occur.

This care does not replace a more thorough wash, but it prevents dirt from accumulating until you get home. Whenever possible, use cold or lukewarm water and avoid hot water, especially in items with elastane, linings, straps, or more delicate finishes.

💡 Blue TipIf sand gets trapped in the lining, seams, or elasticated areas, leave the garment in clean water for a few minutes before washing with detergent. This care helps to loosen debris without creating unnecessary friction on the fabric.

Choose hand wash

For most bikinis and swimsuits, Washing by hand remains the safest option. This method allows for better temperature control, reduced friction, and prevention of deformation during washing.

When hand washing, follow these steps:

  1. Fill a container with cold or lukewarm water, avoiding hot water, which can affect the fabric's elasticity.

  2. Add a small amount of mild detergent, suitable for delicate items. If you are unsure about which type of detergent to choose, A DECO Proteste explains the differences between each category and when to use each one..

  3. Immerse the piece and move it gently in the water for a minute or two, without rubbing or wringing the fabric.

  4. Rinse well until remove all detergent residue.

  5. To remove excess water, Wrap the item in a dry, clean towel., and press carefully, without twisting.


If you choose to use a machine, select a delicate programme with cold water and a gentle spin. Place the items inside a mesh laundry bag and avoid mixing them with heavy items, such as jeans and towels, which increase friction inside the drum.

💡 Blue TipAlways check the label before washing. Some bikinis or swimsuits with padding, underwires, or decorative applications have specific restrictions. The textile care symbols help you understand exactly what each item can tolerate.

How to dry and store without damaging the fabric?

After washing, Leave the swimwear to dry in the shade, in a well-ventilated spot.. The tumble dryer is not recommended, as excessive heat can affect elastic fibres and compromise the garment's fit.

Direct sunlight should also be avoided. Although it accelerates drying, it can cause fading, especially in bright colours and prints.

Whenever possible, Leave the bikini or swimsuit to dry flat.. Hanging the garment while it's still damp by the straps or elasticated areas can cause the weight of the water to stretch the fabric and alter its original shape.

Before storing, always confirm that the item is completely dry. Even small amounts of moisture can cause unpleasant odours, especially if the laundry is kept folded in drawers, boxes or bags.

While tidying, Avoid leaving items rolled up or compressed amongst other clothes. Store them folded carefully, in a dry, airy place away from direct light, to prevent deformation and dampness.

How to remove sunscreen stains from swimwear?

Sunscreen stains are common on bikinis and swimsuits, especially in areas where the product accumulates more easily, such as straps, linings and seams. 

As many sunscreens have an oily base, these residues can easily adhere to the synthetic fibres used in these types of garments, such as polyamide, nylon or elastane.

In many cases, stains only become visible after the garment has dried, leaving yellowish, oily, or darker areas on the fabric. For this reason, when you notice a stain, it is important to treat the affected area before proceeding with a full wash.

Rinse the stained area with cold water and apply a small amount of mild detergent directly onto the fabric. Leave it to work for 15 to 30 minutes, without rubbing.

Avoid bleach, stain removers and harsh detergents or hot water, as they can damage the fibres and worsen the stain. When the sunscreen is still fresh, this care is usually enough to make it easier to remove during washing.

Frequently asked questions about washing bikinis and swimsuits

Is it necessary to wash a bikini or swimsuit after each use?

Yes. Even when the garment appears clean, fabric accumulates salt, chlorine, sweat, sand, and/or sunscreen. Rinsing and washing after use helps to preserve the garment's elasticity, colour, and durability.

Can I keep my bikini or swimsuit still damp in my beach bag?

For a short period, it usually doesn't pose a problem. Still, the most important thing is not to leave the garment wet and closed for many hours. As soon as possible, rinse the bikini in cold water and avoid leaving it crumpled in your bag or rolled up in your towel until the next day.

Can chlorine and seawater damage fabric?

Yes, especially when the residue remains on the part for a long time.

Chlorine is particularly aggressive towards elastane, as it weakens the fibres and speeds up the loss of elasticity. Salt, on the other hand, can have a similar abrasive effect when it dries onto the fabric without being rinsed out.

Can I soak the bikini for several hours?

It is not recommended. Leaving the garment to soak for too long can weaken the fibres, wear out the elastane, and cause colour transfer between fabrics.

Can I use normal detergent to wash bikinis?

Yes, as long as it is used in small quantities and does not contain whitening agents or anything too harsh.

Can I use fabric softener on swimwear?

It is not the most recommended. In garments with elastic fibres, fabric softener can leave residue on the fabric and compromise elasticity over time.

Why is regular cleaning important?

Carpets and rugs make the home more cosy, reduce noise, insulate against the cold and add comfort and aesthetics to every room. But they also accumulate dust, mites, animal hair, stains and odours that don't disappear just by vacuuming or shaking them out.

Even with a quick cleaning at home, The fact is that much of the dirt remains trapped inside the fibres and, over time, can cause allergies, bad odours and premature wear. That's why, in addition to routine cleaning, it's essential to plan deep cleans at an appropriate frequency.

A Directorate-General for Health recommends sanitising carpets and rugs at least twice a year in ordinary homes. However, this interval varies depending on the type of item, daily circulation, the characteristics of the house and the presence of animals.

In this article, Blue Lavandarias explains the factors that influence the ideal frequency, the recommended intervals and the advantages of professional washing.

How do you define the ideal washing frequency?

The right frequency for washing carpets and rugs always depends on the reality of each home. There is no single interval, it depends on the type of item, the room it's in and daily use, or even the presence of pets.

Below you will find the essential aspects to consider:

Carpets: what's the difference?

Although we often use the terms synonymously, carpets and rugs don't have the same behaviour or require the same attention.

Carpets are mobile items that are easy to shake out and vacuum. Due to their occasional use in entryways, kitchens or dining areas, they tend to pick up stains and odours quickly. However, as they move around frequently, dirt tends to remain more on the surface.

Carpets, on the other hand, are fixed to the floor and cover larger areas such as living rooms, corridors or bedrooms. For this reason, they accumulate dust and mites inside the fibres more intensely. Even when they look clean, they need regular professional washing to maintain the comfort and hygiene they give to the home.

Factors influencing washing frequency

Not all homes are the same and neither are carpets. The ideal cleaning frequency depends a lot on daily use and a few habits that make all the difference to the fibres.

Houses and busy spaces

In homes with a lot of traffic, frequent visitors or children, carpets accumulate dirt more quickly.

The dirt we carry in our shoes gets trapped between the fibres and, over time, becomes more difficult to remove.

In commercial spaces where there is constant traffic, regular professional cleaning is essential to maintain hygiene and durability.

Fabric type and colour

Carpets made of natural fibres, with long pile or in light colours reveal dirt more quickly.

In addition, they are more sensitive to wear and tear and clearly benefit from more frequent and careful cleaning.

Pets

If you have cats or dogs, you know how carpets “store” everything: hair, odours, stains and even dirt from paws.

In these cases, professional washing is recommended every 3 to 6 months to ensure hygiene and avoid persistent odours.

Smokers at home

Smoke adheres easily to the fibres and creates odours that a simple hoover won't remove.

The more exposure to smoke, the more regular your professional cleaning should be.

Allergies or respiratory sensitivity

For families with allergies, rhinitis or respiratory sensitivity, carpets need extra care.

Ideally, you should plan professional cleanings every 3 to 6 months to reduce dust mites and improve the air quality inside your home.

Recommended intervals for professional washing

  1. For normal use, professional washing is ideal between 12 and 18 months. This is the right interval for homes without a lot of traffic or animals.

  2. In cases where the carpet is in an area with heavy traffic, such as corridors, entrances or living rooms, it is recommended to reduce this interval to around 6 months, as dirt accumulates much more quickly.

  3. If you have pets, you need to be even more careful: ideally you should wash every 3 to 6 months to control odours, dander and stains that get into the fibres.

  4. Families with allergies, small children or smokers benefit from the same interval: washing every 3 to 6 months helps to improve air quality and keep the environment healthier.

  5. Finally, in commercial spaces, where use is intensive and continuous, the recommendation is to deep clean every 3 months, ensuring hygiene and good presentation.

3 Reasons for regular professional cleaning

Deep hygiene that goes beyond vacuuming

Even when they look clean, carpets accumulate fine dust, dust mites, animal hair and particles that are trapped inside the fibres, which the hoover cannot remove.

By carrying out specialised washes on a regular basis, you are improving your home's indoor air quality and contributing to a healthier environment that makes a difference to your family's daily well-being.

Prevent wear and tear and extend the life of your carpets

With daily use, carpets accumulate dirt which, even if invisible, wears down the fibres and changes their texture.

Without regular deep cleansing, they begin to lose their smoothness, shine and colour, becoming duller and areas visibly worn.

By washing professionally at the right frequency, these residues are completely removed. The fibres regain their shape, strength and natural elasticity, the carpet remains soft to the touch and retains its cared-for appearance for much longer.

Prevents stains and mould

When a stain remains on the carpet for too long, it ends up settling into the fibres and becomes much more difficult to remove.

The same goes for humidity: spilled liquids, leftover food or even the presence of animals can generate persistent odours and create the perfect conditions for mould to grow.

Professional washing solves the problem at its source. It thoroughly removes bacteria, accumulated dirt and residues that cause stains and bad odours, leaving your carpet truly clean, sanitised and looking fresh for much longer.

4 Blue tips to keep your carpet spotless on a daily basis

Even between professional cleanings, there are small gestures that help to extend the life of carpets and maintain comfort at home.

1. Vacuum regularly

By vacuuming several times a week, you prevent dust and dirt from accumulating inside the fibres, which makes it much easier to clean professionally afterwards.

2. Treat carpet stains immediately

The sooner you act, the more likely it is that the stain will come out without leaving marks. Remove the excess with a clean cloth and avoid rubbing to avoid spreading the liquid.

3. Leave your shoes at the entrance

One of the biggest enemies of carpets is the dirt we bring in from the street. A simple entrance mat or the habit of taking your shoes off helps to significantly reduce wear and tear.

4. Avoid prolonged exposure to direct sunlight

Intense light can fade colours and weaken fibres. Whenever possible, change the position of the carpet or use curtains to moderate the intensity of the light.

5 Advantages of choosing Blue Lavandarias for a professional wash

1) Expertise and specialised diagnosis

At Blue Lavandarias, we treat each carpet individually because no two pieces are the same. Our team has mastered the characteristics of the different types of fibres and knows exactly how each material reacts during washing.

Before starting the process, we always carry out a technical assessment: we analyse the density, the level of soiling, the sensitivity of the fabric and the stability of the colours. This diagnosis allows us to choose the safest method and guarantee effective cleaning without the risk of damage or changes in texture.

2. Professional equipment for deep cleaning

The depth of cleaning we achieve at Blue is not possible with domestic machines.

Carpets, even the finest ones, become heavy and bulky when wet, and most traditional machines can't handle that weight.

That's why we use high-capacity professional machinery, prepared for the size and density of the carpets and rugs.

This equipment allows you to wash, rinse and dry evenly, completely removing dirt, odours and moisture, which is essential for keeping the garment hygienic and avoiding mould.

3. Suitable products that protect the fibres

The wrong detergents can cause stains, loss of colour, shrinkage or hardening of the fibres, all of which are common problems when washing at home.

At Blue Lavandarias, we select specific products for each type of carpet, balancing effectiveness and softness.

This way, we can remove deep-rooted dirt and persistent odours without damaging the fabric, preserving the colour, texture and natural softness of the fibres.

4. Prevention of damage and premature wear

Much of the damage to carpets is the result of over-aggressive household cleaning methods or inadequate drying.

Excess water, undue friction or the wrong products can deform the piece and shorten its lifespan.

By choosing Blue Lavandarias you avoid this risk altogether. Our processes are designed to protect your carpet at every stage, from washing to drying.

5. Convenience and time saving
