Yes, you can use laundry detergent on swimsuits but ensure that it is a mild detergent small enough to wash your bathing suits. It is also important that you check the care instructions from your swimwear brand so that you do not ruin your suit.
Some laundry detergents are too harsh for the delicate fabric of swimsuits. Swimwear is often made from elastic materials like spandex or Lycra, and these fabrics can be damaged by the strong chemicals found in many laundry detergents.
In this blog post, we will discuss how to properly use laundry detergent on your swimsuit. Stick with me as we explore how to care for your beloved beachwear properly.
Should You Wash Swimsuits With Detergent?
Yes, you can wash swimsuits with detergents. However, it’s crucial to use a mild detergent when washing swimsuits to help prolong their lifespan and maintain their vibrant colors. A harsh detergent can break down the elastic fabric in swimsuits, leading to a loss of shape and a faded appearance over time.
When washing your swimsuit, avoid using bleach or other strong cleaning agents as they can damage the material. Instead, opt for a gentle detergent specifically designed for delicate fabrics. These milder detergents are usually free from harsh chemicals and are formulated to preserve the elasticity and colors of your swimsuit.
Using the right amount of detergent is also important. Too much can leave a residue on the fabric, while too little may not effectively remove dirt and body oils. Follow the detergent manufacturer’s instructions for the correct dosage.

The Effect of Laundry Detergent on Swimsuits
So, what happens when you use laundry detergent on swimsuits?
1. Loss of elasticity: Laundry detergents contain enzymes and other harsh chemicals that can break down the elastic fibers in your swimsuit. This can lead to the swimsuit losing its shape and not fitting as snugly as it once did. The elasticity in your swimsuit is what keeps it from becoming baggy, so it’s a crucial element to maintain.
2. Color fading: Laundry detergents can also cause the vibrant colors of your swimsuit to fade. Over time, repeated exposure to these strong detergents can make your once brightly colored swimwear look dull and worn out.
3. Fabric damage: The abrasive nature of laundry detergents can harm the fabric of your swimsuit, leading to a rough texture or even holes over time.
4. Shortened lifespan: All of these factors combined mean that using laundry detergent on swimsuits can significantly shorten their lifespan. So, to keep your favorite beachwear around for many summers, it’s crucial to avoid harsh detergents.
How to Use Laundry Detergent on Swimsuits

The following is the best way to wash swimsuits especially when you are using detergents.
- Use a gentle detergent
- Reduce the amount of detergent
- Hand wash your swimsuit
- Avoid scrubbing or wringing
- Air dry
1. Use a gentle detergent
Not all laundry detergents are created equal. If you must use one, opt for a gentle or mild laundry detergent. These usually have fewer harsh chemicals and are better suited for delicate fabrics.
2. Reduce the amount of detergent
You don’t need a lot of detergents to clean a swimsuit. Use only half of what you’d typically use for a small load of laundry. Remember, less is more in this situation.
3. Hand wash your swimsuit
Rather than throwing your swimsuit in the washing machine, consider hand washing it. Fill a sink or basin with cool water, add the detergent, then gently agitate the water to mix. Add your swimsuit and let it soak for about 15 minutes, then rinse thoroughly with cool water.
4. Avoid scrubbing or wringing
Never scrub or wring out your swimsuit, even if it’s heavily soiled. These actions can damage the fabric and cause the swimsuit to lose its shape. Instead, lightly squeeze the water out.
5. Air dry
After washing, gently roll your swimsuit in a clean, dry towel to remove excess water, then lay it flat to air dry. Avoid direct sunlight, which can fade the colors, and never use a dryer, as the heat can damage the fabric’s elasticity.
Swimsuit Cleaning Alternatives
There are several safe and effective alternatives for cleaning your beachwear.
1. Swimsuit Cleaner
Swimsuit cleaners are specially formulated to clean, deodorize, and extend the life of your swimsuits. They’re designed to be gentle on delicate fabrics and safe for the colors.
Similar to using a mild detergent, you’ll want to fill a basin with cool water, add the recommended amount of swimsuit cleaner, soak your swimsuit for about 15 minutes, then rinse well.
They’re made specifically for swimsuits, making them a safe and effective cleaning option. They can help extend the life of your swimsuit.
They might be a bit more expensive than regular detergent, and you’ll have to buy a separate product just for your swimsuits.
2. Mild Soap
A gentle, fragrance-free soap is a great alternative to laundry detergent. Baby soap or gentle dish soap can be used.
Fill a sink with cool water, add a small amount of the soap, mix the water to create suds, then add your swimsuit. Soak it for about 15 minutes, then rinse thoroughly.
Gentle soaps are easy to find and relatively inexpensive. They’re much less likely to damage your swimsuit than laundry detergent.
They might not clean quite as effectively as a swimsuit cleaner, especially on very soiled swimsuits.
3. Vinegar
Vinegar is a natural, safe alternative that can help remove body oils and neutralize chlorine.
Fill a sink with cold water, add a cup of white vinegar, then soak your swimsuit for 30 minutes. Rinse well with cool water.
Vinegar is inexpensive and readily available. It can also help to naturally deodorize your swimsuit.
The smell of vinegar might be off-putting to some, and it needs to be rinsed very well to remove the scent from your swimsuit.
Can You Use Fabric Softener on Swimsuits?
No, it is not advisable to use fabric softener on swimsuits. While fabric softeners are useful for many types of clothing to make them feel softer and reduce static, they’re not suitable for all fabrics.
Swimsuits are typically made of synthetic, elastic materials such as Lycra, spandex, or nylon, designed to stretch and conform to the body. Fabric softeners work by coating the fibers of the fabric to make them feel softer and smoother. However, when used on swimsuits, this coating can damage the elasticity of the material, causing it to lose its shape over time.
Top Tips for Caring for Your Swimsuits
Taking care of your swimsuit doesn’t stop at washing. Here are some top tips for caring for swimsuits and prolonging their lifespan:
1. Rinse after each use
After every swim, rinse your swimsuit thoroughly in cold water. This helps to remove the bulk of the salt, chlorine, and body oils that can damage the fabric. You don’t need any soap or detergent for this; just let the water do its work.
2. Don’t sit directly on rough surfaces
Avoid sitting directly on rough surfaces, like pool edges or wooden benches, which can cause snags or pilling. Use a towel as a barrier between your swimsuit and the surface.
3. Avoid hot tubs
Hot tubs are not friends to your swimsuits. The combination of high temperatures and chemicals can cause the colors to fade and the fabric to lose its elasticity. If you can’t resist the hot tub, consider having a designated swimsuit just for this purpose.
4. Rotate your swimsuits
If you’re a regular swimmer, consider having more than one swimsuit and rotating them. This will give each swimsuit a break and allow it to return to its original shape, which is a key part of caring for swimsuits.
5. Store properly
Store your swimsuit flat and unfolded it. Hanging can cause the swimsuit to stretch while folding can create creases.
6. Don’t iron or bleach
Never iron your swimsuit as the heat can be damaging. Also, avoid using bleach as it is too harsh and can destroy the fabric and color.
7. Follow the manufacturer’s instructions
Finally, always follow the care instructions on your swimsuit’s label. These instructions are given by the people who know your swimsuit best.
