Bathing suits turn green due to the presence of algae in the pool water. Algae are microscopic plants that can grow in your pool, especially when there’s an inadequate level of chlorine. When you wear your bathing suit in a pool with algae, the microscopic algae can transfer from the water onto your swimsuit, causing green stains on bathing suits.

Other factors that can cause bathing suits to turn green include chlorine, sunlight, detergent, sunscreen, and copper. If not properly taken care of, these five items can lead to color variations in our swimwear.

Let’s explore the causes of swimsuits turning green and share some tips on how to protect your bathing suits from algae and other factors that cause discoloration. I will also provide practical advice on how to remove green stains from your swimsuits, so you can enjoy them for many summers to come.

Why Do Swimsuits Turn Green? – The Major Causes

If you’ve ever wondered, “why has my swimming costume gone green?”, there are a few common culprits. The primary cause of green stains on bathing suits is algae growth, which can occur due to several factors, including:

Chlorine reaction

While chlorine is an essential component of pool maintenance, it can also contribute to the formation of algae on swimsuits. Chlorine reacts with the body’s natural oils and sweat to create chloramines, which can cause green discoloration on bathing suits.

Over time, the constant use of a bathing suit in chlorinated water can cause the bathing suit to change to a completely different color, usually green. However, using a chlorine-resistant bathing suit can help to prevent this color change.

Exposure to sunlight

Exposure to sunlight can weaken swimsuit materials, making them more susceptible to discoloration and algae growth. Although quality bathing suits are made with carefully selected and long-lasting materials that can withstand sun exposure, low-grade bathing suits are prone to color change when exposed to sunlight.

Copper reaction with chlorine

The amount of copper in pool water can react with the chlorine in the water to create an irritating substance known as copper sulfate. This crystal-like material can appear on your bathing suit like a greenish crust and cause green stains on bathing suits.

Use of harsh detergent

Using harsh detergents can damage the fibers in bathing suits and contribute to the formation of algae stains.

Sunscreen damage

Certain sunscreens can cause green stains on bathing suits, so it’s important to choose a sunscreen that won’t damage your swimwear.

How to Protect Bathing Suits From Turning Green

Fortunately, there are several steps you can take to protect your bathing suits from turning green:

  1. Rinse your swimsuit in cool water after each use to remove any residual chlorine, sunscreen, or other chemicals.
  2. Avoid leaving your swimsuit in direct sunlight for extended periods, and store it in a cool, dry place.
  3. Wash your swimsuit with a mild detergent designed specifically for swimwear, and avoid using fabric softeners or bleach.
  4. Consider wearing a chlorine-resistant swimsuit, which is designed to withstand exposure to chlorine and other chemicals.

How to Get Green Out of Swimsuits

There are several ways by which you can get out green stains left by chlorine on your bathing suit. But, I will give out the two most effective ways by which this can be accomplished. Here are two methods that can be used to get green out of bathing suit. 

Method 1: Lukewarm Water and Oxygen Bleach

1. Wash the bathing suit by hand

If you have the energy to wash it, you may be able to remove any lingering stains with a mild detergent and some agitation. This should be done immediately after your swimming activities. It is advised to wash your bathing suit by hand rather than by washing machine.

2. Wash the bathing suit with cold water

Wash the bathing suit by hand in cold water using a mild soap such as baby shampoo and cold water. If you are planning on machine washing your bathing suit, make sure that you turn your bathing suit inside out first, use cold water only during its final rinse cycle to remove any residual chlorine that may remain in the bathing suit.

3. Fill a bathtub with lukewarm water

Baby bathtubs are perfect for this as they take up less space and are easy to fill + drain without turning on your sink or showerhead. Then add oxygen bleach into it so that we can soak our outfits overnight without ruining them completely. This should be done after washing with cold water and detergent. The excess washing with cold water and detergent is to get rid of dirt.

4. Soak for 30 minutes

Soak the bathing suit for about 30 minutes in the solution and then rinse with cool water. Do this twice before attempting to wash it. This will help “set” the color so that it does not bleed or fade as much during subsequent washings and neutralizes any remaining chlorine in the fabric.

It’s important not just because it will remove any leftover stains but also preserve their brightness after many wears. It is a win-win situation all around. The fabric softener should keep them soft too. 

Method 2: Using Vinegar and Baking Soda

Getting the green out of bathing suits can be easier than you think. If you get out of the pool in a bathing suit that has turned green, there’s no need to panic. With a little bit of effort and some basic supplies, your suit will be back to its original color in no time.

Just follow these steps:

1. Get a warm water

Mix one quart (32 ounces) of warm water with 1/4 cup white vinegar and 1/4 cup baking soda. Add the measured vinegar and baking soda after boiling the water to a suitable degree. You can mix it up with a wooden stick.

2. Soak your bathing suit for about 30 minutes

Soak your bathing suit inside the mixed warm water. Allow it to soak for about thirty minutes. Failure to do that may not permit the green to remove effectively.

3. Rinse your bathing suit until the water runs clear

After thirty minutes, you can now remove your bathing suit from the warm water. Ensure you rinse with cold water. Using warm water to rinse can make your bathing suit stretch. 

4. Launder as usual or allow it to air dry on a towel

Gently squeeze out the water using a towel and dry your suit in a conducive environment. Avoid direct contact with sunlight. 

Method 3: Chlorine Bleach Solution

Add a small amount of chlorine bleach to a large bowl of cold water. Soak your swimsuit in the solution for 10-15 minutes, then rinse it with cold water.

Why Is My White Swimsuit Green?

If your white bathing suit has turned green, it’s most likely due to exposure to chlorine or algae in your swimming pool.

Copper reacts with chlorine to form copper sulfate, which can cause green discoloration on white swimsuits. Algae can also transfer onto your white swimsuit, causing green stains.

To remove green stains from your white swimsuit, try soaking it in a mixture of warm water and white vinegar for 30 minutes before rinsing with cool water.
