Summer is here and it’s time to hit the beach or pool. But, have you ever noticed yellow or orange stains on your swimsuit after applying sunscreen? 

These stains can be frustrating and hard to remove but don’t worry, there are ways to prevent and remove them. 

In this article, we’ll explain what causes sunscreen stains, how to remove them, and tips to prevent them from happening again.

What Causes Sunscreen Stains on Swimsuits? 

Sunscreen is made up of various ingredients including chemicals and minerals that can react with the fabric of your swimsuit. 

The most common culprits of sunscreen stains are oxybenzone and avobenzone. These ingredients can cause yellow or orange stains that can be hard to remove. 

Additionally, the type of fabric your swimsuit is made of can also contribute to the stains. Fabrics like nylon, spandex, and polyester are more likely to hold onto sunscreen stains.

How to Remove Sunscreen Stains from Swimsuits

  1. Rinse your swimsuit with cold water to remove any excess sunscreen.
  2. Apply a pre-treatment solution to the stain. Mix baking soda and water to create a paste and apply it to the stain. Let it sit for at least 30 minutes before washing.
  3. When washing your swimsuit, use a gentle detergent and wash it by hand. Avoid using hot water as it can set the stain.
  4. Gently rub the fabric together to remove the stain. If the stain persists, repeat the pre-treatment and washing process until the stain is gone.
  5. Alternatively, you can use vinegar or lemon juice as a pre-treatment solution. Apply the solution to the stain and let it sit for 10-15 minutes before washing.
  6. If the stain is still visible, consider using a stain remover that is specifically designed for removing sunscreen stains.

By following these steps, you can effectively remove sunscreen stains from your swimsuit and keep it looking great all summer long. 

Remember to act quickly when you notice a stain and to avoid using hot water or harsh detergents, which can set the stain and make it more difficult to remove.

Tips to Prevent Sunscreen Stains on Swimsuits 

The best way to prevent sunscreen stains is to apply sunscreen before putting on your swimsuit. This will allow the sunscreen to fully absorb into your skin before coming into contact with your swimsuit. 

Also, choose a sunscreen that is less likely to stain your swimsuit. Look for sunscreens that are labeled “stain-free” or “non-staining.”
