How To Remove Sunscreen Stains – Your 1-0 Win Over The Stain

How to remove sunscreen stains

I suppose all of us know the importance of sunscreens while in the sun. But together with all of the benefits they can cause you some headache, as well.

It is due to the fact that you can find yourself with your brand new bathing suit (or cover-up) showing off some either greasy oily-looking or dark-brown rusty stains. So the fact is that sunscreens are capable of creating these stains unless you deal with it at once.

While the greasy ones are the most common ones, the rust ones are the most difficult ones.

Learn these simple steps to get rid of sunscreen stains. The good news is that actually, it is not hard at all to remove these stains as long as few tips are kept in mind.

Why Do The Stains Appear?

The sunscreen stains appear on the fabric due to the chemical ingredients the sunscreen contains.

There is a substance in the majority of sunscreens reacting with minerals found in water and this reaction is what causes the dark-brown or sometimes yellowish stains.

Consequently, if there is a high mineral composition in your water, it is a good idea to avoid using sunscreens containing avobenzone as this is the substance reacting with the minerals in the water.

The harder the water, the more persistent the stain.

The more synthetic the material, the more persistent the stain.

Owing to the fact that swimsuits are made of synthetic materials, this is particularly relevant bathing suit problem, especially if you live in the area where the water is hard.

I live in the area with very hard water. Consequently, this is a big problem for us and this instruction is like a godsend to me.

So How To Remove These Stains?

The sunscreen stain should be treated right away to avoid them taking form. So whether you pre-treat the stain or wash the garment at once, the main thing is to do something immediately. Otherwise, the things will become really difficult.

In many cases, the immediate wash will not be possible. Therefore, the first aid is an important step to make things easier later.

Step#1 – First Aid

The first thing to do is to remove any solids. Afterwards, put some sand, cornstarch, bi-carb soda or talcum powder on the stain for 15 minutes or more (for the best results, let it be half an hour, if possible). Sand, cornstarch, and powder are perfect means for absorbing the oil till you will be able to wash the swimsuit as needed.

When at least fifteen minutes have passed, lightly brush them away. The main emphasis here is on the word – lightly. Remember to avoid rubbing your swimsuit as it can lead to a breakdown of the fine fabric.

Step#2 – Treating

When you get at home – the time has come to take proper care of the swimsuit (or cover up or any other garment that has the stain).

If your water is soft, just put some prewash stain remover on the stain and lightly massage it into the material. The best choice of prewash stain remover fro swimsuit would be the one designed for delicate fabrics for cutting through the oil/grease.

If your water is hard, it is a good idea to make it softer by using a water softener or distilled water. Afterwards, follow the instructions mentioned above. And this should be obeyed during both treating and washing stage.

Let the stain remover settle for 15 – 30 minutes.

Step#3 – Washing

When the prewash stain remover has worked for 15 – 30 minutes, wash your swimwear as usual by following these swimsuit washing instructions.

If the stain has appeared on your cover-up or another piece of clothing, just follow the washing instructions on the relevant garment.

If you have hard water, don’t use too hot water or chlorine bleach as it will only lead to a more severe problem.

If the sunscreen mark was on the white clothes and the above steps didn’t help you, don’t worry. There are few more additional steps to take to deal with this.

  1. When the white clothes are washed, hang them in the sun by sprinkling the lemon juice on the stain and area around it. Owing to the bleaching properties of the lemon juice, it is a good solution to deal with difficult stains.
  2. Another solution is to use some chemical bleacher by following the instructions, though I do prefer the more natural one.

The Safest Way to Remove the Stain is to Avoid It 🙂

If you don’t feel comfortable with the stain removal procedure, especially for the sensitive swimwear fabrics, the best would be to avoid the stains. And it is not hard at all.

To begin with, apply your sunscreen before dressing up and let it dry. There is actually more to this than just avoiding the sunscreen stains. The truth is that sunscreens perform greater and protect your skin better if properly soaked and absorbed into the skin. These would be about 15 minutes or so.

Another important rule is to avoid using your sunscreen too much or too excessive amounts of it – just by limiting the amount you can avoid the possibility of getting the stain.

Another way to avoid getting the stains is to purchase the sunscreen without avobenzone though this leads to limited choice.

Know the Material Before Using It

There are certain materials more likely to get sunscreen stains. There is no such thing as immunity to getting the stains, but it is good to know that some materials are more susceptible than others.

Susceptibility to stains of synthetic fibers is well known. I bet you have noticed the sweat stains on the synthetic fibers as this is the most common visual stain problem.

So knowing the material and choosing the right one when there is a possibility to stain can be of great help to you.


Cotton is a well-known natural material, often used for cover-ups and light summer-dresses. It is not only versatile and pleasant but also tough and durable fabric.

The good news is that it is easy to remove stains out of it just by using relevant detergent or light acid. Quite a popular way to get rid of stains on cotton is to use either lemon juice or vinegar. Cotton easily holds up to being soaked and dried without any limitations.


Synthetics are among the materials which are more likely to get stains. Even though they tend to be extremely durable and sturdy, bleaching or other oxidizing agents will deteriorate the fabric very quickly.

In order to remove stains from synthetics, you should use laundry detergent or dish soap in case of oily stains.


Silk is sometimes used for cover-ups and summer dresses due to its outstanding properties making it particularly suitable for this purpose. I have described it more in details here.

Silk is considered as the tricky material when it comes to the cleaning. And it is a reason many of us avoid silk clothing. However, it just requires some more knowledge on the stain removal and caring for this excellent material. And believe – this is so much worth it. It is even impossible to describe the feelings in words when you are wearing silk.

Whenever there happens to be a stain on the silk, you should take a damp cloth and lightly wipe away the stain. After that, rinse the material immediately by using special silk shampoo or baby soap. The main idea here is not to let the stain to dry.
