How to Care for a Rash Guard

A rash guard is a great investment if you're going to spend time in the water. The harsh sun, sand, and rough waves can be abrasive on your delicate skin. With a rash guard, you'll gain protection from all of those elements. It's important to properly care for your rash guard so you can wear it for seasons to come. In this guide, you'll learn how to properly care for your rash guard.

Always Rinse!

You must hand-rinse your rash guard with cool water right after taking it off. This is a highly important step. Your rash guard is constantly getting bombarded with chlorine, saltwater, harsh sun rays, or natural ocean particles every time you wear it. Rinsing your rash guard with cool water will help remove any fresh residue.


After rinsing, it's time to lather up your rash guard. It's best to use a shampoo or cleaner designed for cleaning rash guards or wetsuits. Biodegradable shampoos are ideal and won't harm the rash guard fabric. Massage your shampoo of choice into your rash guard, making sure to turn the rash guard inside out as well for a thorough clean. Once you are done, rinse your rash guard with clean water to remove any remaining shampoo.

If by chance you don't rinse and shampoo your rash guard immediately, you may start to notice an odor forming. This is due to bacteria. However, there's no need to worry. There are plenty of shampoos available that are focused on removing odor from wetsuits and rash guards. You can also use a mixture of water and baking soda to remove odors. Whether you're cleaning your rash guard in the sink or in a bucket, simply add a cup of baking soda to the water and soak your rash guard in the mixture for 10-15 minutes.

Hang It Up

Once you're done rinsing and shampooing your rash guard, the final step is to hang your rash guard to dry. Wood or plastic hangers are great. The thick, durable nature of a wood or plastic hanger allows your rash guard to hang freely without any pesky shoulder indentations. For this reason, it is advised not to use a wire hanger.

If you are unable to hang your rash guard, you can also lay it flat in a drawer. Laying your rash guard flat is the key to maintaining the shape and longevity. Although it's tempting to toss your rash guard in your car after a long day at the beach, you could permanently damage it. It's best to avoid placing your rash guard in areas of extreme heat like the trunk of your car or outside for long hours. Laying it flat—not crumpled—in a room-temperature or cool area is best.

Enjoy your Rash Guard

Rash guards are available in countless cool colors and have endless features, depending on which one you choose. Protect yourself and your rash guard by properly caring for it. With some basic maintenance, you can keep your rash guard in excellent condition for future uses.

I use a rash guard in my swimming lessons and I always make sure to hang it up and rinse after swimming. But they keep getting these little white dots all over them and I don’t know how to get rid of it. Is it some kind of mold or something growing? I’ve tried both by hand and in the machine and I’ve tried brushing it off by hand but it just keeps getting worse

Hi Grace!

If your rashguard is not chlorine-resistant, then those must be discoloration dots. We recommend using one that is made with 100% polyester as they are color-fast.

The dots aren’t really part of the rash guard though. They come off like some kind of powder or something

We purchased SPORTI rash guards for the kids a couple months ago. They have since developed worn spots where the fabric has deteriorated around the shoulders and some areas on the back and chest. I am not sure if this is due to the quality of the material - or the chlorine? Upon using it this weekend, my son got a sunburn on his shoulders through the shirt. I am hesitant to by the same brand but will it happen to every rash guard?

Hello Carla,
It could be a mixture of the material and the chlorine exposure. Polyester is going to the best material for chlorine as it holds up better. You may have purchased rash guards made of nylon/lycra. These are good materials but they don't hold up well if used often in chlorine. Its also very important to rinse the rash guards in cool water after every use.

i have purchased several rash guard last year through your company. Any tips on how to remove sand. I have let them dry completely so sand can be removed, but that did not help. Also soaked in cold water with oxyi clean which also did not help.

Hello Karen,
Wash your rash guard in a mixture of lukewarm water and mild detergent. Mix one teaspoon of mild detergent per gallon of water. Wash thoroughly and rinse until all the sand is gone. Repeat step three and dry your bathing suit on a large towel.

I only have one rash guard and I use it on my swimming lesson on a swimming pool during Saturdays, and I not knowing how to clean, after using it I hang it to dry for 3 hours and soak it on cool water and dissolved powdered soap for an hour and hand wash it. But after just today, there's brown stuff on the white parts of my rash guard. I have a clue on how that happened, I soak it over night instead of 3 hours. So PLEASE TELL ME HOW TO WASH IT AND GET RID OF THE BROWN STUFF! PLEASE

Hi Nathalie,
You should always rinse your rashguard as soon as you take it off to get rid of any fresh residue. After you rinse it, use a light shampoo to clean it and rinse it again. If possible, hang dry or lay on a flat surface to dry. I hope this helps. Let us know if you have any questions. Have a great day!

Hi Susan,

I'm sorry to hear that you have brown dots on your rashguard. I would advise that you wash it going by the care instructions listed on the inner tag of your rashguard. It should come off. Please let us know if you have any questions or concerns. Have a wonderful day!

Any thoughts on what to do if you swam in the ocean, totally ignorant as to how to care for your shirt and now have tiny little brown dots (critters?) all over your shirt a month latter?
