How to Wash and Care for Your BJJ & MMA Rashguards

Follow your rashguard’s care label first. For a simple routine, wash after training, turn it inside out, use cold water and mild detergent on a gentle cycle, then air-dry. Avoid bleach, fabric softener and tumble-dryer heat unless the care label specifically permits them.

How to wash a rashguard: step by step

Read the care label for washing temperature and drying instructions.
Turn the rashguard inside out before washing.
Wash with similar colours. Keep it away from exposed hook-and-loop fasteners and other items that could snag the fabric.
Use cold water, a gentle cycle and mild detergent suitable for the garment. Follow the detergent’s dosing instructions.
Remove it promptly after washing and hang it to air-dry.

How often should you wash a rashguard?

Wash your BJJ or MMA rashguard after each training session. If you cannot wash it straight away, take it out of your gym bag and hang it in a ventilated space until you can. Airing a used rashguard is a temporary step before washing.

Which detergent should you use?

Choose a mild detergent suitable for the garment and follow both the care label and the detergent instructions. Avoid bleach and fabric softener. Do not add household treatments such as vinegar unless the garment manufacturer’s care instructions allow them.

If an odour remains after washing, check the detergent dose and washing instructions before repeating the wash. Let the rashguard dry completely before storing it.

Can you put a rashguard in the dryer?

Air-dry your rashguard in a ventilated space away from direct sunlight and strong heat. Avoid the tumble dryer unless the care label specifically allows it. Check the label before ironing or using any other heat treatment.

How should you store your rashguard?

Store it clean and completely dry. Keep damp training gear out of closed bags, and avoid leaving the rashguard against rough surfaces or exposed hook-and-loop fasteners that can catch the fabric.

Does the same routine apply to short and long sleeves?

Use the care label on the individual garment for both sleeve lengths. Sleeve coverage alone does not determine the washing instructions. If you are choosing a new top, our rashguard fit and sizing guide compares short and long sleeves and explains how to use the size charts.
