Learn how to wash, dry, and store your rash guard so it stays stretchy, sun-protective, and odor-free through many seasons.

Quick Answer

Rinse your rash guard in cold water after every use, wash it on a gentle cycle with mild detergent, and air dry it away from direct sunlight.

Why Regular Care Matters

A rash guard is made of stretchy synthetic fabric that can break down from chlorine, salt, sweat, and UV rays if not cleaned promptly. Sunscreen oils also cling to the fibers and can cause discoloration over time.

The ʻElekū Men's Rash Guard features a 82% polyester, 18% spandex blend with a UPF 38-40 rating. Proper care preserves both the fit and the sun protection.

Frequently Asked Questions About Rash Guard Care

How do I wash my rash guard?
Turn it inside out, use cold water on a gentle cycle, and add a small amount of mild detergent. Avoid fabric softeners and bleach.
Can I machine dry my rash guard?
No. High heat damages spandex. Lay it flat on a towel or hang it in the shade to air dry. Never wring it out.
How do I remove odors from my rash guard?
Soak it in a mixture of cold water and white vinegar (1 part vinegar to 4 parts water) for 15 minutes before washing. Rinse thoroughly. For stubborn smells, repeat the soak or use a sports-specific wash.
Should I rinse my rash guard after every use?
Yes. Rinse it with cold fresh water immediately after swimming in salt water, chlorinated pools, or hot tubs to remove chemicals and salt crystals.
How do I store my rash guard?
Store it flat or folded in a cool, dry drawer. Do not hang it by the shoulders for long periods; the weight can stretch the neckline.
