How to Wash a Rashguard (With Steps)

Rashguards like any other apparel used in Jiu Jitsu or Mixed Martial Arts will need to be washed after each use not just for your own safety and hygiene but for the safety and hygiene of your training partners as well. Here’s everything you need to know about how to wash a rashguard and keep it clean.

What You’ll Need

  • Washing Machine or Sink/Bucket - Due to their durable nature, Rashguards are totally safe to wash in a conventional washing machine in a delicate setting, but can also be washed by hand.
  • Antibacterial Laundry Detergent - Though a normal detergent will often be sufficient, it’s recommended to use one with antibacterial properties as the absorbent fabric of the Rashguard is perfect environment for bacterial growth.
  • Drying Rack - If possible it’s recommended to air dry your Rashguards as a drier could potentially damage or weaken the fabric over time.

Instructions on How to Wash a Rashguard

  • If you’re going with the washing machine, then simply load as normal and add your antibacterial detergent and run it on a cold water and delicate cycle.
  • For hand washing, fill your sink or bucket with cold water and antibacterial detergent and let soak for at least five minutes and then scrub by hand.
  • For either method gently ring out the Rashguard and let hang until dry.

Stain Removal

It’s not uncommon for your Rashguard to pick up some stains while training and luckily there is an easy method for getting them back to their former glory.

  • Fill a sink or bucket with cold water, and add white vinegar or an oxygen bleach such as Oxiclean and let soak for 8 hours. Rinse well after and hang to dry. Repeat the process as needed.

Tips for Care

Rashguards are durable and tough but if you’re looking to maximize their longevity here are some tips to keep them in good shape for as long as possible.

  • To reduce the chance of stains setting, don’t let your sweat drenched rash guard cook in a hot car after training.
  • Try to wash or at least rinse the Rashguard as soon after training as possible to limit the amount of bacterial and mildew growth.
  • Don’t wad up your rashguard and stuff it in your gym bag as this can weaken the fabric over time
  • Wash your Rashguard inside out, this will help keep the dyes from fading as quickly.
