How to Keep Your BJJ Rash Guard Fresh: Care Tips to Prevent Odor and Extend Its Life

Quick Answer

The best way to keep your BJJ rash guard fresh is to wash it after every training session, allow it to air dry whenever possible, and avoid leaving it damp inside your gym bag. Consistent care helps prevent odor, protects the fabric, and extends the life of your rash guard.

Why Rash Guards Need Proper Care

A rash guard works hard every time you step onto the mats.

It absorbs sweat.

It stretches through every movement.

It rubs against your gi, your training partners, and the mats throughout every roll.

Even though rash guards are designed for demanding training, they still need proper care if you want them to last.

Fortunately, keeping one fresh is simple.

Wash Your Rash Guard After Every Training Session

This is one habit that should never be skipped.

Even if your training session was short, your rash guard has absorbed sweat and moisture.

Waiting until after your next class only gives odor more time to develop.

Wash it after every session.

Your training partners will appreciate it.

Step 1: Remove It From Your Gym Bag

Don't leave your rash guard sitting in a closed gym bag after training.

The sooner it comes out, the sooner it can dry or be washed.

Step 2: Turn It Inside Out

Turning your rash guard inside out before washing helps expose the areas that collect the most sweat.

It's a simple step that can improve cleaning.

Step 3: Wash in Cold Water

Cold water helps preserve the elasticity, stitching, graphics, and compression fabric found in most rash guards.

Always follow the manufacturer's care instructions if they recommend something different.

Step 4: Use a Mild Detergent

A quality detergent is usually all you need.

Using excessive detergent may leave residue behind that can affect the fabric over time.

Step 5: Air Dry Whenever Possible

High heat may shorten the life of compression fabrics.

Whenever possible, allow your rash guard to air dry naturally.

Don't Forget the Rest of Your Gear

Your rash guard goes into the washing machine.

Many other pieces of equipment don't.

After every training session, take a few moments to care for the rest of your gear too.
