Wash your BJJ rash guard by turning it inside out, using cold water, and choosing a gentle detergent. Avoid bleach and fabric softeners. Air dry to preserve elasticity and prevent damage. Wash after every training session to reduce odor and bacteria buildup.
Why Proper Washing Matters
In this guide, we’ll walk you through the best practices for cleaning your BJJ rash guard so it stays in top condition for every training session.
Rash guards are typically made from a blend of synthetic fibers like polyester and spandex. These materials are designed for performance—offering stretch, durability, and breathability. But improper washing can damage these features, causing the fabric to degrade, shrink, or lose its elasticity. Worse, lingering sweat and bacteria can lead to foul odors and even skin infections.
That’s why it’s essential to develop a consistent cleaning routine that maintains your rash guard’s structure, smell, and hygiene.
Step-by-Step Guide: How to Wash Rash Guard Correctly
1. Rinse Immediately After Training
Right after your session, give your rash guard a quick rinse in cold water. This helps remove sweat, body oils, and any bacteria or debris from the mats. Even if you can’t wash it right away, rinsing prevents buildup that can damage the fabric over time or lead to unpleasant odors.
2. Hand Wash When Possible
While many athletes toss their gear straight into the washing machine, hand washing is the gentlest method for maintaining your rash guard. Use lukewarm water (never hot!) and a mild detergent. Gently rub the fabric to clean it, focusing on heavily used areas like the armpits and chest. Avoid scrubbing harshly—your goal is to clean, not wear it down.
3. Use Cold Water and a Gentle Cycle in the Machine
If hand washing isn’t practical, you can machine wash your rash guard—just be sure to take precautions:
- Turn it inside out to protect printed designs and logos.
- Use cold water and set the washer to a gentle or delicate cycle.
- Place your rash guard in a mesh laundry bag to prevent friction with other items.
Never use hot water. Heat breaks down the stretchy fibers in your gear, causing it to lose its snug fit and lifespan.
What to Avoid
Some common laundry habits can actually do more harm than good. When cleaning your BJJ rash guard, avoid the following:
❌ Fabric Softeners
Softeners leave a residue on synthetic fabrics, reducing their breathability and moisture-wicking properties. They also degrade the elasticity of your gear.
❌ Bleach
While bleach kills bacteria, it’s far too harsh for your rash guard. It can damage the fibers, fade colors, and weaken the overall fabric.
❌ Tumble Drying
High heat is the enemy of spandex and polyester. Instead of tossing your rash guard in the dryer, air dry it flat or hang it in a shaded, well-ventilated area. Avoid direct sunlight to preserve colors and prevent fading.
How to Eliminate Stubborn Odors
If your rash guard starts to hold on to unpleasant smells despite regular washing, it may be time for a deeper clean. Here are a few odor-fighting tips:
- Vinegar Soak: Mix one part white vinegar with four parts cold water and let your rash guard soak for 30–60 minutes before washing. Vinegar naturally breaks down odor-causing bacteria.
- Enzyme-Based Detergents: Use products designed to target protein-based stains and smells (like sweat). These detergents break down bacteria more effectively than standard soap.
- Avoid Overloading the Washer: Give your rash guard space to move around. Cramming too much in one load reduces the efficiency of the wash.
How Often Should You Wash a Rash Guard?
Always. Every. Single. Time.
Even if your training session was light, your rash guard has absorbed sweat and picked up bacteria from the mats and your training partners. Skipping a wash allows those bacteria to multiply, causing both odor and potential skin irritation.
Quick Maintenance Tips
- Keep an extra rash guard in your gym bag if you train multiple times a day.
- Never leave it in your gym bag overnight. Always remove and wash it as soon as you can.
- Avoid ironing your rash guard—heat can ruin the fabric.
- Label your gear if you train at a busy gym, especially during open mats or tournaments.
Final Thoughts
Knowing how to wash rash guard properly is a small but crucial part of your BJJ journey. Clean gear reflects discipline, respect for your training partners, and care for your own health and performance. With the right washing habits, you’ll extend the life of your rash guard and stay fresher, longer, on and off the mats.
So rinse it, wash it right, and roll on.
