When you first start Brazilian Jiu-Jitsu, washing your gi might seem straightforward. Yet, anyone who’s shrunk a gi, ruined a competition patch, or developed that infamous “gym funk” knows there’s more to this chore than just tossing it in the wash. In the long run, knowing how to properly care for your gi not only extends its lifespan but also keeps you and your training partners healthy.
Whether you’re brand new to the mats or a grizzled competitor, this comprehensive, transition-rich (and SEO-optimized) guide will walk you through the best practices for washing your BJJ gi — step by step.
Why Washing Your Gi Matters
First and foremost, your gi is a reflection of your respect for your gym, your teammates, and yourself. Not only do clean gis promote better hygiene, but they also reduce the risk of skin infections such as staph or ringworm. Furthermore, consistent cleaning maintains the fabric’s integrity, color, and fit. If you want to get the most out of your investment, proper care is essential.

Step-by-Step Guide: Washing Your BJJ Gi
Let’s walk through each phase of gi care, focusing on creating habits that pay off over time.
1. Immediate Post-Training Actions
As soon as class is over, change out of your gi and let it air out. Never, under any circumstance, leave your sweaty gi balled up in a gym bag overnight. Otherwise, you may return to a gi that reeks — or worse, fosters mildew and bacteria.
- Bring a mesh laundry bag for transport.
- If stained, use cold water for a quick rinse on the spot.
2. Pre-Wash Preparation
Before you toss your gi in the machine, there are a few simple steps you should follow:
- Check the label: Each gi brand varies, but most recommend cold water washing.
- Treat stains early: For stubborn spots like blood, sweat, or grass, soak in cold water with a splash of white vinegar. Scrub lightly with the fabric itself instead of a harsh brush.
- Tie cords and turn inside out: This protects embroidered patches and helps preserve color vibrancy and the fabric’s integrity.
3. Machine Washing Dos and Don’ts
Here’s where attention to detail really matters. Nevertheless, these steps are quite manageable:
Use Cold Water
Always wash your gi in cold (or at most, lukewarm) water — usually no higher than 30°C (86°F). Hot water shrinks and weakens cotton fibers, compromising both fit and durability.
Mild Detergent is Key
Opt for gentle, fragrance-free detergents. Strong chemicals, bleach, and softeners are unnecessary and can degrade fabric, cause discoloration, or trigger skin irritation.
- For persistent odors, consider adding a cup of baking soda or a splash of white vinegar during the wash. This not only eliminates “funk” but is gentle on most gis.
Never Use Bleach
Even though white gis seem tough, bleach can break down the material and create thin spots.
Wash Separately
If possible, avoid mixing your gi with colorful gym clothes, towels, or regular laundry to prevent unwanted color transfer.

4. Drying: The Make-or-Break Step
To prevent shrinkage and maintain your gi’s fit, how you dry is just as important as how you wash.
Air Dry is Best
Hang your gi using a wide hanger in a well-ventilated space, preferably out of direct sunlight. Although sunlight kills some germs, overexposure can make fibers brittle and fade colored gis.
Avoid High-Heat Dryers
If you must use a machine dryer, choose the lowest heat setting — or simply tumble with no heat. Regular drying on high heat is the quickest way to shrink your gi or damage stitching.
For darkest colored gis, drying in the shade maintains color. For white gis, brief exposure to gentle sun can actually help brighten them, but always use moderation.
- Quick tip: Speed up drying by using a fan or increasing air circulation near your gi.
5. Extra Tips for Long-Lasting Gi Care
While basic washing keeps your gi clean, a few added steps go a long way:
- Rotate your gis: If you train frequently, having more than one gi gives each one time to fully dry and rest between uses.
- Store properly: Keep clean gis in a dry location. Damp closets or bags are breeding grounds for bacteria and mildew.
- Inspect regularly: After each wash, check for tears or worn seams to address minor repairs early.

Frequently Asked Questions
1. How often should I wash my gi?
You should wash your gi after every training session. This habit not only keeps your uniform fresh, but also prevents the buildup of odor and bacteria.
2. Can I use regular detergent on my gi?
Yes; however, it’s better to choose a mild, fragrance-free detergent without bleach or strong chemicals. Specialized sports detergents or natural additives like vinegar work even better.
3. How do I get rid of stubborn odors?
Soak your gi in a solution of cold water and white vinegar or add a cup of baking soda to your washing machine. Occasionally strip-washing your gi can help defeat persistent smells.
4. Is it really necessary to air dry my gi?
Whenever possible, yes. Air drying preserves the shape and fit of your gi. Tumble drying with low or no heat is an option if you’re in a hurry, but high heat should always be avoided.
5. Will washing my gi shrink it?
While some minimal shrinkage is normal, washing in cold water and air drying will greatly minimize the risk. Hot water and high heat are the main causes of excessive shrinkage.
Final Thoughts
In short, learning how to wash your BJJ gi properly is just as important as mastering your first submission. By treating your gi with care, not only will you extend its usefulness and prevent shrinkage, but you’ll also contribute to a cleaner, healthier, and more respectable academy. Most importantly, adopting these habits is a sign of respect for yourself and your community. So, take action after every session—air out, wash carefully, dry properly, and you’ll always be welcomed back on the mat.
