Washing your BJJ gi properly requires washing in cold water immediately after every training session to prevent bacteria buildup and odor, using gentle cycle with mild detergent (no fabric softener or bleach), air drying by hanging in well-ventilated area to prevent 10-15% shrinkage from machine drying, and washing your belt along with the gi since it accumulates the same bacteria and sweat. Hayabusa Fight explains: “The best way to clean a jiu-jitsu gi is to use cold water, which is as effective at getting your uniform clean but not as harsh—hot water will likely shrink your gi and damage fibers”. Easton BJJ warns: “Remove your gi from the wash immediately after the cycle ends so it doesn’t develop a terrible smell from sitting soaking wet in your washer, and never machine dry your gi unless you intentionally want to shrink it”.

Proper gi care extends the lifespan of your first BJJ gi investment from 6 months to 3+ years, prevents embarrassing odor that disrespects training partners at BJJ classes, maintains proper gi sizing through shrinkage prevention, and stops bacteria growth that causes staph infections and ringworm. This guide covers step-by-step washing instructions, preventing shrinkage, removing stubborn odors, proper drying techniques, storage tips, and common mistakes to avoid.

How to Wash Your BJJ Gi: The Complete & Human Guide

Step-by-Step Washing Instructions

Pre-Wash Preparation

Immediately after training:

Remove gi from gym bag as soon as you get home
Elite Sports emphasizes: “Never leave your dirt and sweat-drenched gi sit overnight in your BJJ bag—even if you are tired, wash your gi after the training session to prolong its lifespan”
Shake out any debris or loose items
Turn gi inside out (reduces pilling, protects patches)
Check pockets for mouthguards or other essential BJJ gear

Pre-soak for odor prevention (optional but recommended):

Fill basin with cold water
Add 1 cup white vinegar or 1/2 cup baking soda
Soak gi for 15-30 minutes
Fight Aesthetic explains: “Adding a small amount of white vinegar to the wash can help preserve the fabric’s integrity and prevent any lingering odors”

Machine Washing Settings

Easton BJJ washing guidelines:

Water temperature: COLD ONLY

Cold water (30°C/86°F or lower)
Never use warm or hot water
Hot water causes 10-15% shrinkage
Damages fabric fibers permanently
Ruins proper gi fit

Cycle setting: GENTLE

Delicate or gentle cycle reduces wear
Gis get washed 100+ times per year
Harsh cycles shorten gi lifespan
Protects stitching and seams

Detergent: MILD, NO ADDITIVES

Use quality mild detergent (Tide Free, All Free & Clear)
Amount: 1/2 to 3/4 normal amount (gis don’t need much)
NEVER use fabric softener (coats fibers, traps bacteria, reduces absorbency)
NEVER use bleach (weakens fabric, damages color, shortens lifespan)

During the Wash Cycle

Load size:

Wash gi separately or with other gis only
Don’t mix with regular clothes (gi abrasiveness damages other items)
Don’t overload machine (gi needs room to agitate properly)
One gi per small load, 2-3 gis in large capacity machine

Add white vinegar (recommended):

Pour 1/2-1 cup white vinegar in fabric softener dispenser
Natural deodorizer and bacteria killer
Helps maintain fabric integrity
Prevents color fading

Post-Wash Actions

Easton BJJ critical reminder: “Remove your gi from the wash immediately—this is so your gi doesn’t develop a terrible smell from sitting soaking wet in your washer for hours on end”.

Immediate removal:

Set timer for wash cycle completion
Remove within 5-10 minutes of cycle ending
Sitting wet in machine = mildew smell
Shake out gi to release wrinkles

Preventing Shrinkage: Critical Guidelines

The Golden Rule: Never Machine Dry

BJJ Fightgear explains shrinkage prevention: “Opt for air drying your gi by hanging it in a well-ventilated area—this not only prevents shrinkage but also prolongs the lifespan of your gi by reducing wear and tear”.

Machine drying consequences:

10-15% shrinkage in single dryer cycle
Sleeves/pants become competition-illegal length
Ruins expensive gi ($80-$120 wasted)
Damages fabric fibers permanently
Only use dryer if intentionally shrinking oversized gi

Proper Air Drying Method

Best drying locations:

Outdoor clothesline (sunlight kills bacteria naturally)
Indoor drying rack in well-ventilated room
Bathroom with fan running
Garage or covered porch area

Hanging technique:

Hang gi jacket on wide hanger (prevents shoulder stretching)
Hang pants by waistband with clips or over bar
Ensure good air circulation around all parts
Don’t bunch up fabric (promotes even drying)

Drying time:

Summer/warm climate: 4-8 hours outdoors
Winter/cold climate: 12-24 hours indoors
Heavyweight gis: 24-48 hours
Elite Sports advises: “The UV rays are a natural odor killer—it will instantly kill the smell-causing bacteria”

Steam to Remove Wrinkles

BJJ Fightgear recommends steaming: “After washing and air drying, use a steamer to release any wrinkles—this gentle approach helps relax the fabric without subjecting it to excessive heat, contributing to the prevention of shrinkage”.

Steaming benefits:

Removes wrinkles without heat damage
Relaxes fabric gently
Maintains proper size
Professional appearance for competitions

Removing Stubborn Odors

Why Gis Develop Smell

Elite Sports explains odor causes: “Your BJJ gi can turn smelly due to the buildup of bacteria and sweat from training—when you train, you sweat, and the sweat gets absorbed into the fabric of the gi, creating a warm, moist environment that’s the perfect breeding ground for bacteria”.

Common causes:

Not washing immediately after training
Sitting wet in gym bag overnight
Insufficient detergent or cold rinse
Machine drying (traps bacteria in fibers)
Not washing belt (transfers smell back to gi)

Deep Cleaning Methods

Baking soda soak:

Fill bucket with cold water
Add 1-2 cups baking soda
Soak gi for 3-5 hours
Wash normally afterward
Elite Sports notes: “Baking soda is an amazing agent for not only removing smell but also whitening your gi which is turning yellow”

White vinegar treatment:

Add 1-2 cups white vinegar to wash cycle
Vinegar neutralizes odors naturally
Kills bacteria effectively
Safe for all gi colors and fabrics

Enzyme cleaner (for persistent odor):

OxiClean, Nature’s Miracle, or Sport Suds
Pre-soak for 1-2 hours
Follow with normal cold wash
Effective on old, neglected gis

Sunlight exposure:

Hang gi in direct sunlight
UV rays kill odor-causing bacteria
Natural bleaching effect (whitens white gis)
Free and environmentally friendly

Should You Wash Your BJJ Belt?

The Controversy

RVCA answers definitively: “Your jiu jitsu belt is exposed to the same bacteria as your gi—to keep your jiu jitsu belt in good condition, wash it every time you wash your gis”.

Reasons to wash belt:

Accumulates same bacteria as gi
Harbors staph and ringworm
Smells just like gi (partners notice)
Hygiene and respect for training partners

Old myth (ignore this):

“Never wash belt, it holds your knowledge”
Myth from pre-modern hygiene era
No legitimate instructor supports this
Modern BJJ culture values cleanliness

How to wash belt:

Include with gi in same wash
Cold water, gentle cycle
Air dry flat or hanging
Slight shrinkage expected but minimal

Storage and Maintenance

Proper Storage Between Training

After drying completely:

Hang gi in closet on wide hanger
Store in dry, well-ventilated area
Never store damp (promotes mildew)
Fold neatly if storing in gym bag for class

Avoid these storage mistakes:

Leaving in gym bag between sessions
Storing in humid bathroom
Plastic bags (traps moisture)
Direct sunlight long-term (fades color)

Rotation Strategy for Multiple Gis

Why own 2-3 gis:

Train 3-4x weekly = need backup while one dries
Extends lifespan (each gi washed less frequently)
Always have clean gi ready
Total investment: $160-$360 for 2-3 gis

Rotation schedule:

Monday/Wednesday: Gi #1
Tuesday/Thursday: Gi #2
Friday/Weekend: Gi #3 (if needed)
Each gi fully dries between uses

Common Gi Washing Mistakes

Mistakes That Ruin Gis

Using hot water:

Single hot wash = 10-15% shrinkage
Damages fabric permanently
Ruins expensive investment

Machine drying:

Fastest way to destroy gi
Shrinks beyond repair
Weakens seams and stitching

Not washing immediately:

Bacteria multiplies exponentially
Odor becomes permanent
Disrespectful to training partners at BJJ classes

Using fabric softener:

Coats fibers with waxy buildup
Traps bacteria inside fabric
Reduces gi absorbency
Makes gi slippery (affects grips)

Ignoring manufacturer instructions:

Each brand has specific care guidelines
Pre-shrunk vs. shrinkable differences
Reference: Choosing Your First BJJ Gi covers brand differences
