Your BJJ gi is an investment. Proper care extends its life from months to years. This guide covers everything you need to know about washing, drying, storing, and maintaining your gi to keep it fresh, functional, and competition-ready.
How Often Should You Wash Your Gi?
After every single training session. No exceptions. Sweat, bacteria, and skin cells accumulate immediately. Rolling in a dirty gi is disrespectful to training partners and creates health risks.
If you train twice a day, you need two gis or a same-day washing routine.
Step-by-Step Washing Instructions
Pre-Wash Preparation
- Turn gi inside out – Protects patches and color
- Close all drawstrings – Prevents tangling
- Check for tears – Repair small rips before they grow
- Pre-treat stains – Blood, mat marks, dirt spots
Washing Machine Settings
| Setting | Recommendation | Why |
|---|---|---|
| Water temp | Cold | Hot water damages fibers, causes shrinkage |
| Cycle | Normal/Gentle | Aggressive cycles wear fabric |
| Load size | Light to medium | Gis need room to move |
| Detergent | Regular, unscented | Fragrances cause irritation |
Detergent Do’s and Don’ts
- ✅ Use: Regular liquid detergent, sports detergent, vinegar
- ❌ Avoid: Fabric softener, bleach, strong fragrances
- ✅ Amount: Standard load amount (do not overdo it)
Odor Control Strategies
The dreaded “stinky gi” syndrome affects every practitioner. Here is how to prevent it:
Vinegar Soak Method
- Fill tub/bucket with cold water
- Add 2 cups white vinegar
- Soak gi for 30-60 minutes
- Wash normally
Baking Soda Boost
Add 1/2 cup baking soda to your regular wash cycle. Neutralizes odors without chemicals.
Sports Detergents
Products like Hex Performance, Sport Suds, or Nathan Sports Wash are designed for synthetic/athletic fabrics.
Drying Your Gi Properly
Hang Dry Only
Never use a dryer. Heat damages the fibers, shrinks the gi excessively, and weakens the fabric. Always hang dry.
Proper Hanging Technique
- Jacket: Hang by collar or shoulders (not sleeves)
- Pants: Hang by waistband or fold over line
- Location: Well-ventilated area, out of direct sunlight
- Time: 12-24 hours depending on humidity
Speed Drying Tips
- Use a fan to increase airflow
- Hang near (not directly on) heating vent
- Dehumidifier in room if very humid
- Rotate multiple gis so you always have a dry one
Gi Storage Best Practices
Never Store Damp
Mildew and bacteria grow quickly in dark, moist environments. Always ensure your gi is 100% dry before storing.
Storage Options
- Gi bag: Breathable fabric bags are best
- Closet hanger: Allows air circulation
- Folded in drawer: Only if completely dry
Avoid:
- Gym bag storage (traps moisture)
- Plastic bags (no airflow)
- Direct sunlight (fades color)
- Stuffed in corner (creases, mildew)
Removing Specific Stains
Blood Stains
- Rinse immediately with cold water (hot sets the stain)
- Apply hydrogen peroxide directly
- Let sit 5 minutes
- Wash normally
Mat Burn/Mat Stains
- Pre-treat with stain remover
- Scrub gently with soft brush
- Wash in warm water (not hot)
Sweat/Yellowing
Mix baking soda and water into paste. Apply to yellowed areas, let sit 30 minutes, then wash.
Maintaining Gi Integrity
Inspect Regularly
Check for these issues weekly:
- Tears in fabric
- Loose stitching on seams
- Thinning collar
- Frayed drawstrings
- Weak spots at stress points
Minor Repairs
- Small tears: Sew immediately with matching thread
- Loose threads: Trim or sew down
- Fraying: Use fabric glue or sew binding
When to Replace Your Gi
Even with perfect care, gis wear out. Replace when:
- Collar is thin and floppy
- Tears cannot be safely repaired
- Fabric integrity compromised (rips easily)
- Permanent odors despite washing
- Significant shrinkage from original size
- Competition illegal (too worn, wrong color)
Competition Day Care
- Wash 2-3 days before (not day of – needs to be fully dry)
- Inspect for tears, loose threads
- Check IBJJF color requirements
- Pack in breathable bag
- Bring backup gi if possible
Quick Care Checklist
- □ Wash after every training
- □ Use cold water
- □ No fabric softener
- □ Hang dry completely
- □ Store dry and ventilated
- □ Inspect weekly for damage
- □ Repair small tears immediately
- □ Rotate 2-3 gis if training frequently
Bottom Line
A quality gi washed and cared for properly can last 2-3 years of regular training. Neglect it, and you will replace it every 6 months. The 10 minutes you spend on proper care saves you hundreds of dollars and ensures you always look professional on the mats.
Your gi represents you – keep it clean, keep it fresh, and it will serve you well through thousands of rolls.
