BJJ Hygiene: The Complete Guide for Grapplers
Most BJJ hygiene advice stops at "shower after training." That's not enough.
If you train regularly, you're exposing your skin to dozens of people, hundreds of mat contacts, and a warm humid environment where bacteria thrive. A shower 30 minutes post-training is too late for some of what landed on your skin during the roll.
This guide covers everything — what to do before you step on the mat, what to do the moment class ends, how to keep your gear clean, and what the weekly routine looks like for a serious grappler.
The Three Biggest Hygiene Mistakes in BJJ
1. Waiting to shower
The window between finishing training and getting clean is when bacteria have the best access. Your skin is warm, slightly damaged from friction, and often has small cuts or mat burns. The longer you wait, the longer pathogens sit in those entry points.
2. Not treating the gear
Your gi, your rashguard, your shin guards — all carry everything you picked up on the mat. A gi worn twice without washing is a petri dish. Headgear padding holds bacteria for days. Your gym bag is constantly re-contaminating whatever you put back in it.
3. Treating hygiene as reactive
Most grapplers only think about hygiene when they get infected. By then, they've already missed a week of training. The goal is to make hygiene a habit that runs in the background — so you almost never have to think about infections.
Before Training
- Trim your nails — short nails mean fewer cuts on your partners and fewer places for bacteria to hide on you
- Cover any open cuts or mat burns before you roll — medical tape works well
- Don't train with an active skin infection — ringworm, impetigo and staph are all highly contagious
- Optional: apply HOCl spray to any open or healing mat burns before training
Immediately After Training (The Critical Window)
This is the most important part of the protocol.
- Spray exposed skin with 300 PPM HOCl — do this before you even get changed. Neck, forearms, elbows, underarms, face if you're doing no-gi
- Let it sit — don't rinse, don't wipe. 60 seconds is enough
- Shower within 20 minutes — soap and water, full body
- Check your skin — look for any new red spots, bumps or mat burns while you're in the shower
- Apply HOCl again to any mat burns or cuts post-shower

Gear Hygiene
Gi
- Wash after every single session. No exceptions.
- Hot wash when possible (60°C / 140°F kills most pathogens)
- Dry fully before storing — a damp gi in a bag grows bacteria overnight
- Own at least two gis so you always have a dry one
Rashguard and shorts
- Wash after every session, same as the gi
- Hang to dry — don't fold into a bag while damp
Headgear and shin guards
- Spray the inside padding with HOCl after every session
- Let air dry — don't pack away while damp
- Wipe down the outside with a damp cloth weekly
Mouthguard
- Rinse with clean water immediately after use
- Store dry in a case — not loose at the bottom of your bag
- Replace every few months or after any illness
Gym bag
- Spray the inside of your bag weekly with HOCl
- Let it air out after training — leave it unzipped overnight
- A bag that smells bad is already growing bacteria. That smell means something.
The Weekly Routine
| Task | Frequency |
|---|---|
| Wash gi and rashguard | After every session |
| Spray gear padding with HOCl | After every session |
| Check skin for new spots or infections | After every session |
| Trim fingernails and toenails | Weekly |
| Spray inside gym bag | Weekly |
| Wash training shoes | Weekly |
When to See a Doctor
Hygiene prevents most infections. It doesn't prevent all of them. See a doctor if:
- A red bump is growing or spreading, warm to the touch and painful
- You have a ring-shaped red patch on your skin
- Any skin infection hasn't improved after 3–4 days of basic treatment
- You develop a fever alongside a skin infection
- You've had more than two staph infections in a year
Don't tough it out. Don't train through it. See a doctor, treat it properly, and come back clean.
The Bottom Line
BJJ hygiene is not complicated. The basics take less than five minutes per session and they work. The grapplers who stay healthy train more, improve faster, and have longer careers.
The ones who skip the protocol end up on antibiotics, off the mats, and back at square one.
Make it automatic. Spray, shower, wash the gear. Every time.
