Hygiene Etiquette for New White Belts

Nobody hands you a hygiene rulebook on day one of BJJ, but there is one — and following it is how you get invited to roll rather than quietly avoided. I remember picking these up the hard way as a white belt, so here are the unwritten rules, spelled out. General information, not medical advice, and not about any product we sell.

The white-belt hygiene code

• Turn up clean. Shower beforehand if you can, and definitely don't roll up straight from a sweaty day at work without a thought.
• Clean kit, every session. A fresh gi or rashguard each time — never pulled from a damp bag. See rashguard hygiene.
• Short nails, hands and feet. Check before class — see hand and nail hygiene for grapplers.
• Shower soon after — the post-training shower routine covers it.
• Don't share towels or water bottles.

The big one: stay home when you should

If you've got an undiagnosed or contagious-looking skin issue — a spreading rash, a crusted sore, a patch that could be ringworm — don't train. Tell your coach and get it checked. This is the rule that protects everyone, and it's covered in full in when to stay off the mats. Hiding something to get a roll in is the fastest way to lose the room's trust.

A few more unwritten ones

• Mind your breath and your feet. You're going to be very close to people, so brush your teeth and wash your feet before class.
• Wash your belt too. The "never wash your belt" thing is gym folklore, not a hygiene strategy.
• Tap early, tap often. Not strictly hygiene, but injuries become entry points for skin problems, so don't be a hero in your first month.
• Tie long hair back and keep it clean — otherwise it ends up in everyone's faces.

Why it matters

Grappling is intimate, sweaty and contact-heavy. Good hygiene isn't fussiness — it's respect for the people you train with, and it's the quickest way to fit in. Get it right and you'll be the partner everyone's happy to drill with; get it wrong and people will suddenly be very busy whenever it's time to pair up.

The bits nobody quite spells out

Beyond the obvious, a few habits mark you out as someone people want to train with:

• Air your kit, don't fester it. The moment you're home, get the gi out of the bag and into the wash or onto a hanger — a damp bag is how the smell and the problems start.
• Bring your own everything. Towel, water bottle, tape. Borrowing is how things get shared that you'd rather weren't.
• Deal with niggles. Cover cuts and blisters before training; an open graze is an open door, and covering it is just considerate.
• Match the room. Every gym has its own norms — watch what the experienced players do with footwear off the mat, where they put their kit, and how they handle a skin issue, then follow suit.

None of this is about being precious. It's the difference between being the new person everyone's happy to help and the one people quietly avoid pairing with.

Common questions

Is it really that big a deal as a beginner?

Yes — arguably more so, because you're building your reputation in the room from scratch. The good news is it's all easy stuff: clean kit, short nails, a shower, and honesty about skin issues. Nail those and you're already ahead of plenty of people.

What if I can't shower before class after work?

Do what you can — a quick wash, deodorant, clean kit, and definitely clean feet — then shower properly afterwards. People understand a busy schedule; turning up genuinely grubby session after session is what gets noticed.

Do I really need to wash my gi after every single session?

Yes. One session, one wash — a gi worn for a hard roll is damp with sweat and has been all over the mat. Re-wearing it is how kit starts to smell and how problems spread.

Everyone says don't wash your belt — is that real?

It's a superstition, not hygiene advice. Your belt drags across the same sweaty mat as everything else, so wash it like the rest of your kit. Whatever "tradition" you've heard, a clean belt has never lost anyone a match.

How do I tell a partner their hygiene is a problem?

Tactfully and privately, or quietly through a coach if it's awkward — coaches would rather know. Most people simply haven't been told the unwritten rules yet, exactly like you're learning them now, so assume good intentions and keep it kind.

What should I do with my gi between back-to-back sessions?

If you're training twice in a day, ideally rotate to a second clean gi rather than re-wearing a sweaty one. If that's not an option, at least hang it to air properly rather than stuffing it back in the bag, and wash both as soon as you're home.
