- A blunt viral take—most BJJ academies are dirty—hits a nerve because it’s true too often: sweaty mats, bad airflow, no policy.
- The flashpoint centers on air conditioning and ventilation, space, and basic facility quality.
- Hygiene pros and top schools already publish rules; students can demand the same everywhere.
- It’s time for a Mat Health Code—a 60-second audit any student can use to grade a room.
‘Most BJJ Academies Are Dirty’—So Let’s Grade Them
The sport just got handed a gift-wrapped headline: most BJJ academies are dirty. Everyone has a horror story—sour mats, swampy locker rooms, summer classes with no air moving—and everyone shrugs because “that’s just BJJ.”
It isn’t. If we can rank brackets and belts, we can rank gym sanitation. Put the claim on trial with a scorecard and watch standards spike overnight.
The rant that lit up the timeline didn’t mince words:
“Almost across the board most jiu-jitsu facilities are too dirty… they’re too small, they don’t have the proper air conditioning.”
– Jackson Galka –
That line resonated because it named the silent killer: airflow. We obsess over technique trees and ignore the building.
In grappling—max sweat, skin contact, 90-minute classes—HVAC isn’t a luxury; it’s a safety system. Comfy rooms don’t just feel better; they lower skin infection risk when paired with mat cleaning and basic discipline.
Hygiene In BJJ: What Clean Actually Looks Like
Forget vibes. Clean has receipts—and the best rooms already say the quiet part out loud.
“Brazilian Jiu-Jitsu is gross… hygiene is stressed as a rule in most gyms—to try and salvage some sense of cleanliness from the abyss of grappling-based filth.”
– Soulcraft BJJ –
The gold-standard rules are boring and brutally effective:
“A clean gi, trimmed nails, and the absence of jewelry… are essential for keeping training safe, enjoyable, and professional.”
– Renzo Gracie –
Zoom in and you get the day-to-day checklist: shower, deodorant, nails, rashguard, wash the gi after every class, no jewelry on the mat, and mat/room cleanup that runs like clockwork.
“All students must maintain impeccable personal hygiene due to the close-contact nature of the art.”
– Renzo Gracie Academy –
Why so strict? Because the trade-offs are ugly when rooms get sloppy—staph, ringworm, impetigo, even HSV outbreaks can ride along with poor cleaning and packed classes.
“If a Jiu-Jitsu mat is not cleaned properly athletes may catch skin diseases. Staphylococcal infections, ringworm, impetigo, and herpes simplex virus.”
Put these together and the headline most BJJ academies are dirty stops being spicy and starts sounding like an industry audit we’ve been ducking.

A 60-Second Audit Any Student Can Run
Here’s the fun part—turn rage into leverage. Pin this to your notes and grade your room today. If your gym passes, shout it out. If it fails, send this to the owner and ask when it’ll be fixed.
The 10-Point, 60-Second Mat Health Code:
- Airflow & AC (2 pts): Is the room cool with steady ventilation during peak class? (Fans ≠ HVAC.)
- Mat Density (1 pt): Headcount appropriate for space, or are people tripping over pairs every round?
- Mat-Cleaning Log (2 pts): Visible log with disinfectant name, timestamp, initials? Twice-daily on heavy days?
- Uniform Rules (1 pt): Clean Gi/rashguard mandatory, sweaty gear banned from back-to-back classes?
- Nails & Jewelry (1 pt): Coach enforces trimmed nails, no jewelry—actually enforced, not just posted.
- Shower & Sink (1 pt): Soap stocked, hot water works, paper towels present.
- Foot Traffic Control (1 pt): Shoes stay off mats; walkways aren’t a swamp of gym bags and flip-flops.
| Score | Rating & Action |
| 9–10 | Elite — post it proudly |
| 7–8 | Pass — tighten up |
| 5–6 | Barely — fix this month |
| ≤4 | Fail — change gyms or demand change |
Now route it back to that headline. If most BJJ academies are dirty, this scorecard is the disinfectant. Students will compare notes, Instagram will do the rest, and owners will either tune the HVAC, buy proper disinfectant, and publish a log—or watch the room empty.
Owner playbook (steal this):
- Post the mat cleaning policy where cameras can see it.
- Name the disinfectant (and why you use it).
- Publish density caps for peak classes.
- Audit AC monthly before summer hits.
Make someone accountable every class (a rotating “mat captain” with initials on the log).
Grade Your Gym
The sport already learned to live in spreadsheets—training blocks, weight cuts, competition calendars. Hygiene is just another program. Run it, brag about it, and weaponize it in your marketing. If your room is cold, clean, and disciplined, say so loudly—your competitors won’t be able to fake it for long.
The bottom line is the only line that matters: the headline most BJJ academies are dirty doesn’t have to be true next month.
Publish the scorecard, fix the airflow, enforce the rules, and the mat becomes what it was supposed to be all along—a place where the only thing disgusting is your finishing pressure.
