Yes. Every class, every time, no exceptions. If you train Tuesday and Thursday, that gi gets washed twice a week, not hung on a hook to "air out" for the next session.
This is the one rule about gi care that isn't up for debate, and it matters more here than in most places.
San Antonio doesn't do you any favors on this. Even heading into fall, our afternoons still sit in the eighties and nineties, and a gi that spent an hour soaking up sweat under those conditions is a warm, damp environment before you've even made it back to the parking lot. Skip the wash and you're rolling in that again next class.
Jiu jitsu is a contact sport in the most literal sense. Your gi presses against your training partners, the mat, and every grip they take on your collar and sleeves. Whatever bacteria your fabric picked up gets shared around the room the next time you wear it.
Skin infections are the thing every honest coach worries about, and clean gear is the first line of defense. It's not glamorous advice, but a washed gi protects you and everyone you train with. That's part of the respect side of martial arts nobody puts on a poster.
There's also the plain matter of smell. A gi that didn't get washed announces itself, and the person who has to grip your collar for six minutes will notice. Nobody wants to be that training partner.
Cold or warm water, never hot. Hot water shrinks the fabric and beats up the fibers faster, and a good gi is an investment you want to keep for a couple of years, not a couple of months.
Wash it inside out if you can, and skip the fabric softener. Softener leaves a coating that traps odor over time, which is the opposite of what you're after. A normal detergent does the job fine, and you don't need anything fancy or scented to death.
Here's the part people get wrong: hang it to dry, don't throw it in the dryer on high. Air drying is the single biggest thing you can do to keep a gi fitting the way it did the day you bought it. In San Antonio, a shady spot on the patio or a rack near a window will have most gis dry well before your next class.
Leave the belt out of the wash. There's an old tradition that washing your belt washes away your progress, and while that's more folklore than rule, the practical reason holds up: belts are thick, they take forever to dry, and they hold their shape better when you leave them alone.
If your belt genuinely needs freshening, a quick hand wash and a long air dry works. But it's the one piece you don't need to run through the machine every time.
A lot of adults wear a rash guard or compression shirt under the gi, and that layer soaks up even more sweat than the jacket does. It gets the same treatment: washed after every single session, air dried, no exceptions.
If you also train no-gi, wrestling, or Muay Thai on other days, your rash guards and shorts are doing the heavy lifting and pile up fast. This is where a second set earns its keep, which brings up the smartest move most people don't make early enough.
The single fix that makes all of this easy is a second gi. One in the wash, one ready to go, and you never have to time your laundry around the class schedule or make a damp-gi decision you'll regret.
For anyone training two or three times a week, a backup gi turns washing after every class from a chore into a non-issue. You wear one, wash it whenever it's convenient, and grab the other. That's the whole system.
If you're training on back to back days, the spare is close to mandatory. A gi that got washed the night before and air dried overnight is ready. A gi you're trying to dry in four hours between work and an evening class is a gamble.
At Pinnacle Martial Arts, keeping your gear clean is treated the way it should be, as basic respect for the people you share the mat with. New students sometimes worry they don't know the etiquette yet, and honestly, showing up with a clean gi covers most of it.
Nobody expects a brand new white belt to have all the details down. But washing after every class is the habit worth building from day one, because it's the one that protects the whole room. The coaches would rather remind you kindly than have you learn the hard way.
The rest of gi ownership follows the same spirit. Fold it, keep it out of the trunk of your car in this heat, and don't let it live in your gym bag between sessions. A gi that gets basic care lasts, fits, and never becomes the reason someone avoids partnering with you.
