Washharder

Corner Supply makes personal care and cleaning products for martial artists — and for the academies that raise them. Gi wash, mat cleaner, and skin defense that keep up with how often you actually train.

First batch, first dibs. No spam, ever.

What we make

The wholeroutine

Mat to shower to gym bag. Three products, each built for one job it does properly.

Gi & rashguard wash

Breaks down sweat, oil, and bacteria without wrecking the weave. Your gi comes out clean — not perfumed, not stiff, not grey by month three.

Mat & academy clean

A daily-use mat disinfectant built for a room full of bare feet. Gentle enough to wipe down between rounds, ruthless on everything living in the vinyl.

Skin defense

Post-training body wash and a barrier balm formulated against ringworm, staph, and mat burn. The stuff you should have been using all along.

After every session

Three minutes,mat to door

Most skin problems in a gym start in the gap between training and getting home. Close the gap and they never start at all.

Step OneGear straight inGi, rashguard, belt — into the wash the same day. Never back in the bag damp.
Step TwoSkin within the hourShower before you eat, not after. That first hour is the window that actually matters.
Step ThreeMats before closeOne pass over the mats every night. The academies that skip it are the ones with outbreaks.

The first batch is close. Put your name down and we’ll send word the day it’s ready — academies first.
