dh now has a very heavy canvas gi for karate.
He sweats alot when he does karate, and was advised that the canvas gi would be better.
But the last 2 or 3 weeks it's come out of the washer with brown sandy marks on it. I try to clean the washer before he washes the gi, so it's a mystery what is happening, altho he is wondering whether it's grease from his skin which collects in the creases of the stiff canvas as it washes.
He's currently trying to scrub the marks off at the sink.
It's driving me bonkers, trying to work out what the cause is. He's going for grading in a couple of weeks, so he needs to get the gi properly clean for then...
