does your gi get dirty from sweat, my gi around my neck gets a brownish stain around it from my sweat, does any of yours do the same?

Mine does not, but others' do. You could try washing your neck before class. lol just kidding.

Mine Did Even Though I Have A Shower B4 Hand, Dont Worry Mate Ur Not Alone

I use white viniger to keep it white.

what all works for cleaning the sweat marks? does any one know

Somtimes it's just the reaction between your sweat and the canvas material itself.

but does anyone know how to clean it?

You could try soaking it in a bath of cold water with some soap powder in it. It got the mud out of my suit.

 

Do not use bleach.

Oxy-clean! My uniform doesn't get stains, but my boyfriend's does. I use Oxy-clean and it works wonders .... for him anyways. We have hard water, so if we use bleach, our whites turn yellow, and the Oxy-clean (or anything similar) will remove it after a few washes. Or a good soaking in cold water and Oxy-clean does the trick

Geez, thats a good advice. i just wish to know what a Oxy-clean is. lol
