Getting out sweat stains?

[Radagast]

I have a gi (Arawaza Black Diamond) I have worn about 12 times - only for gradings and tournaments. But it is getting yellow-brown sweat stains around the collar already. I've tried shout and oxy clean sprays/powder, and mixing up a Borax paste. Does anyone have any other suggestions?

(Yes I did a search, the newest thread was almost 10 years old so new thread rather than necro... and there might be new solutions since then!)

Thanks

Hey Radagast, I was going to say OxiClean, but you said you've tried it. Just to make sure, did you try taking a scoop of the powder, putting it in a bucket with water, and letting it soak for 6+ hours? And then washing it? You probably have, but I wanted to mention it.

Since you have put so much effort into it, have you happened to go to a professional cleaner or a dry cleaner and ask for their thoughts? It might be worth paying for a cleaning to "reset" the gi, more or less, and then you can work on maintaining it from there.

I would take it to a cleaner. Cleaners are pretty inexpensive, just do some research to make sure that you're taking it to someone who looks trustworthy.

I agree that it sounds like you are in need of a professional cleaner.  I've done that a few times for blood stains.  

To avoid problems such as sweat stains in the future, I suggest not working so hard.
