To get grass stains off clothes...

Use some milk... full fat, semi skimmed or whatever. I think there are some enzymes or something but it always worked a treat on my karate gi.

It's a load cheaper than the latest nonsense too.

Cheers for the tip Joe, does it work on any fabric.. i guess karate gi is probably nice cotton is it not?

[Squidders]

well, the karate gi, as you say, is thick cotton but milk is actually pretty friendly stuff on most things. I used to just rub milk in then stick it in a normal wash... job done.
