Hey guys,
So on my 14/15 home kit, there are a couple of stains on it which have been there for a good 2 years now. It looks like dirt, but it has gone right through the fabric so we don't know what it is (of course, it had to be on the yellow...). Could even be permanent marker for all I know.
Anyway I have tried removing them with a few different products, but to no avail.
Does anyone have any quick and simple methods to get rid of stains like this?
