How do I remove black grease/ oil stain from white tee-shirt

Hello Aiden! There is no easy solution to removing grease or oil from fabric. That's because a lot depends on the amount of grease and oil, how long it has been on the shirt, and the type of fabric. The link I am providing gives quite a bit of detail on how to remove the stain. However my cousin owned a cleaners and he said it was far easier to remove stains from material that had not been washed . In other words if you try to get the stain out at home and it doesn't come out well taking it to the cleaners probably won't help because the stain is already set in via the washing and drying. Here is the link -- good luck!

I use either Soil Love or automotive hand cleaner, removes latex paint too.

Oh Aidan! Hello ;) and if it were ME I'd just go buy a new tshirt, LOL! but here is an article that tells you what to do. I just hope it will come totally clean for you and not leave anything behind ;)
