Depends on what the shirts made of and its colour. If its all one colour, just dye it to match the background. No, you can get arrested in some States for that. My second cousin did 8 months for colouring in a Nike logo......just don't do it!
I would wash it inside out.
First, you take your arms out of both jacket and shirt. Then, just pull off your shirt.
There are not many ways to remove letters from a football shirt. You can however try to steam iron them off.

If you want to remove a shirt from what your wearing then go to [tops] then click the shirt that you are wearing then it will come off. When you want to put it back on click the shirt or[top] then it will put it on. same thing with all the other categories/
Although the (Pepperidge Farm) Goldfish t-shirt uses the Costumizer, it does not remove. You will have to replace it with another copied or purchased shirt.
I made my shirt by Silkscreening the logo in white paint onto a black shirt. :P

You could try burning it off with an iron, other than that, you can't.
