HELP-How to bleach a powder blue shirt with bleach stains already present?!?

I accidentaly used a bleach pen to try and get the stains out of my concert shirt (with emblems on it). Now there is no way to get the blasted stains out, and I've decided to bleach the entire shirt. But I don't know how it will effect the shirt or what to use to bleach it.

Sodium Hydrosulfite is the color stripping agent we mentioned when we asked you to consider removing the color from your garment and redying it. It's safe for the environment, and it's extremely effective. It might just be ecologically safe equivalent of chlorine bleach. Rit Color Remover is a good example of such a product.





After removing the color, if you decide to use a different color, then just choose one from the Rit collection.
Reply:If possible, remove the emblems and get some blue dye and dye it back...........You will bleach the emblems too......they should be easy to put back with a needle and thread,,,,,,,,
Reply:DON'T bleach the whole thing. I did this once and it eventually the shirt fell apart from what they call "bleach rot" and the decal got dry and crackled. My daughter's friend accidentally got bleach on hers. We took it outside and used a squirt bottle to spray droplets all over it, let it sit a few minutes (15 or so) and then washed it. It had a speckled, unique look to it.
