I need to bleach some clothes white, they’re currently blue/green (long story, but my son has ASD and is very particular about a certain type of T-shirt that so far I’m unable to find in the correct colour). I’ve looked online how to bleach them but I can only find how to bleach whites to make the whiter, and a warning that standard bleach may damage the fabric. Once I’ve managed to bleach them, I plan to dye them his preferred colour and pray they will be accepted! Can anyone advise me please?
