Bleached a stain on a white cotton t but...

[fussychica]

I treated a stain on a white cotton t with bleach and left it for a couple of minutes. Unfortunately i got distracted by a long phone call and only remembered the t shirt when it was over. The stain have gone but i now have a yellow mark which is bigger than the original stain. Any advice?

Once the yellow is there I don't think anything will get it out. I've done the same too.

Vanish gold. Wash it, then stick it in the sun. Worth a try before chucking it. Do not put it in the sun with the vanish gold on it, the yellow will become even worse (bitter experience!)

Thanks. Not an expensive t shirt thankfully, won't do that again!
