Bleach stained towels

[Pleatedforehead]

My daughter has accidentally got bleach type stains on lots of our towels-it took me a while to realise what was happening as I thought I must have accidentally sprayed bathroom cleaner on a few when I first noticed them in the wash then I realised it was always the hand towels from the bathroom beside her bedroom.
She had been using a face wash for teen skin with benzyl peroxide and that appears to be the culprit, it wasn't completely rinsed off and was ending up on the towels. She has switched to a different wash now but I am left with a load of towels with bleachy parches on.
I know if I use dylon it will still come up patchy, considered putting them all in a bucket with bleach and trying to achieve a more uniform colour first but think they may be past salvation.
Any ideas mumsnet brains??

Bleach them first so they're uniform, then dye them a nicer colour?
Bleaching will make them a weird pinky colour which won't be very attractive

I'm going to have to just try that as they can't look much worse than they do now!

In my experience one bleaching doesn't mean uniform. I'd be inclined to dye them with the original colour and if that doesn't pass the test dye again. Of course you'll spend so much on it that it might not be worth it.
