I did a silly thing

[skimask]

So I was wondering if someone could help me out, I washed my work uniform the other day and I didn't check if the washing machine was empty 🙄 there was a couple of black flannels in there and now the white lining of my uniform is a grey/ purple colour and the light blue colour is dull and slightly grey and I need it to be white again! What do I do to get it back to how it should be?? TIA

You can buy colour run remover in the supermarkets.

I’ve had good success by following the colour run remover with net curtain whitener
