We had a guest who tried to help by putting a wash on with my lovely, expensive, high thread count white superking bedding and also had the absence of mind to pop in a bright turquoise tea towel for its first wash - now everything is bluey-green.
They then put the whole lot in the tumble drier so by the time I got home everything was nice and hot.
I've bought everything I can (Ace bleach, colour run protect, whitener) but nothing has worked.
Is there something I've missed that might work?
