Apologies for the most boring question ever...
I like bed sheets that are patterned, and usually there's a lot of white in the pattern. If I wash them at 40, the white doesn't get clean-looking enough. If I wash them at 60, the colours fade. What's the solution?
I'm using biological washing liquid. I prefer to use the coolest temp I can (everything except sheets and towels goes at 30).
Thanks for any suggestions!
