Just what is it? I wash on a 60 I use vanish but it's still there!

Mould?

It looks like mildew. You get it if you put laundry away slightly damp. Washing it at 60 degrees should have killed the mould but it can leave a stain. Try hanging it in the sun to bleach it out.

Mould oh no! I've noticed it on some of the others too. We don't have a tumble dryer. So have to hang things on the radiator. And although it's hot now some times it takes a few days to dry. I will have to do better at keeping on top of it I think. Thank you for your replies

If you can, get a clothes airer for the summer months.
