I've just got a load of the next size baby clothes out of the loft and a lot of them are covered in this mysterious brown staining.... see pic.
They were clean when I put them there, and stored in a vac bag (although the vacuum may have gone fairly early on by the looks of things).
I've put them in the bath to soak in vanish so fingers crossed they're salvageable. I just want to know what happened so it doesn't happen again.
Any ideas?
