Hi,
Recently, our washing machine has started causing our white sheets to have some grey marks on when they come out of the machine. They are like thin grey lines in creases, almost like something has left a residue. Maybe oil from the machine somewhere? Can the sheets get behind any seals anywhere, perhaps?
It only happens with our sheets, we've never noticed it with a normal clothes wash. We have used the Miele maintenance wash powder on a very hot cycle recently, and given the whole insides a good scrub down, to try and clear any problems, but still getting them.
Anyone had anything similar, or got any idea what it could be?
