The more I wash my duvet cover, the dirtier it gets....

[DELHI]

White, heavy cotton double duvet cover, a bit grubby I confess,[embarrassed] goes in washing machine yesterday and comes out streaked with grey/brown marks. I've now washed it 7 times, no kidding, and also run the washing machine empty at 95 degrees. The duvet cover is still covered in dirty streaks - any ideas?

Is the drain/filter on your washing machine getting blocked up?

Mine does this when it is not draining quickly enough and the gunk that is lurking down the drain seems to come back up.

No, Sarky, drain seems fine....

Wash the cover on a 95 degree prewash. I always do my white bedding on this and it brings it up beautifully. Definitely clean the filter on the machine too.

Oh, and make sure you use biological powder.

is the inside bit of the plastic seal to the door hiding some filth?

there must be some filth lurking somewhere...

Gunk on the door seal.It happens when you don't do a boil wash every few weeks.It then coats the sheets as you pull them out and leaves those streaks.Get in there with a cloth and you will see all the vile gunge! Clean it all out and then run another run a boil wash on empty with non-eco powder.The boil wash alone isn't enough to clean the door seal once the gunge is there. As to the marks-if you have washed the cover too hot you might have "cooked" them in,but a wash with eco-bleach and biological powder shifted mine off my white duvet.You may just be getting new streaks when you pull it out and are assuming they are the same ones.Once the gunge is off the seal you won't get any new ones.

thanks all. off to by bio powder and clean my seal....

You need to get right inside the foldy bit of the rubber seal. I was at the amount of gunk in mine.(slattern,me)

Also hang it out on the line to dry sunlight bleaches out the vast majority of marks from white bedlinen.
