We have a Zanussi WDJ1285 and after many years of good use it has started to put stains on all type of material. We use Surf Liquid and have done for a long time. The machine has been cleaned even a wash with special liquid. Door seal is has been cleaned inside the creases. Hot wash with a handful of soda has been tried. Lint filter and powder draw is clean. The stain seems to show the holes of the drum as clear with the stain all around it. Cannot upload pictures shown up as to big. TerryR
