we have got a ten year old AEG washing machine, and black mould seems to
have penetrated into the light grey rubbery-plastic door seal. Is there
any good way of removing this black stain please? Thanks.

After 10 years, you will soon need to replace the door gasket
(if available.) After removing the old one you can clean thoroughly
(with chlorine) the groove that secures the gasket.
