Does anyone know how to clean gunge from the seal of a washing machine, have tried hot water and tried to rub it off but no luck. Any ideas would be appreciated. tia
If it's partly black .. you will not get it all off. It's very rubbery, so will stain permanently eventually.
Spray in the folds (I presume you are referring to the main door seal) with Flash kitchen or bathroom, or rub with Jif cream cleaner.
Be careful not to rub too vigorously or pull it about because you may damage the seal. While you may find the mark left there unsightly, it really does no harm - most machines aquire one within a year or two.
