Scum build up on drum on Bosch washing machine?
There is a build up of scum on the outer side of the drum (maybe) due to use of too much detergent over the years. This causes smuts from time to time. The bearing is perfect.
I have tried white vinegar sometimes to clear it but no good. I don't want to strip the machine down if I can find a suitable cleaner that will clear it.
