It is probably relevant that the bathroom is fed with softened water so there will be no scale inside the cylinder or pipes.
I am guessing that it will be from the copper pipes but I don't know how to clean it off.
this is not the bright green dribble you sometimes get from a dripping tap or recent plumbing. there is no limescale anywhere.
Instead it is a very faint and slightly mottled film that you can only just see all round the basin. I suppose it is where soap scum might be if the bathroom wasn't very clean. It seems to start above the "low" water level where you might wash your hands and goes right up to overflow level.
I wondered if it might be the green household detergent that has been used to swab round the basin and bath, but I would have expected that to swab away with hot water and a sponge.
It is not scaly or rough. It can (with considerable rubbing) be reduced using a housheold cleaner and a white nylon scourer.
I can't see any such stain in the WC or bath.
I haven't yet tried it with a limescale cleaner as there is none in the house (never normally required)
Any ideas?
