Corsodyl mouthwash & brown stains

[GCH]

Weirdly I never had this problem at all when I used it in the past, but this time it is atrocious, mainly around the edges of teeth, progressively worse the further back in the mouth you go.

Any suggestions for removal? Mildly abrasive toothpaste? Baking soda? Something else (aside from an expensive visit to the hygienist of course)?

Horrible stuff... tastes foul, stains your teeth and kills your taste buds.

As I have discovered...
I only ever used it in the past for a few days before - this time it was for a couple of weeks.

It is in the trash now. Never again!
