Cleaning Blanco Silgranit sink
What about it?
Our two year old Blanco Silgranit sink has these stains on it that I think are from our hard water. I’ve tried the Silgranit cleaner and it doesn’t work. Thinking it is a hard water deposit I tried vinegar and also CLR to try to dissolve it which didn’t work either. Any advice on how to get these marks out?
