The basic toilet bowl cleaner is a wonderful help. What i like to do is to put some on the toilet bowl. Wait for 10 minutes then come back and clean it. It's a great help. Cleans well. It also leaves a great smell.
My number one product to use on my toilet bowel. It removes the calcium and any other hard water cleaner. And I can use it about one a week and just use another cleaner for everyday usage if I have company coming. No harsh smells when I use it. Go pick it up it works
