Ring around the Toilet

I have had a ring around the toilets in my house ever since we moves in 2 years ago. I have tried many thing to get rid of it but nothing has worked. Mackenzie Pew said I need a cleaner with an acid in it. I found this stuff with packaging right out of 1974. I thought I would give it a try. It is a powder and I used it with a green scrubby and I got it all off!!! I was so thrilled I has Eric come and see it. I had to use gloves it burns your skin but it works. It is silly I am so thrilled about this but I am and I want to share.
