Saved my sanity
Live in the country on well water. Bowl staining is just a fact out here as water tables change etc. I used to stress terribly over the thin black ring I would get in the bowl. Tried every cleaner available, tried the vinegar and baking soda - none worked at getting rid of the whole ring.<br />On a whim I tried these. Holy smokes...in less that 1 minute of light scrubbing the toilet looks brand new. No scratching of the bowl at all.<br />I keep these in the pantry and have to hit the ring probably once every 4 months or so. Takes a minute. Stress gone.<br />Best bang for the buck I have ever purchased on Amazon.
