Our neighborhood has a community well with very hard water.
Even with a water softener we get hard water stains on the toilets.
The stains always make the toilet look unsightly and always appear dirty.
I have discovered an easy way to get rid of the stain around the water
line of the toilet.
Waterproof sandpaper works great to rid the toilet of the unwanted ring.
It is very easy to do. Just turn the water off at the back of the toilet and
flush until the water doesn't rise to the water line. With a small square of the
sandpaper scrub until the ring is gone. Turn the water back on and flush.
It is a dirty job so wear gloves.
Every time I do this I am amazed that my toilet looks brand new again!
