How do you remove rust looking stains from toilet bowl?

plain coke

Many have used those foaming tablets used for cleaning dentures with good results. Worth a try, I got mine from DollarTree.

When commercial cleaners and the many diy recommendations like cola- Tang - koolaid or toothpaste did not work for my toilet hard water stains/ discolored ring my go to solution was the pumice stick.

This is excellent way to remove stains and rings in the toilet.

Great for thick crusted calcium mineral discolred ring build up that the toilet waterbowl collects.

They are found at my local Walmart for less than two dollars -good for multiple uses. Be sure to follow the use instructions, soaking the pumice stone in water for a few minutes. While the stone is soaking, grab your toilet brush and splash water up around the ring. Note: It’s very important to keep both the stone and the surface wet while cleaning to avoid scratching your porcelain.

All you need

I had to use this product when we had a well with a lot of iron in the water. It worked great. It is available at Walmart.

Iron Out works, when nothing else does.
