What causes the black ring below the toilet rim?

Before jumping to the solution to remove the stain from the toilet bowl, you must find out the culprit for this problem and why it needs to be solved—let us discuss the reason for any spot in the bathroom. 

  • Lack of pure water:

Now, Most states in the USA can not provide fresh water in the washroom and kitchen. And the level of minerals and chemicals in this water is more than in normal water. When you use hard water, it reacts with the material of the bathroom. So It leaves a stain on those places, and it’s getting darker day by day. It’s nearly impossible to differentiate hard water from normal pure water. But ordinary water contains fewer minerals like calcium, magnesium, iron, lime salt, etc. than hard water, And the black, brown, etc., color stain on the toilet rim, the bowl is the result of the reaction of calcium and magnesium salt with the toilet.
