Preventing the Stains

Cleaning the stains is easy. But over time the build-up will rob your pristine bathroom of its luster. So, it’s better to invest in prevention. 

As a long-term solution, you can use a water softener system. Water softeners get rid of the Mg2+ and Ca2+ ions from the water in your home.  

One such system will cost you about $400 – $500. Additionally, based on the type of system you deploy you’ll also be incurring some variable expenses. 

These systems come in 2 forms. Ion-exchange water softeners replace the ions. This type of softener needs to be regularly refilled with salt. 

Salt-free softeners use potassium which crystallizes the Mg2+ and Ca2+ ions. They require potassium pellets. 

You can purchase one that suits your needs. Regardless of which you buy, it’ll be a good investment.

That covers everything you can do to remove and/or prevent hard water stains.


Question: What causes hardness in water?

Answer: The magnesium and calcium ions present in water cause its hardness. Groundwater flowing over limestone gathers these minerals. And that leads to hardness.

Question: Will the vinegar ruin my chrome faucet?

Question: Will vinegar get rid of mold?
