Hard water can be found all over bathroom surfaces including showers, sinks, faucets, and, worst of all, the toilet. Unattractive and extremely frustrating, the last thing any one of us wants is to host a holiday party with a toilet that looks as if it hasn’t been cleaned for months.

You’ll find countless cleaning products available and even more blogs and websites out there claiming that such and such solution or product will rid your toilet of the dreaded ring; some even without the use of chemicals at all.

Most of these claims are false, I’m sorry. I know this from personal experience because I promise, before learning about this trick from my friend at The Home Depot, I had literally tried everything.

This trick works so well, in fact, that it will almost look like you went out and bought yourself a brand new toilet! But don’t take my word for it,

I run an apartment complex, where unfortunately people don’t know how to clean their toilets, I thought I was going to have to replace the toilet, but I was able to clean the toilet and it looks brand new. This will save me tons of money, and time, it literally only took me two minutes to clean the hard water stains. -Kali

Difference Between Hard and Soft Water?

Hard water: that which contains an appreciable amount of dissolved minerals such as calcium and magnesium.

Soft water: that which contains less dissolved minerals. Or, when treated, the only ion it may contain is sodium. Naturally falling rainwater is soft water, for example.

How does water become hard? Water becomes harder as it makes its way through the ground and into our waterways. Along the way, this water picks up minerals like chalk, lime, calcium, and magnesium.

Given that hard water contains essential (and super important) minerals one may wonder why we soften our water when it’s hard. 

Hard water is tough on appliances (dishwashers and washing machines, for example) and is hard to clean. Making it less effective and uses more energy due to the mineral buildup that is left behind.

Supplies Needed to Clean Hard Water From Toilets

Before I say anything else, I thought it important to mention that the toilet that you see pictured in these images is “clean”. This includes the before and the after images.

In other words, I cleaned the toilet with actual toilet bowl cleaner before removing the hard water ring.

Anyway, I Googled, “how to remove toilet bowl ring”  or “how to remove hard water stains from the toilet”. Everything I found led me to some cleaning product or a pumice stone.

Since Home Depot is Octavian’s favorite store in the world, we headed there. So that we could spend as much time as possible in the gardening equipment aisle, I asked a nice man who worked there where I could find the pumice stones. Then I asked him pumice stones actually remove hard water rings from toilet bowls.

He stopped me right there.

No no no no no pumice stone, he said. Too much risk of scratching the porcelain. 

Thank goodness, this toilet angel from Home Depot had a better idea – Fine-Grit Drywall Sanding Screens. YOU GUYS, this man saved my toilets!

Here’s how you can save yours.

How to Remove Hard Water Stains from Toilets (Step-By-Step)

  1. Gather all of the necessary supplies.
  2. Put on a pair of rubber or latex gloves and cut 1-2 small square pieces from a sheet of Fine-Grit Drywall Sanding Screens. Set them aside.
  3. Carefully open the Barkeepers Friend and sprinkle it inside of your toilet.
  4. Wearing the gloves, gently yet firmly, begin to scrub away at the hard water buildup in a circular motion with the Drywall screen. Don’t press TOO HARD. Our goal is to remove hard water stains, not destroy the porcelain.
  5. Continue until all of the built-up hard water stains have been removed.
  6. Flush.

Removing Hard Water Stains from Toilets – What Doesn’t Work?

  • Bleach
  • Toilet bowl cleaner
  • Vinegar solution overnight
  • Those tabs that turn your toilet water blue
  • Baking soda
  • Borax and vinegar

None of the above worked. In fact, I later learned that bleach may make toilet rings caused by hard water worse – or even permanent!

    Are you able to use sandpaper instead of sanding screens? And if so, what kind do you recommend?

    1. Jessica Randhawa says:

      I do not recommend sandpaper at any grit, as you will probably end up with scratches on the porcelain, instead of taking off the hard water.

      The dry wall sanding screens are worth a trip to the hardware store or waiting for delivery ๐Ÿ™‚

    After months of seriously contemplating just getting a new toilet, this worked so well and so easily! I let the Barkeeper’s Friend sit for a few minutes first and I hardly had to scrub. Thanks!

    Oh my goodness, thank you! Finally, something that worked! I wish I’d taken before and after pictures. My hard water stains were horrendous; long dark vertical streaks all around the bowl. It took some effort but my toilet is sparkling clean. Thank you so much!

    Finally! Those awful hard water stains in my toilets are gone! Thank you! I have two old porcelain coated cast iron bathtubs. Years of hard water has left impossible to remove yellow stains in the bathtubs. Would this method work on yellow hard water stains?

    1. Jessica Randhawa says:

      Possibly, but I would test it first in a hard-to-notice area to make sure before diving in… you want to make sure your porcelain-coated tubs are as strong as your toilets ๐Ÿ™‚
