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 claiming that such-and-such a solution or product will rid your toilet of the dreaded ring; some even without using 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.

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 moves through the ground and into our waterways. Along the way, this water picks up minerals such as calcium, magnesium, and lime.

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 using more energy due to the mineral buildup left behind.

Supplies Needed

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 if 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: (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 Barkeeper’s Friend and sprinkle it inside your toilet.
  4. Wearing the gloves, gently yet firmly, begin scrubbing away 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.

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!

Yay! Sparkling CLEAN toilets! 

Seriously, though, that’s all it took. So easy.

    AMAZING!! I have tried so many things for my toilets to look brand new and this was perfect! Took hardly any time to remove the hard water buildup and now all 5 toilets sparkle. I even cleaned my kitchen sink with BarKeepers Friend and it removed some minor stains. It looks brand new too! What else can I clean?!? Lol! THANK YOU!!

    Simple instructions. Was not sure of Dry wall Sanding Screens but will ask at Lowes for it. Very interested to try the process as I have tried all the other things listed in the summary with no success.

    Thanks for the details on how to remove the stains . We had very bad staining and barkeepers friend,
    which I had used before to remove hard water on my kitchen faucet and then vinegar afterwards,
    only removed part of the stains. When I also used the drywall sheets and used lots of pressure I was finally able to remove the rest of the staining. Thanks so much.

    OMG! You are a lifesaver! Thank you, thank you, thank you for posting this!! I was really about to give up and buy new toilets when I happened upon this post! We have a whole house water softner but still getting those nasty rings in the toilets. Go figure! Thanks for sharing your discovery!!!

    Outstanding fix! We purchased a house that has been ‘let go’ and used as a rental , with horrific hard water deposits in the toilets. I’ve tried everything from acid washes, Pumice stones, to any cleansers on the market…nothing worked. In one day I had sparkling clean toilets..like new!
