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.

    This does indeed work very well! I have also found that you can use 1500 to 2000 grit wet sandpaper like they use in body shops to get rid of just about anything too. You can find it on Amazon for next to nothing.

    Thank you so much for this trick. I have lived in my home for 10 years and have tried everything. I have always been embarrassed when company comes over. Not anymore due to this wonderful trick. Thank you for sharing, providing the instructions, and product links. I truly appreciate it!

    1. Jessica Randhawa says:

      Thanks for the feedback, I am happy to hear this fixed your ten-year-long toilet ring problem 🙂

    Thank you—this worked like a charm! I didn’t have fine Sheetrock screen, so I gingerly used a medium screen instead. The bowl looks new again!

    I tried everything before and nothing worked. This method worked like a charm and looked like new again! I went very light on the pressure because I was still concerned about scratching up the surface. Thank you for sharing.

      Thanks for the feedback Gabe 🙂

    I tried everything else but this worked so well with very little effort.

    1. Jessica Randhawa says:

      I am happy it worked for you Julie, thanks for the kind feedback 🙂

    Omg omg omg! It absolutely worked and with little to no effort. I used this method in my sink and bathtub as well and worked just as great! Thank you so much!

    1. Jessica Randhawa says:

      I am happy to hear that this worked for you Brianna, thanks for the positive feedback 😀

  7. James a Salva says:

    I had tried baking soda, vinegar and TOFIX in cleaning the hard water stains in my toilet. Instead of clearing the hard water stains, it left a dark blue stain where the hard water stains used to be. Do you have any suggestions on how to clear this “CHEMICAL STAINS”.

    1. Jessica Randhawa says:

      Hi James – if the stains are the blue dyes from the chemicals on the hard water, then the stains will come off by following the directions in this post 🙂

  8. Kathleen says:

    How do you prevent the toilet from restaining? We have well water. I have removed the stains in the past, but shortly afterwards it restains.

    1. Jessica Randhawa says:

      Great question Kathleen! I have not found a way to prevent hard water stains from forming. All the many different types of products I tried that went in the toilet tank did not work for me.

      I wish I had a solution, but for those of us with really hard water, there doesn’t seem to be any good fix or hack short of setting up an entire house water softening/filtering system.

  9. Bethany says:

    Can I use liquid bar keepers friend? Or just the powder? (Trying to not have to buy a bunch of new stuff)

    1. Jessica Randhawa says:

      Either liquid or powder will work great, Bethany 🙂
