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!

    Can I use this application in the sink which is porcelain and bathtub and sides of bathtub where the water stands after showering. The bathtub is NOT porcelain? It’s a poured tub and wall.

    1. Jessica Randhawa says:

      I think it should be fine on the porcelain sink but test a small, less noticeable section first before going all in. 🙂

      I would not try it on your tub.

    Seriously … this IS, without a doubt, THE BEST solution to this situation

    Our house is about to be listed. We have five bathrooms – all toilets are stained at the water rim (we are on a water well system out here in the country, so not on “city water”)

    I sprinkled Bar Keepers around the rim of water line and let sit for 30 minutes… then cut a one inch square of fine drywall sanding screen for each toilet

    It literally took less than five minutes for each toilet. I tried everything else, but this is the OBSOLUTE solution !! Unbelievable!

    Thank you sooo much !

    Using the fine 3M drywall screen removed the stains in my toilet. I recently moved into a home with 2 toilets that have brown stains in the well. It looks like someone tried to clean those stains without success. It looks like they scratched the finish of the toilet also. I haven’t been able to find my drywall screen yet, but I noticed I had some fiberglass window screen that is very similar to the fine drywall screen. Do you know if the drywall screen is the same material as a fiberglass window screen?

    1. Jessica Randhawa says:

      The scratches were probably from the previous owner/occupier using a pumice stone or something besides 3m drywall screens.

      I do not know about fiberglass window screens, so I do not want to advise wrong at the risk of you scratching your toilets.

      You can buy 3m Drywall Screens at Amazon here 🙂

    OMG! I too live with hard water stains since moving to Arizona. I’ve tried EVERYTHING!! I was so embarrassed and tired of looking at this brown ring, that was only getting worse. I just happened on your site and rushed out to get these products. The employee at True Value showed me these screens come in 12×12 sheets for $2. The ring came off easily, but the water marks on the north and south sides of toilet took about 15 mins more of scrubbing before they too were gone. The employee told me she has to do this about every 2 weeks to maintain. If you know of something else for maintenance, lmk. Thank you thank you thank you!!!
