Removing Hard Water Stains from a Toilet

Removing hard water stains from the toilet is one of the most challenging aspects of cleaning a toilet. With the right approach and cleaning products, success is possible.

These tips will help you remove hard water stains from your toilet.

  • Supplies: You need these supplies on hand—white vinegar, baking soda, a pumice stone, rubber gloves, and a toilet brush.
  • Empty the bowl: Flush the toilet to reduce the water level. If there are stains above the waterline, turn the water supply off and flush to empty the bowl completely.
  • Add vinegar: Pour enough white vinegar into the bowl to completely cover the stained areas.
  • Give it a rest: Let the vinegar soak and do its work for 30 minutes to an hour. The vinegar will efficiently break down mineral deposits and stains.
  • Give it a scrub: Use a toilet brush to give the stained areas a good scrubbing. When using vinegar and scrubbing while cleaning a toilet, the stains should start to disappear. You can also dip the brush in vinegar while scrubbing to produce better results.
  • Add baking soda: If the vinegar doesn’t fully get rid of the stains, sprinkle baking soda on the ones that remain and let it sit for up to 10 minutes. Since baking soda is mildly abrasive, it helps remove the remaining stains.
  • Give it another scrub: Scrub the bowl again with a wet toilet brush, paying attention to the baking soda areas.
  • Rinse and repeat: Flush the toilet to rinse away the vinegar and baking soda. If this doesn’t completely remove the stains, repeat the process or consider using a pumice stone.
  • Use a pumice stone: For particularly stubborn stains, you may need to use a pumice stone. Cleaning a toilet with a pumice stone is straightforward, but you need to be careful not to scratch the porcelain. Wet the stone and rub it against the stains lightly. Don’t scrub too hard, or you might scratch the porcelain.
  • Regular Maintenance: To avoid hard water stains in the future, regularly use a toilet bowl cleaner designed to combat hard water deposits. This will help prevent hard water stains from forming.

How to Get Rid of Toilet Ring

The steps for how to get rid of a toilet ring are similar to removing hard water stains from a toilet. You can use vinegar and baking soda, as described above, to remove hard water stains.

Another option for cleaning a toilet with a toilet ring is to use lemon juice and Borax. Squeeze the juice from a lemon covering the toilet ring. Then sprinkle some Borax powder on the ring. Let the toilet sit for a few hours. Scrub the ring with your toilet brush. Flush to remove the mixture of lemon juice and Borax.

You can also use a pumice stone to get rid of a toilet ring. Wet the stone and rub it over the ring, being careful not to apply too much pressure, which could scratch the porcelain surface. Continue rubbing until the ring is gone. Flush to rinse away any residue.

Getting Rid of Limescale in a Toilet

While the tips for how to get rid of limescale in a toilet are similar to those for hard water stains and toilet rings, limescale buildup is also difficult to remove. The steps above for using vinegar and baking soda are a good starting point for limescale removal as well.

Instead of letting the vinegar sit for up to an hour, however, you will want to let it sit for several hours or even overnight for best results.

Another way to remove limescale in a toilet is by using citric acid. Citric acid can be found in powder or liquid forms. Follow the instructions on the product carefully to know how much citric acid to use. Dilute the acid with water and pour it into the bowl, making sure the limescale is completely covered. Let the acid sit for several hours or overnight. Scrub the bowl to watch the limescale disappear. Flush the toilet to rinse away the citric acid solution.

If vinegar and baking soda or citric acid don’t work, you can also rub away the limescale with a pumice stone. Be careful not to rub too hard, or you risk scratching the porcelain.
