7 Best Toilet Bowl Cleaners For Hard Water


Having hard water is a hassle, we know because we also have it in our home – but it’s actually a problem that the majority of US households face. Those white spots metal and glass are the first telltale signs that you are dealing with hard water, if you don’t deal with the problem you eventually get a nasty build-up of scale on faucets and fixtures.

Toilets are also harder to keep clean with hard water. The mineral deposits from hard water can eventually clog up the “rim jets” – the holes under the rim of the bowl where water comes out when you flush, over time that blockage can lead to less powerful flushing. Some hard water also contains high levels of iron that leaves reddish rust-colored stains on your white porcelain toilet bowl. 

Luckily the widespread problem of hard water has lead manufacturers to come up with solutions and there are now plenty of bathroom cleaning products that are specifically designed to combat the ill effects of hard water, here are our top picks that work well on porcelain toilet bowls.

Best Toilet Bowl Cleaners for Hard Water

Scrubbing Bubbles Toilet Bowl Cleaner

Scrubbing Bubbles Toilet Bowl Cleaner

Let’s start the list with one of the highest-rated and recommended options for toilet bowl cleaning.

The Scrubbing Bubbles Toilet Bowl Cleaner and Power Stain Destroyer is, as its name suggests, quite powerful in removing stains.

Testing the product out, we noticed how the green liquid formula started changing to a more bluish hue color. This transformation was an indication of the cleaning substance doing its magic on stains like rust and limescale.

Leave the cleaner as is and let the toilet bowl absorb the liquid solution for about 15 minutes. Afterward, we noticed a significant difference in the surface quality of the toilet bowl as we started scrubbing and rinsing the formula off.

Some of the features we liked about the Scrubbing Toilet Bowl Cleaner include the bottle’s extended neck design, which makes using it under the toilet bowl rim as easy as 1-2-3. We also commend this product with its ability also to remove not only limescale buildup but also rust. That said, we noticed that it took several treatments to remove some of the more persistent stains.

All in all, the Scrubbing Bubbles Toilet Bowl Cleaner certainly delivers on its promises, and we highly recommend this product for those who are in dire need of a cleaning solution for toilet bowl stains.

Alternatively, Scrubbing Bubbles also offers a toilet bowl cleaner in tablet form. The Continuous Clean Drop-In Toilet Cleaner Tablet provides a more convenient option as it helps treat the hard water within the toilet bowl’s cistern.

Megabrite Toilet Bowl Cleaner

Megabrite Toilet Bowl Cleaner

The Megabrite Toilet Bowl Cleaner has a distinct liquid solution that reminds us of those facial scrubs with tiny abrasive grains. The thick gray liquid incorporates small abrasive beads that assist in scrubbing the toilet bowl’s surface better.

Along with that added feature, this gel is best for treating hard water stains and limescale buildup on various surfaces, from stainless steel to porcelain. This aspect of the Megabrite Toilet Bowl Cleaner also means you can use it to clean bathtubs as well.

In addition to its impressive cleaning properties, the Megabrite gel solution also incorporates a biodegradable formula that utilizes plant-based ingredients and essential oils. This quality makes this toilet bowl cleaning solution a fantastic eco-friendly option.

Some nitpick we have revolved around the squeeze-type bottle. The thickness of the gel made it difficult to quickly pour the proper amount of cleaning solution onto the toilet bowl. There is also no instruction on the label, which is quite weird.

As for Megabrite’s strengths, we loved how the gel solution has a tinge of peppermint scent which smells quite lovely and relaxing. The formula used in the cleaning gel solution also makes it safe to use for septic tanks. The extra-thick gel also allowed Megabrite to stick to a specific part of the bowl without dripping off.

Overall, Megabrite is undoubtedly worth a shot for those still looking for a reliable way to clean and remove hard water stains on their toilet bowl.

What is Hard Water?

Calcium Deposits – Telltale sign of hard water.

Hard water is a very common issue, actually, 85% of households across America have hard water.

So, what exactly is hard water, and how is it distinguished from its counterpart, soft water? The amount of magnesium and calcium primarily determines whether it is defined as hard water. Higher levels of these minerals found mean that it is hard water while soft water tends to have a higher sodium concentration.

While hard water does not pose any risk to our health, it can cause issues regarding our household – specifically in the kitchen and bathroom.

Signs You Have Hard Water

Several not-so-subtle signs point as to which hard or soft water flows through your pipes. Here are the things that you should look for to determine if your home uses hard water.

Faint, smoky, white spots on glasses and silverware. 

One of the most common signs that your home has hard water is if your drinking glasses and silverware start developing spotty white stains on the surface. These stains are calcium carbonate buildups left on dining wares not appropriately dried after washing.

Clothes and fabric color fading.

Due to the high concentration of minerals in the water, clothes and other fabrics tend to fade and wear out faster. There are also occasions wherein light stains will be left on your clothes after a spin in your washing machine.

A gradual decrease in water pressure.

Mineral deposit buildups within the pipes are also an issue with hard water. Notice your water pressure starts weakening. One probable cause might be the buildup of minerals that shrinks the pipes’ interior diameter, leading to a noticeably weaker flow of water from your faucets.

Effects of Hard Water on Your Toilet Bowl

Toilets are also not immune to the damage that hard water can inflict over time. Based on the signs we listed above, your toilet bowl might not flush properly if a considerable buildup of minerals blocks this feature.

Visible dark stains might also start appearing around the toilet bowl, which is incredibly hard to remove with just your standard toilet bowl cleaner.

Well, this is where we come in. Below, we have compiled a list of the best toilet bowl cleaners for handling hard water stains. These products are specifically designed to cancel the adverse side effects caused by hard water on your toilet bowl.
