How to remove manganese stains from toilet

Removing manganese stains from toilet is one of the top concerns of many homeowners. If you are sick and tired of those ugly and revolting stains on your toilet, don’t miss the chance to read this guide on how to say goodbye to these ugly marks in no time.

What is manganese made of

Manganese is one form of mineral that can occur in rocks, sediment, and soil. It is beneficial metal that can be found in different types of fruits, grains, and vegetables. Although it is an essential nutrient that should be part of the human diet, this is no longer considered healthy if consumed in high amounts in water.

Manganese is usually present in deep water wells and there are even wells with as much as 3 PPM of this mineral. Even a small amount of manganese can already damage appliances and cause staining around the house. It is also common to find iron and manganese together. These two metals usually mix to form some staining of deep brown color and many other kinds of negative effects around in your home.

The evidence of manganese can be predominantly seen in the dishwasher since most detergents raise the pH levels of water, allowing manganese to turn solid. Aside from this, you can also see this metal floating on the toilet water’s surface that gives it a brownish tinge.

Manganese metal has two main forms. The most common one is manganous manganese and the other is manganic manganese. The former is manganese in completely dissolved form. It is the type of manganese that needs precipitation before this can become filtered from water.

The latter is a form of solid manganese allowed to precipitate. A water filter can remove the precipitate metal although manganous manganese is best removed using water softeners.

Does manganese stains

Yes, manganese stains. You might have been caught by surprise if you have ever tried removing the lid to the toilet tank and you notice what looks like staining or black water. You might have also seen dark or black staining in the shower or dishwasher. Whatever the case is, it is never pleasant to look at these stains, not to mention that removing them can be nuisance.

These problems are the result of the mineral present in the water known as manganese. While it is not necessarily an emergency to see manganese stains from water, but when at high levels, this can affect the quality of drinking water, appliances, plumbing, and laundry. Manganese minerals tend to leave some deposits that can accumulate in plumbing and restrict water flow over time.

What does manganese stain look like

Manganese is a metal that can leave stains. The mineral can leave a tea or brown colored stain on dishes, laundry, and fixtures that is different from rust stains unlike iron. Manganese is a mineral that can also create ring-like black stains in toilets. Removing manganese stains from the toilet may take some cleaning solutions and a little elbow grease.

What does manganese smell like

Manganese can make water smell like asphalt or oil. It also tastes bitter like that of petroleum and asphalt.

What can remove manganese stains

You can remove manganese stains using paste made of hydrogen peroxide and cream of tartar. Let this stand before rinsing off.

How to get manganese stains out of toilet

There are three methods you can try for getting manganese stains out of your toilet.

If you will use cream of tartar paste, here are the steps you need to follow:

1. Pour one cup cream of tartar in a bowl. Add ¼ cup hydrogen peroxide. Combine this solution properly until you form a thick paste.
2. Apply this paste on the manganese stains in your toilet. Use a toilet brush to rub this on the manganese stains. Try applying the paste on the stains as thick as possible.
3. Let the paste sit for around 15 minutes. Scrub on the manganese stains using a toilet brush.
4. Flush your toilet to rinse away the cream of tartar paste and enjoy a toilet bowl free from stains all over again.

The second method you can try is to use white vinegar and baking soda.

1. Get a bowl and fill this with one cup baking soda. Add ¼ cup white vinegar to it to form a mix. Make sure that you pour the vinegar in little by little since the mixture may foam up fast.
2. Apply this paste mixture on the toilet stains with a toilet brush or sponge.
3. Let the paste sit on the manganese stains for 15 minutes.
4. Flush your toilet to rinse the paste away.

The third method is to use water and trisodium phosphate.

1. Fill the bucket with one gallon of water. Add 2 to 4 tablespoons of trisodium phosphate that you can find in both liquid and powdered forms in many home improvement stores.
2. Pour all this mixture in the toilet bowl then let this sit for 15 minutes or up until you remove the stain.
3. Flush your toilet to rinse off the trisodium phosphate.

Manganese stains FAQs

There are many other things you need to know about manganese stains.

Different water treatment solutions are available that can be used for effective removal of manganese from your drinking water. These methods will also have different results depending on the form of metals and the concentration of the manganese.

Since manganese is more of an aesthetic problem, this has a higher chance of harming water consumers. After testing the water and identifying the type of manganese found in the water supply, you can eliminate it with the use of several water treatment systems.

Does reverse osmosis remove manganese?

Yes, reverse osmosis removes manganese. Reverse osmosis is among the most popular and common options for water treatment that can help remove a plethora of impurities. More often than not, it is also thorough enough to allow the removal of pretty much anything.

A reverse osmosis purification system has several filter stages that help ensure the effective treatment of the water. These stages of filtering include activated carbon filter cartridge membranes, post-filter membranes, and sediment filter cartridge membranes.

However, the semi-permeable membrane is the main star of the show that can be found in all types of reverse osmosis systems. Reverse osmosis membranes contain tiny pores that serve as the sieve. Every time water is being pushed through the membrane, the extremely tiny water particles are the only ones that can pass through. This leaves the lingering contaminants within the chamber where they are flushed away together with the wastewater.

RO filtration systems are an effective option for water treatment overall for high concentration of the removal of dissolved manganese and dissolved iron, particularly if you love the idea of the system that also offers purification and reduction of a variety of additional contaminants such as hydrogen sulfide, lead, chemicals, aesthetic impurities, arsenic, VOCs, and bacteria.

Does Brita remove manganese?

No, filters like Brita cannot remove manganese in un-precipitated state. Although softeners will be able to serve as filters for the precipitated manganese, these are still poor filters even at their best.

Does boiling water remove manganese?

No, boiling water does not remove manganese. The truth is that boiling water for a long time will only evaporate some water but will cause the manganese molecules as well as other elements and metals to be more concentrated.

Does activated carbon remove manganese?

Yes, activated carbon can remove manganese. Activated carbon powder can be effective when it comes to manganese removal. This is also appreciably regarded as the most feasible, economical, and versatile adsorbent for manganese removal from aqueous solutions. 

Does Aquasana remove manganese?

Yes, Aquasana may be able to remove manganese. All of drinking systems of Aquasana have been NSF-certified for removing up to 99% of lead as well as 67 other contaminants such as asbestos, chloramines, herbicides, industrial solvents, mercury, pesticides, PFOA and PFOS, pharmaceuticals, and other VOCs or volatile organic compounds.

Does a water softener remove manganese?

Yes, a water softener can remove manganese. Water softener systems are the preferred method to reduce hardness in water. However, this can also be a very efficient solution when it comes to removing small traces of manganese and even other metals.

The process of water softening uses ion exchange resins and at this point, calcium and manganese get substituted with sodium. The backwashing process is then implemented afterwards to get rid of the manganese and the rest of the metals from the filtering resin used for water softening.

Does Zero Water remove manganese?

Yes, Zero Water removes manganese. When tested according to the protocol of the NSF based on the 40 gallon filter that is twice the rated filter, Zero Water can remove up to 98% of manganese present in tap water.

Does Pur Filter remove manganese?

No, Pur Filter may not be able to remove manganese. There is no information indicated on the official Pur Filter website that the product can help when it comes to manganese removal.
