How to Remove Acid Stains from Marble Floor


How easily and effectively you can remove acid stains from marble tiles depends on the etch marks type. If the stains are fresh, removing them may take less time.

On the other hand, if you need to remove old stains, you may need to do some elbow grease for effective results. So, you must need to choose the method wisely!

Ways to Remove Acid Stains from Marble Floor

There may have been an accident involving your toilet bowl cleaner or battery acid that has caused etching on your beautiful marble floor. No matter how the stain got there, you want it gone!

So, here I will share some of the best and most effective methods with you by which you can get rid of those etch marks forever!

I have divided the acid removal methods into two categories: household cleaners and commercial products. Let’s look at both and pick the best suit for you!

Taking Help of Household Cleaners

Household cleaners have always come to our rescue, be it for spills or stains. And when it comes to removing acid stains from marble surfaces, they are also quite effective.

Method 1: Baking Soda and Water Paste

Baking Soda and Water

One of the most common items in home remedies is baking soda. You can either sprinkle it on the stain directly or make a paste to scrub away the stain. But how do you know when to sprinkle and when you need to make a paste?

Well, if the stain is fresh, then go for sprinkling. In this case, you just need to sprinkle a generous amount of baking soda over the acid marks and wait a few minutes. If the soda starts to bubble, it means it is working.

After a few minutes, just wipe the floor with a damp cloth, and the stain will be gone! It helps to neutralize the fresh stains of acid by reacting.

On the other hand, if the stain has been there for some time, making a thick paste of baking soda will be more effective. To make the paste, all you need is water and baking soda. Simply mix two tablespoons of baking soda in half a cup of water to form a thick paste.

Use this cleaner to cover the stain and let it sit for about an hour before scrubbing with a brush. Rinse the area with clean water, and your floor will be as good as new!

Method 2: Use Borax

If you are dealing with fresh acid stains, Borax is one of the best things that you can use to remove them. Simply make a paste of Borax and water, and then rub it onto the stain using a soft cloth.

Now wait for a few minutes, and then wipe it away with a cloth or paper towel. You may need to repeat this entire process a few times to completely eliminate the stain.

Borax can be a genuine alternative to baking soda in this regard. You just need to monitor the removal process carefully. If you don’t have this cleaning agent at home, you can buy it from most stores that sell laundry detergent.

Method 3: Diluted Ammonia

Baking soda should be the first thing you use. But if you’ve already tried that and the stain is still there, the next thing you should try is diluted ammonia. You can create a diluted ammonia solution by mixing one part water with one part ammonia.

Once you have your solution, simply apply it to the stain using a clean cloth. Let it sit for about 15 minutes.

Rub the cloth onto the affected area in a circular motion. Rinse the area with clean water and dry it off. You will notice that the stain start to disappear. Repeat this process as necessary until the stain is gone completely.

Using Commercial Cleaners

After household products, commercial cleaners are always an option when it comes to how to remove acid stains from marble surfaces. You can buy these cleaners from any hardware store or even online. Just make sure the commercial product is safe to use on marble and follow the instructions on the label.

Method 4: Marble Restoration Kit

A marble restoration kit is another way to remove stains from the marble surface. These kits have everything you need to safely and effectively clean your floor. You will find it online or collect it from harware stores.

You will find the etch-removing product that is specially made for marble. You can use commercial product like Fila Marble Restore Kit as it can be your best bet. So, buy one and follow the instructions properly to get the job right.

Method 5: Marble Polish Water

To get rid of etches, marble polish is the best thing you can use. You can find this at any hardware store, and it comes in a tube. It is easy to apply, and perfect polishing only requires one coat.

Simply put on rubber gloves, apply polish to the etch with a clean cloth, let it sit for about five minutes, then buff it off with another clean cloth. If your etch is really bad, you might have to repeat this process a few times.

No matter what method you choose, removing acid stains from marble floor is possible. Just take your time, do some research, and find the best method for you. Good luck!

Some Pro Tips for Removing Acid Stains

  • Before applying a basic solution, you should not moisten the area with water since the water will reactivate the acid.
  • Because of the glossy finish, scrubbing hard with baking soda might harm the surface.
  • If you do not have baking soda near your hands, you can use Borax instead.
  • When using ammonia, wear gloves and ventilate the area well. Be careful about ammonia safety
  • If you want to ensure the job is done right, hiring a professional marble restorer is always an option.

Frequently Asked Questions (FAQs)

Q: Does Vinegar Harm Marble Surface?

Using acidic substances on marbles can harm the surface. It can eventually scratch it or lose shine. That’s why experts recommend no vinegar on marble surface. So, always use pH-neutral cleaning agents for marble flooring.

Q: Can You Use Hydrogen Peroxide on Marble Floor?

To use hydrogen peroxide to remove an acid stain from marble surface, simply pour it onto the stain and scrub with a brush. This may take a few attempts to get the best results.

However, you can use hydrogen peroxide with a light-colored marble tile floor. Don’t even think to use it on dark color marble, as the bleach in it can discolor the surface.

Q: How Do You Remove Oxidation from Marble?

There are a few distinct techniques for eliminating oxidation from marble. You can use a poultice, which is a powder that you mix with water to create a paste. Spread the paste onto the stained area and let it sit for 24 hours before rinsing it off.

Poultice powder is excellent for removing stains that are caused by oxidation, but it might not be as effective on other types of stains. If you’re not sure how to remove a particular stain, it’s always best to consult with a professional.

Another way to remove oxidation is to use a chemical stripper. It is a more aggressive method and should only be used as a last resort. Chemical strippers can damage the marble, so read the instructions carefully before using one.

Q: Can CLR Be Used on Marble?

CLR is such a versatile product, isn’t it? You can pretty much use it to clean anything and everything. But the big question is: can you use CLR on marble?

The answer is… maybe. It depends on the type of marble you have. If you have soft marble, then using CLR is a definite no-no. The chemicals in CLR will just end up damaging your floors even more.

However, if you have hard marble, you might get away with using CLR – but only as a last resort. Most professionals don’t recommend using CLR on marble because it is too harsh of a cleaner. It can etch or damage the marble surface.[1]

Q: Why Does Marble Turn Orange?

Marble turning orange results from an acidic substance coming into contact with the calcium carbonate in the stone. When this occurs, a chemical reaction happens, resulting in the marble’s surface changing color.

Remember that patience is a virtue, and you must proceed slowly. Rome wasn’t built in a day, and neither will your marble floor be.
