How to Remove Battery Acid Stain from Concrete [5 Effective Ways]

It’s almost a frustrating fact that some battery acid puts a terrible impact on your concrete floor. Your garage floor has to be the victim most of the time for holding the disgusting stain of the battery acid. The more irritating fact is that the stain behaves so stubborn that, sometimes it doesn’t go off only by some minimal washes with water and soap.

After the battery acid stain is cured, the common question of how to remove battery acid stain from concrete in some effective ways comes into the head. It requires some harsh chemicals to make itself remove from the concrete floor for sure.

Though after adopting the right chemicals, the stain can be removed, still it requires much awareness of the dangerous effects of the chemicals.

The orange and yellowish stain makes the concrete floor looks helpless. Therefore, today we need to learn the ways of cleaning the battery acid stain effectively.

What Will Neutralize Battery Acid on Concrete?

Though concrete comes with a high density and a low chance of deterioration, it gets affected by the battery acid stain. As the acid contains sulfuric acid, it pervades the stain on the concrete surface quite fairly. It even amalgamates with the components of concrete and embodies the bonding of the stain. This bonding needs to be neutralized to abolish the stain from the concrete.

However, several substances and degreaser products are capable of neutralizing the acid swiftly and satisfactorily. Let’s talk about them.

F9 Concrete Rust Remover:

F9 concrete rust remover is the strongest substance that is made solely to remove and neutralize battery acid stain. This remover clears out the cured stain of battery stain without hampering the concrete-made surface.

It removes the orange shades of the stubborn stain and leaves a layer of resistance to rust and corrosion. From thick stains to fertilizing stains, this F9 concrete rust remover knows how to impress the user y removing them with its amazing formula. For a professional-like service, adopt this remover at once.

Here is another acid rust remover for concrete stone and masonry surfaces:

Baking Soda:

Baking soda is the best way to neutralize battery acid on concrete. As this product carries sodium bicarbonate, it works effectively on the stain. Besides, baking soda can be used as a paste or you can simply sprinkle the substance on the battery acid stain.

This alkaline chemical has a great impact on hydrochloric or muriatic acid. Also, lead-acid battery spills caustics that are horrible to withstand. With the mixture of water, baking soda works like a game-changing paste on the affected area. Besides, it acts so instantly and ferociously that it will not take much time to accomplish the job.

Vinegar:

Vinegar has the strength to neutralize battery acid but it’s certainly not as powerful as the paste of baking soda and water. Still, vinegar saves you from the alkaline battery acid stain. It reacts strongly on batteries like these and can be of great help.

For mild application, the treatment of vinegar is quite appreciable. Besides, it works finely when you add lemon juice to it. Use the vinegar solution when the battery acid stain is still not cured because then it will even withstand muriatic battery acid as well.

Chlorine Bleach:

Chlorine bleach as a solution for neutralizing battery stain is effective and caustic at the same time. It emits chlorine chemicals that make it hard to breathe. It’s because chlorine bleach is caustic itself and when it comes to the acid of a battery, it becomes more active.

Therefore, some precautions are needed when you adopt the substance to clear away battery acid. Without the precautions, your lungs might get affected seriously for a long time.

Ammonia:

Ammonia can react directly on battery acid to neutralize its action. As most of the battery acid contains sulfuric acid, it reacts with ammonia instantly. Then the reaction creates ammonium sulfate which is easier to remove from the concrete.

Ammonia, as a starting process to remove the stain of battery acid, works as better as baking soda. It also helps in preventing the corrosion of the stain. However, ammonia affects purposefully when the battery acid is not dried yet.

11 Steps to Remove Battery Acid Stain from Concrete:

Battery acid leaves a terrible stain and it comes with different orange shades. These shades look super odd on the concrete floor and do not go with the concrete base. Muriatic acid stain is that kind of stain which leaves you to think about how to remove it from concrete. Also, how to remove battery water stains from the floor is another popular question that is asked by people. Let’s see the ways and steps of removing battery acid stain from concrete.

Step 1: Collect Your Necessities:

Removing the stain of battery acid is not a very easy task. The acid of the batteries can be explosive and horrifying. Therefore, you need to be all prepared to battle the stain in the right way. Let’s see the materials you need at once,

1. Goggles
2. Protective Hand Gloves
3. Well Clothing
4. Mop and Clearwater
5. Hard-Bristle Brush => CheckOnAmazon
6. Chlorine Bleach => CheckOnAmazon
7. Baking Soda => CheckOnAmazon
8. High-Pressure Hose => CheckOnAmazon
9. Paint Scrapper => CheckOnAmazon

Step 2: Sweep the Place:

The next thing is to mop the affected floor with fresh clear water. As battery acid is not a very charming thing, sweeping the floor with bare hands might be sickening. Therefore, sweep the concrete floor with the help of a mop and clear out all the dust and debris.

Step 3: Spread Chlorine Bleach:

Before spreading chlorine bleach, wear your suits, hand gloves, goggles for safety issues. Then pour chlorine bleach into a bottle that has a nozzle and spray setting. After that, spray the chemical over the battery acid stain properly.

That’s how you can clean up car battery acid spills on concrete. However, make sure the affected area is covered with the spray.

Step 4: Let It Soak:

After spraying the substance, wait at least 5-10 minutes. Within this time, the bleach will loosen the acidic bonding of the stain and let the particles come out from the bonding. Wait till 5 minutes pass, and be patient about it.

Step 5: Scrub the Area:

After the acid soaks the bleach chloride, you need to scrub the affected area. As the stain will behave still stubborn, you’ll need a hard-bristle brush to scrub the stain. Don’t mind scrubbing the place with maximum effort because the concrete can withstand the pressure because of its hardness.

Step 6: Reapply the Whole Procedure:

After the hard scrubbing procedure, the battery acid stain should be removed from the floor. Rinse the place with a hose and see if the stain is gone already or not. However, most of the battery acid doesn’t go away that easily after it is cured. In this case, you need to reapply the whole procedure.

Spread the chlorine bleach on the same affected area again. But this time, let the substance set on the area for more time than before. Then scrub the place with a hard-bristle brush as before rinse the place with a high-pressure hose and see how much stain has left the area.

Step 7: Set for the Next Process:

If chlorine bleach cannot remove the battery acid stain, then you need to move to our next plan. In our next plan, we suggest you collect a container that will hold the runoff water from the affected area. This container is needed because the runoff water will be hazardous and it might affect other unaffected areas and storm drain.

Step 8: Make a Paste:

The next job is to make a paste using baking soda. As we’ve already discussed the value of baking soda in neutralizing battery acid stain, using the substance for the job will make no loss. To make the paste, you can add water or lime juice to some extent. But there is a chance that lime will solidify the bonding of the stain. Therefore, water should be enough to make the paste.

Step 9: Apply the Paste:

After making the paste, apply it properly to the affected area. Use a paint scraper to do the job. Make sure you are covering all the space properly. Let the paste work and wait till it stops bubbling in the spotted location.

Step 10: Scrub the Place and Clean It Again:

When the bubbling of the paste has stopped, it’s time to scrub the place again. Use the same old bristle brush or you can use a wire brush for a more effective result. Then use the high-pressure hose to clean the place and make sure the runoff water goes right into the container.

Step 11: Clear the Residue:

After the cleaning with baking soda solution, there will be residue on the concrete. This residue will be removed if you use a quality cleaner. It will provide a better result if you use an ammonia-contained cleaner for the job. This will be enough to make your concrete look like as fresh as before.

Warning: The container with hazardous water should be to a recycling center of hazardous material. As it can carry heavy metals like lead or copper, don’t throw it away in places where there are children or pets.

Ways to Clean Concrete with Concrete Rust Remover:

Cleaning a concrete surface with a rust remover is easier than any process. But you’ve to be careful with that too because some rust remover comes with harsh chemicals that help to eat up the concrete and sometimes strip the concrete from the plaster.

Therefore, you need to use mild removers and apply them wisely. These removers also help to remove golf cart battery acid on the garage floor. However, let’s see the cleaning process.

Step 1: Adopt WD-40 Degreaser Product:

This product is really helpful for its versatility. It penetrates profoundly to the stain and rust helps to break down their internal bonding. Therefore, adopting the product is a very wise idea. Spray the wd 40 Degreaser on the area carefully so that it covers every affected spot.

Step 2: Wait and Scrub:

After spraying it, wait for some minutes to let the product react on the spot. Then scrub the place in a back and forth motion with effort. Then rinse the place with clear water.

Step 3: Apply the Product Again:

One application is never enough to clean the concrete. Therefore, apply the product again and go through the same whole process one more time. This time, you’ll get a clearer view of the concrete surface.
