This article will cover how to clean up an acid spill on your driveway or garage floor, as well as what you should do if the spill has already eaten through your surface.

So, How To Clean Up Car Battery Acid Spill On Concrete? Chlorine bleach can be put into a spray bottle. Spray the area that is affected and let it sit for five minutes before scrubbing it with a hard-bristled brush. If the stain remains, you can use another application of chlorine bleach and wait longer before scrubbing the surface again.

Once the stain is gone, rinse the area with water. If you are using a power washer to remove stains, make sure that it does not have too much pressure, or else it can damage your concrete surface even more.

It’s not often that you need to know what happens when battery acid is spilled on concrete.

But if it does happen, you’ll want to know how to clean up the mess and neutralize the acid before it causes any damage.

This article will walk you through all of the steps necessary for cleaning up a spill of battery acid on concrete, including identifying the type of battery fluid that was spilled, determining whether or not there are any injuries caused by contact with the substance, and finally how to remove stains from your flooring.

What Happens When Battery Acid is spilled on Concrete?

Aside from the potentially disastrous effects on the concrete, battery acid stains on concrete can be very difficult to remove. The surface of the concrete is porous and susceptible to staining.

There are many different types of acids in the world around us, but not all of them cause problems when they come in contact with cement – some even benefit it. Battery acid (sulfuric acid) is an example: if it spills on a cement surface like a garage floor or driveway, there’s no way to avoid harm coming to that area where this acidic ingredient touched down. It will change color and likely peel up or leave black-looking areas where it dribbled, ran off onto something else such as clothing or shoes which get soaked with this stuff.

Acid spills are ugly, smelly, and dangerous. They can eat through concrete, burn skin and corrode metals.

Fortunately, there are several ways to neutralize the effects of spilled battery acid before it does any damage.

The most effective method for cleaning up a spill depends on how much battery acid has been spilled, where it was stored when it was not in use, and what kind of material the batteries were stored in.

Our car batteries serve as the backbone of any vehicle. But, they also leak and spew out acidic compounds that can cause a big mess. How do we clean up spilled battery acid?

The best way to clean up a spill is to use club soda or baking soda and water mixture. It’s important to stay away from using rocks, sandpaper, hydrochloric, nitric acids, and bases like bleach as those may react with the environment where the spill occurred as well as your skin or eyes due to these chemicals’ high pH levels. Start by scrubbing down the concrete with soap and water first before continuing with this mop-up technique.

Let’s find out how to clean up a car battery acid spill on concrete.

Step 1

Put on your safety clothes. Bleach, battery acid, and muriatic acid are very dangerous chemicals that can hurt you if they get in your eyes or on your skin.

Step 2

Clear the area. Sweep the spill area with a broom to remove any loose dirt and debris.

Step 3

To clean up battery acid on your concrete you should use bleach. Mix the bleach with water to make a spray bottle. Then spray the area until it is all wet and let it sit for 5 minutes. Scrub away at the stains with a hard brush, but if it stays scrub again. After, rinse down any leftover spots or spots that are still wet with your hose.

Step 4

Set up a container to collect the water and make it not go into storm drains.

Step 5

Then, get some muriatic acid and pour it on the spill. Next, use a hose and rinse it off. Make sure that the water goes in the bucket or else it will make your driveway slippery!

Step 6

Use Baking soda. It will help to neutralize the acid that spilled on the ground.

Step 7

Take the water to a place that will recycle it.

Determine the type of Car battery you have

You have many kinds of batteries. Some kinds are alkaline, lithium, nickel-cadmium, or lead-acid. Lead-acid batteries, which are found in cars and motor vehicles, can be very dangerous when they leak. You’ll need to put them in a bag and seal it well before throwing the bag away.

If you have a non-car battery, you need to find out what type it is. Alkaline batteries are 1.5 volts and Lithium batteries are usually 3 or 3.7. They’re common in phones and other devices that can be recharged. Nickel Cadmium batteries are 1.2 volts and Lead Acid batteries are 2 volts, which is common in cars for starter motors.

The type of battery you have will determine how to properly dispose of it. If the device is rechargeable, such as a cell phone, then inform your local recycling center or municipality about the proper procedure for recycling the battery. This information should be widely available through your place of business. If non-rechargeable batteries are used, they should be recycled in a separate container from normal household waste.

DO NOT place a rechargeable battery into a trash receptacle or drain it onto the ground. Ingestion of these products can cause serious injury to you and possibly death to your pet if they get hold of one.

It Is Extremely Important to Have Safety Available

Normally, concrete is a tough material. It is hard to damage it. But acid can be dangerous for concrete too. Acid can make the surface of the concrete not look good and break down the surface.

Car batteries usually have acid in them. When the battery has acid on it, you should not touch it because it could hurt your skin. If you touch the battery and there is acid on it, wash your hands with soap and water.

When working with acid, it is extremely important to have safety available. If you do not use the right protective gear, you could get hurt by using dangerous chemicals like bleach or muriatic acid. The best way to avoid getting hurt is wearing long pants and good eye protection as well as opening a garage door so there can be proper ventilation if the stain is in a garage.


Cleaning up battery acid spills on concrete is best done with a mixture of baking soda and water. The acids in the battery can corrode metal, so it’s important to get them cleaned up quickly. This post has provided you with step-by-step instructions for how to clean an acid spill that has occurred outside your home or business property.
