If your driveway has old oil stains or you have just moved into a new home where the previous owner used to park their car on the concrete, cleaning oil off concrete is an easy task. Start by sweeping away any loose dirt or greasy spots. Then use a chemical cleaner designed for this purpose and rub the cleaner into the oil. Do not use water when doing this because the chemical cleaners can cause damage the concrete if it gets into it. You may also want to wipe the floor with a wet/dry vacuum cleaner to remove excess dirt.

Use A Stronger Detergent Solution

If you have any deep-seated stains, you may need to use a stronger detergent solution than what was used to remove the lighter stains. You may also want to try using a bleach-based cleaner or degreaser. Be careful with these products as they can harm or discolor concrete surfaces. These chemicals can also remove the protective sealant that is in cement.

Using Mild Dish Soap

A solution of mild dish soap and water can remove oil stains. Dab some dish soap onto a sponge and scrub the affected area. Only scrubbing the outer surface of the oil stain will cause it to come out. Try to remove as much of the oil as possible without actually scrubbing too hard.

Using a shop vac, remove any excess dirt or grease from the inside of the concrete. Then use your shop vac to suck up the excess air. When the suction reaches its highest point, it will suck up the remaining dirt or grease. This is the best time to use this solution.

Removing All Excess Air

Make sure that you are removing all of the excess air before sucking up the excess air. This is why you are using your shop vac for this job. After getting rid of all the excess air, you can start cleaning up the oil spots. Using a clean rag and a mixture of water and dish soap, gently scrub away the oil. Rinse the area well to get rid of any residue from the cleaning solution.

If the stain is too heavily stained to be removed by this method, you may need to use a stiff brush. Start by scrubbing the area in a circular motion. Then dip the stiff brush into a solution of hot water and clean the spot with it. Don’t scrub too hard as you may weaken the cement. Just dip the stiff brush into the hot solution and scrub away.

Rinse And Let Dry

The last step is to rinse and let dry. For stubborn oil stains, you may need to repeat the above steps. Be careful not to let the stain dry too long, as this can cause damage to the finishing surface.

So, how to remove oil stains from concrete? The first thing you need to do is to inspect the area you have to clean. If it’s in a heavily trafficked or used garage, you should consider cleaning the oil yourself. If this is not possible, ask a professional for assistance. They should be able to recommend a suitable cleaner for your garage.

You can make a natural poultice for the affected area by using Castor oil, coconut milk, and baking soda. Mix the ingredients and pour them over the oil stain. Leave it overnight and then vacuum. This is another effective method on how to remove oil stains from concrete garages. If it is still in the process of drying, you can apply a layer of polyurethane over it.

Final Words

If the stains are deep-seated, you should consider calling in a professional. There are many options available to remove grease spots like lemon juice, vinegar, and even toothpaste. But if all these seem too harsh for your purpose, you can use warm soapy water. Scrub the affected area thoroughly and rinse with water to get rid of the excess oil. After this, clean your concrete garage floor with a scrub brush.
