How to remove oil stains from concrete surfaces

​I think we can agree on this: oil stains are an eyesore on your driveway, garage floor or patio, no doubt. (Maybe not the one above with the pretty rainbow colors, but you get the idea.) Getting rid of them isn’t always easy, so let me explain what I learned from experience and found on the Concrete Network, which seems to live and breathe everything to do with concrete.

The Problem with Oil Stains

If you were thinking of covering up those oil stains with paint and/or a sealant you will be disappointed. Oil tends to seep back through to the surface and will ruin your new anticipated look. You have to handle that stain before engaging into any beautification project for that particular surface.

Note that concrete is a porous building material and thus will absorb stains. The size and age of an oil stain matter. The older the stain, the harder it is to remove it. So, don’t wait but treat any stain as fast as possible. To avoid this situation altogether, we recommend a regular resealing of your concrete surfaces every few years. Driveways, patios and walkways will be protected and restored to like-new appearance. If you are interested in this service, please contact us here or give me a call at (813) 992 7243


Removing oil and grease stains from concrete surfaces

Even professional contractors have to admit: Removing oil and grease stains may take some trial and error to find the best method for your situation, but we have some tips for you.

1. Clean the oil and grease away with a strong detergent, and a scrub brush (or sponge). You’ll find these products in a hardware store or online. This method is working well on small spots and spills.
   
   
2. Use a concrete cleaner or an alkaline degreaser in combination with hot water. Let the chemical sit for about 15 minutes before power washing the area. The hot water lifts the oil from the concrete, and the degreaser emulsifies the oil so it can be flushed from the surface.*
   
   
3. Use a poultice to break down the oil and suck it from the concrete. You can use cat litter, sawdust or other absorptive material. Soak it with a strong solvent, smear the material over the stain and cover the poultice with plastic. The solvent will break down the oil, and the absorptive material with suck it out of the concrete. Works best on small stains.
   
   
4. Apply single-celled microorganisms that thrive on crude oil and eat it up. When the oil is devoured, the microorganisms die, leaving the concrete clean and oil-free. This process is sped up by sunlight and is the preferred method in our Florida climate. Ask me for more information.

Any of these methods are recommended and will be finished by a thorough pressure washing.


Take caution when using commercial concrete cleaners or degreaser*

Using chemicals is the more aggressive method of attacking those pesky oil stains. They are most effective on porous concrete which hasn’t been sealed yet or has no hard or dense finish. Make sure to read the instructions on the product and use with care. 

When using bleach or chlorine for cleaning, make sure to never mix them with any other cleaning solution or liquid except cool water. Mixing them with household cleaners can produce toxic fumes which are a health hazard.


Removing oil stains from concrete surfaces before selling your home

It makes sense to get those unsightly stains removed, before you put your house on the market. Concrete surfaces with embedded oil or grease stains are creating a dingy look and lower the perceived value of your home.
