How to Remove Grease Stains from Concrete

Concrete is one of the most stable and preferred forms of flooring in most outdoor locations. Whether it is your driveway, patio or garage space, concrete is an ideal choice due to its unbeatable strength, rigidity and longevity. In addition, sweeping off the dust from concrete is relatively easy. Still, the cleaning process gets a bit complicated in case of an oil leak on the driveway or when you accidentally end up dropping some grease on the patio grill. Just using soap and water won’t be enough to get the concrete back to its original glory. If you wonder how to clean grease stains easily, here are some simple remedies that can help you out.

Baking Soda

We have heard multiple benefits of baking soda over time, from baking cakes to cleaning greasy stains in the kitchen. Due to its abrasive nature, baking soda helps dissolve grease and dirt stains from the grit surfaces, thus making it helpful in scrubbing off oil stains from the concrete. Take some baking soda and spread it evenly over the stained portion. Now, let it rest for nearly half an hour. Take a scrubbing brush, dip it in warm water and apply some soap to it. Scrub the floor with the soapy brush till the stain is gone. Rinse with water and let the concrete dry.

Vinegar

Vinegar is another kitchen ingredient that not only finds its purpose in cooking but cleaning as well. Due to the presence of Acetic Acid, Vinegar is strong enough to kill bacteria and dissolve dirt and grime. For example, to create a concrete grease remover:

  1. Mix half a cup of washing soda, approximately 30 ml ( 2 tsp )of white vinegar, a quarter tablespoon of liquid dishwasher detergent and two cups of water properly in a bucket.
  2. Absorb extra oil from the concrete with the help of sawdust.
  3. Pour the mixture over the stained area and scrub it well with a brush.
  4. Rinse the concrete and repeat till the stain is completely gone.

Cat Litter and Coke

Made up of clay, cat litter is an excellent oil absorbent. However, I prefer the inexpensive options as they tend to do the job better. For this procedure, pour cat litter all over your greased concrete and rub it on the surface by walking all over it. Now, pick a broom, dust off the cat litter and dispose of it properly. Take some Coca-Cola and pour a generous amount on the stained concrete. Scrub it in with the help of a rugged nylon brush. Leave for about twenty minutes but don’t let the surface dry out. Rinse the concrete, and you should then see a grey patch in the place of a grease stain. Take a cup of ammonia-free laundry detergent and chlorine bleach each. Mix in a gallon of hot water and scrub it in the concrete. Rinse and let dry.

Remember, the detergent should be ammonia-free as the reaction between chlorine and ammonia can lead to the formation of lethal gas. In addition, always wear your eye protection goggles and rubber gloves for increased safety.

Trisodium Phosphate

Trisodium Phosphate(TSP) is an inorganic compound that acts as a degreaser and cleaning agent. It can quickly help get rid of old oil stains. It forms an alkaline solution when mixed with water. Mix one cup of TSP into a bucket full of a gallon of water. Then add some sawdust to the bucket till the resulting mixture forms a thick paste with Peanut Butter consistency. Take the resulting poultice and over the stained concrete and let it rest overnight. Check in the morning and brush off the dried remains with a broom. Avoid using this remedy if there are chances of rain overnight.

Oven Cleaner

You can choose any oven cleaner spray available in the market. Just spray it all over the stained concrete area. Let it rest for about ten minutes. Proceed by scrubbing with a hard-bristled brush thoroughly. When done, rinse off with a hose or bucket of water. Repeat the process until desired results have been achieved.

Acetone

Acetone is a strong solvent that can dissolve stubborn stains easily. Mix about two cups of acetone with enough baking soda to result in a thick paste-like consistency. Based on the stained portion you need to cover, you can add or subtract the quantity of acetone used. Spread a layer of the resulting mixture on the stained area and then cover it with a plastic sheet. Tape down the plastic to the concrete and let it rest for about 24 hours. Take the plastic sheet off and let the solution dry. Later, sweep away the dried remains with the help of a brush and rinse off the concrete with a hose.

Conclusion

The beautiful, grey shade of your concrete flooring can be spoiled just because of a grease or oil leak due to the outdoor grill or the parked vehicles. The most preferred choice for patios, driveways or garages, concrete is widely used due to its multiple benefits.

Regular tire tracks and dirt particles can be easily cleaned away with a broom or water, but things get a bit tricky in case of grease stains. Concrete is porous and retains oil particles efficiently. To get rid of oil and grime from such a surface, you need a potent cleaning agent with ample absorbing and scrubbing.
