How to Clean Grease off Concrete

There are tough surfaces to clean. Kitchen surfaces are easier to clean as they are inside, painted, and may have a sealant on the walls or floors protecting them. But if you go to your outdoor barbecue and look at the concrete around it, you will find a very tough surface to clean.

Concrete is a tough surface to remove grease, but it can be done. It may take some stronger cleaners than you use inside but with a little effort, it will get clean again. The good thing is you do not have to worry about scratching concrete.

To learn how to handle this task, just continue reading our article. It has solutions you can use anytime.

How to Clean Grease off Concrete

1. Commercial Cleaners

These chemical-based products are tough, powerful, and can handle removing grease from concrete. The two main things you need to remember are to remove all items away from the grease stain. This protects them from splashes.

The second is to not do your cleaning when the temperatures are below 50 degrees F. The warmer the temperature, the easier it is to remove the grease. A third main thing would be to follow all instructions on the package. But here are some general guidelines to use:

  • Dilute the commercial cleaner to 1 part cleaner to 4 parts water
  • Apply the solution to the grease stain and let it sit for about 3 minutes or so
  • Do a second application when those few minutes have passed and then scrub the area
  • Use a good scrub brush to remove the grease. No need to go with soft bristles here.
  • Continue to scrub and add the solution until the grease stain is gone
  • When you are finished scrubbing, you need to rinse the area thoroughly then let dry

2. Baking Soda and Water Paste

It is a simple solution to mix together, and you want the paste to be runny but not too runny. The paste should be about the same as pancake batter. Once that is ready, clean the surface with clean water to get rid of any dirt.

Next, apply a generous amount of the paste and cover the stain completely. Do not do anything except cover the stain. When that is done, cover the paste with plastic and secure the plastic in place.

Leave the paste covered overnight and, in the morning, remove the plastic. When the plastic is removed, take a plastic scraper, and scrape off the paste. Throw the pieces into the trash and then rinse the area thoroughly.

3. Baking Soda Alone

In this method, you are going to use dry baking soda and sprinkle it over the grease stain. You can be liberal here, but make sure you cover the stain completely and let sit for 30 minutes.

While you are waiting, mix up some dishwashing liquid and warm water. The amounts you use will be up to you, just make sure to get a lot of suds. Then using a nylon brush, dip the brush into the solution and start scrubbing.

Use a circular motion when scrubbing and keep doing this until the stain is gone. Once it is, rinse well and let dry.

4. Trisodium Phosphate & Water

This is pulling out the big gun when it comes to fighting grease on concrete. But when the grease stains are old and have set in, you need a very powerful cleaner to get that grease out. Trisodium phosphate is that powerful cleaner.

All you need to do is mix 1 cup of TSP with a gallon of water in a large enough bucket. Then add some sawdust to help create a paste. Go slowly when adding this ingredient as you do not want to add too much.

When this solution is ready, spread it over the grease stain or stains and let sit overnight. Then like the baking soda paste, scrape the paste off in the morning. Throw away the paste pieces before rinsing the area.

Some Grease Stain-Fighting Tips

1. Stop the grease before it becomes a problem. If you do a lot of cooking outside, have a supply of sawdust on hand. When you see grease hitting your concrete, spread the sawdust over it to prevent it from soaking in. Or just have a towel handy and wipe it up right away.

2. Muriatic acid is a good grease stain remover. This is your last gasp cleaner to use as it is very powerful stuff. Just be careful when using this option as muriatic acid is dangerous to your health and skin.

3. Acetone is another fine grease remover for concrete. It works even better when you mix it with baking soda and turn it into a paste.
