The Secrets of Concrete Cleaning
Concrete is no longer limited to outdoor use. The strength and durability of concrete have always made it the perfect surface for roads, sidewalks, and driveways, but those characteristics also prove useful inside the home. Concrete is now regularly used for indoor flooring and in some cases countertops.
Homeowners with indoor concrete surfaces frequently ask how to properly care for it. Sure, you can power-wash a driveway or garage floor, but how do you care for indoor concrete finishes?
Here’s how to give your concrete surfaces the attention and care they deserve:
Indoor Concrete Stain Removal
Indoor concrete surfaces typically require less maintenance than outdoor concrete because the surface of indoor cement is usually sealed. Stain removal for indoor concrete is needed less frequently since sealed surfaces are nonporous and therefore more resistant to staining.
The best way to keep your indoor concrete clean is to regularly dust, vacuum, and mop. This will help prevent any lasting damage from dirt or grit. You also have to be careful about what products you use to clean your sealed concrete. Harsh cleaners can break down the sealant or paint, which could lead to lasting stains.
Outdoor Concrete Stain Removal
Cleaning outdoor cement surfaces can be trickier because the stains often sit for longer periods of time and set in before they are cleaned. This is what makes outdoor concrete stain removal so difficult, often requiring the equipment and training of an expert COIT technician.
If you do attempt cleaning outdoor concrete yourself, the first step to removing any stain is to clean debris or dirt off of the surface. Once the surface is clean, you can then determine how to best clean the remainder of the stain.
A Cool Trick for Removing Rust Stains
Patio furniture, garden tools, and other metal objects will leave rust stains on a concrete patio or driveway. Here’s one cool trick to remove those ugly rust stains: Mix unsweetened Kool-Aid lemonade with hot water, then scrub and rinse. You can also use vinegar instead, soak for a few hours, then rinse.
Getting Rid of Oil/Grease Stains
If there is an oil or grease stain, you’ll have to treat the area carefully. Cleaning oil from cement is much more difficult than it is to remove oil from carpet.
The main reason it can be difficult to remove old oil stains from concrete is because the surface is porous, but it can be done. The stains will need to be brought back to the surface in order to remove them.
How to Remove Motor Oil from Driveways
Motor oil from cars is a common stain found in most driveways. To remove the motor oil, cover the area with kitty litter or corn starch and grind it in with your feet while wearing old shoes. Sweep up and rinse the area and repeat as many times as necessary. If this does not work, you can try spraying a generous amount of WD-40 or oven normal cleaner on the stain. Let the substance sit for 5-10 minutes and use a high-pressure hose to rinse it off.
For older grease stains, you might want to consult a professional cement cleaner like COIT.
Remove BBQ Grease
To remove BBQ grease from your masonry, make a paste of powdered laundry detergent and water. Cover the stain with 1/4 inch of your paste mixture and securely tape plastic wrap on top. Leave for 24 hours, scrub, and rinse away.
Stains from Leaves & Potted Plants
Scrub a mixture of dish soap and water onto the stain and rinse it off using the high pressure setting on a garden hose with a nozzle. You can also use hydrogen peroxide-based cleaners instead of dish soap. Let it sit on the wet stain for about 10 minutes or so, then scrub in a circular motion until the stain is removed.
How to Remove Tire Marks
If you need to remove tire marks from your concrete, spray the area with a hose and then wipe with a degreaser. Leave the solution for several hours, and scrub it with a stiff brush to remove the stains. Rinse well and repeat if necessary.
FOR THE MOST STUBBORN CONCRETE STAINS, COIT CONCRETE CLEANING CAN HELP
In some cases, over-the-counter cement cleaners can make a difference in removing stains from concrete, but this is definitely not a guarantee. The main reason concrete stains are so stubborn is due to how it can be difficult to bring set-in stains to the surface.
Our Concrete Floor Care aggressively attacks tough stains by removing stains that are trapped deep within concrete floors. If normal cleaning and maintenance is not effective, we can help you handle the tougher stains.
