Mix a solution of 1/8 of a cup liquid dishwashing detergent, ½ cup baking soda, and one gallon of water. Pour over the stain. Use a soft brush to scrub the stain away. Rinse the area.
Dish soap and water: Dish soap is a degreaser, and it works well to clean oily and grimy concrete. Create a cleaning solution of warm water and few drops of dish soap and apply it to the surface. Let it sit for a while, then mop the patio and rinse it with fresh water. Repeat the process as many times as needed.
Trisodium phosphate (TSP) mixed with water and scrubbed onto the stained area with a nylon bristle brush can remove tough stains. Scrub until the stain is gone and rinse with a hose. TSP is available at home improvement stores.
Vinegar and Baking Soda
Cleaning concrete with vinegar or baking soda is a good option if you are looking for a natural cleaner. While cleaning concrete with bleach or detergent can be effective, it can also be toxic to plants.
A quick answer is yes! White vinegar can clean concrete and remove stains. It may not be as powerful as concrete cleaners, but it can clean up concrete stains on a budget. Not to mention that vinegar can also remove germs and bacteria from concrete.
Cleaning concrete with vinegar will not damage it! However, saturating concrete for an extended period will damage the cement that binds concrete together. Over time, vinegar erodes the concrete itself, so be careful.
What chemical will clean concrete? If you have mildew stains, the best chemical to clean concrete is trisodium phosphate. Combine two tablespoons of the chemical with two tablespoons of powdered laundry detergent and one-quart water. Then, apply it to the stained area and scrub using a stiff brush.
Most stains on concrete floors can be removed quickly and easily, but a lot depends on how old the stain is and how porous the concrete surface is. Rust, oil, grease, paint or glue stains each have a recommended stain removal technique.
There are two types of concrete stain to choose from: acid-based and water-based. Acid-based formulas for are long-lasting and resistant to fading. They react chemically with the concrete to create a permanent chemical bond. This means it will not peel or chip and will help produce a natural-looking finish.
Acid Staining
Acid stains are a reactive coloring process that penetrates into the porous concrete surface. This is probably the most permanent of all coloring options but is usually limited to eight colors.
Spray a mixture of hot water and oxygen bleach onto the concrete. Follow the mixing instructions on the oxygen bleach for best results. The oxygen bleach helps whiten the concrete and is not as toxic as chlorine bleach.
Baking Soda
Salt and commercial ice-melt formulations can stain — or actually eat away — the concrete around your house.
However, if you don't notice any damage to the floor, it's possible that you can restore shine simply by cleaning with a microfiber mop and a concrete floor polishing agent which can break down surface dirt and grime. To clean concrete floors, stat with small areas to ensure there is no dirt or grime left behind.
Whether your patio is sealed concrete or cement, or even sealed concrete pavers, a bleach and water solution makes it easy to clean away built up soil, stains from leaves and pollen, mold, mildew and algae.
As long as it is properly sealed, concrete is non-porous, making it resistant to stains and exceptionally easy to clean and maintain. Stained concrete floors should always be protected with a good floor sealer to help it resist water, dirt and stains.
In other words, water-based stains perform by flowing into the concrete pores and bonding with the cement, but they do not chemically alter the concrete itself. This means that by definition they are not permanent — if you don't apply a sealer, they can wear away.
Mix bleach with water and then add dishwashing detergent to the mix and put it into a spray bottle. Spray the solution onto the cement patio, let it sit for a few minutes, then scrub the mix into the concrete with a stiff brush.
The answer is yes, salt does indirectly damage your concrete driveways, patios and sidewalks. Bumps and potholes don't just appear due to regular wear and tear – salt damages concrete over time by causing corrosion to occur under the surface, leading to discolored, cracked and crumbling concrete.
Vinegar does not dissolve concrete itself but can degrade the cement that binds concrete together. As a weak, dilute acid, vinegar will cause only minor damage to concrete but can take the shine off polished surfaces. It can, however, be used to remove small amounts of cement from tools.
Usually this white or off-white discoloration to concrete and masonry forms when soluble salts and other water dispersible materials come to the surface through capillary voids as a result of temperature changes, moist migration, condensation, rain, dew, and/or too much water in the mix.
This White Concrete Stain is a water-based stain that offers a decorative natural appearance for concrete floors, brick, plaster, and natural stone. White Concrete Stain Features: Low Odor. Low VOC.
Concrete, by nature, is a porous material. In fact, if you examine concrete under a microscope its appearance closely resembles the appearance of a kitchen sponge. For this reason, untreated concrete surfaces are prone to staining.
