Concrete cleaning is a process that needs to be regularly maintained in order to attain a beautiful concrete surface always. There are many methods known to men on how to clean a concrete surface. Because of the natural appearance of concrete it is oftentimes hard to tell if it is dirty or not. Dirt in acid stained concrete is even harder to see because of the concretes natural earth tone color.

Dirt, dust and grime are the easiest to clean. They can be cleaned using a mixture of water and household detergent pr soap. Some dirt if to be found in small areas only can be removed through simple scrubbing using scrubbing pads or an old toothbrush. Wide areas that need to be cleaned should use a power washer instead. Power washing uses pressurized water coming out of a nozzle.

Grease and oil stains in concrete can be cleaned by pouring hot water with a mixture of household detergent or soap. Hot water lifts off the grease from the concrete. An alkali degreaser is then added to it since it emulsifies the grease and oil thus making it possible to wash out with the power washer. Some floor cleaning contractors use alkali degreaser also when cleaning simple dust and dirt off concrete since they are sometimes are oily too.

Paints are the hardest to remove since they tend to adhere more to the concrete surface. A potassium hydroxide cleaning agent should be used to remove paint stains. However, this type of cleaning agent tends to be too aggressive. A citrus-based solvent can be used instead which is less aggressive. A potassium hydroxide cleaning agent should be allowed to settle for a few hours before power washing.

Paints can also be removed through the use of tungsten-carbide nozzle power washer with sand and water stream coming out of it. This type though can lead to concrete damage because of the sand bits and pressurized water. A softer sodium bicarbonate adhesive in power washer can be used instead.
