Driveways are located in the open and susceptible to external pollution, dirt and other debris that may get stuck to the surface of it. Standard ways of cleaning like brushing it with soap water will only get a minor percentage of the dirt separated from its mother layer.

Today, with the help of pressure washers, these powerful water jets can easily scrape off the dirt from the layer with ease. Etching is the process of blasting the concrete with so much pressure that it sheds small bits of concrete giving it a bleached effect from the rest of the layer.

But there are specific tips to be noted before operating such pieces of equipment and focusing them on decimating the dirt from the concrete driveways.

Along with the pressure washers, usually different kinds of nozzles with different shades come attached. Some tips concentrate the pressure in a small and single area, which would lead to etching. Others expand the pressure radius, ideal for cleaning cars and larger objects. The quick tip would be the one suitable for concrete cleaning, which will be specified usually.

House cleaning maintenance pressure washers require anywhere from 3000-3500 PSI. Anything more than this will be too powerful ending up etching everything in the house. Attaching a turbo nozzle would be a good idea, as it rotates the dispersion and does not leave tracks of its work.

If the concrete is scattered with dirt, molds, oil and other stains. It is best to use designated specialized cleaners to get rid of these from its pores and sources. These particular detergents help the dirt and stains afloat from its layer and rise on top. Once the dirt and stains have become loose and fragmented, the coating can be sprayed with a pressure washer to clear of the dirt flooded layer giving it a clean and smooth finish.

Do not try to blast of the sealers or coatings of the cement layer. As it is this layer that gives the cement its protection and defense. Water blasting the layer with too much pressure will crack and break the coating leading to rapid deterioration of the adhesive. In cases where the seals or coating get cracked, remember to apply a new coat as it will strengthen the blocks of cement ability to keep off dirt and stains while allowing easy cleaning of the concrete.
