It usually takes 1-2 hours to pressure clean a driveway and it's the most effective solution for cleaning hard surfaces like concrete, asphalt, pavers and tiles.

While pressure cleaning is an effective method for outdoor cleaning, its application inside a house is fraught with risks and is generally not advisable. For indoor cleaning, safer and more suitable methods such as steam cleaning or professional services are recommended.

As opposed to scrubbing an exterior surface by hand, power (or pressure) washing is a faster, more effective way to clean. Cleansers treat the surface for the typical contaminants like dirt, grime, algae, mold, and mildew. Afterward, a safe yet appropriate amount of pressure is used to rinse everything away.

For even cleaning, use a grid pattern: Start at the top of the project and move side to side. A wider spray equals faster cleaning, while a tighter spray equals deeper cleaning. Tip: Hold the nozzle tip about four inches away from the area you are cleaning. Move closer for harder to reach stains.
