Brick is a porous material and can be badly damaged when exposed to high-pressure water. Rather than rely on water pressure, soft washing will use detergent to effectively remove stains and buildup from brick surfaces. Apply the cleaning solution for 5 to 10 minutes, then rinse off using 500-1,000 PSI.
The granules on top of roof shingles serve as a protective layer against UV rays and other natural elements. Pressure washing can damage this layer and weaken the structural integrity of the roof. In addition, water can go in between shingles which can encourage the growth of mold, mildew, and algae. Soft washing can effectively clean roof shingles without causing significant damage. Use effective cleaning solutions and stick to 500 to 1,000 PSI.
Soft washing is a gentle cleaning method that’s ideal for delicate glass surfaces. It can remove all the dirt, dust, and grime without causing any breakage or damage. The use of cleaning solutions also helps give glass surfaces a squeaky clean appearance.
Wood is a popular material for panels, decks, and other exterior surfaces. Over time, it can develop black and green stains, as well as mold, mildew, and algae. Pressure washing is not ideal because it can leave wood surfaces damp, thus making it conducive to microorganism overgrowths. The best way to clean wood surfaces is by combining low-pressure water and potent cleaning & disinfecting solutions.
Stucco surfaces, particularly those made from acrylic resin, can be damaged by high-pressure water. Soft washing provides the same level of clean as pressure washing — but without risking the quality of the stucco surfaces. Apply a cleaning solution for 5 to 10 minutes. After the stains and buildup have been dislodged, use low-pressure water to rinse the stucco surfaces.
Surfaces with Mold, Mildew, and Algae
When dealing with mold, mildew, algae, and other hazardous materials, high-pressure water is often not enough. In some cases, pressure washing may remove these microorganisms but only for them to come back with a vengeance. To really remove mold, mildew, and algae, you need to use chemicals that will kill the microorganisms and prevent them from coming back. This can be easily accomplished through soft washing.
