What’s the best pressure to clean your home, building or concrete driveway?
Many home owners, apartment complexes, and commercial businesses are looking for a safe way to have their exterior siding cleaned. Most of them assume that high pressure washing will achieve the best results, but they’d be incorrect. Read on to find out why low pressure washing is usually better than high pressure cleaning.
When to use Low Pressure, also known as Soft Washing
The best way to clean the exterior siding which can be wood, metal, vinyl, stucco, eifs, hardiplank, stone or brick is using low pressure. It is often misunderstood that high pressure should be used to remove a tough stain such as: heavy mold/mildew, rust, or red clay. High pressure will cause the siding to suffer serious damage such as splitting or parts breaking off. The use of environmentally friendly chemicals applied with a low pressure tip is best, easiest, and the safest way to clean exterior siding.
When to use High Pressure
The use of high pressure is only needed to clean porous surfaces such as your concrete sidewalk, patio, porch or driveway. These surfaces can sometimes be cleaned with chemicals alone, but it is very expensive. The most economical way to clean these concrete surfaces is with the use of a commercial grade surface cleaner. We use commercial grade surface cleaners for all our concrete cleaning needs. A picture of the type of surface cleaner we use is shown below. Sometimes mold/mildew will not be removed with just pressure alone in which case we lay down a diluted sodium hypochlorite mixture to kill any remaining mold spores.
