Best House Cleaning Service Method
Deciding to have your house siding cleaned is a big step for improving the appearance of your home, and there are often misconceptions on what a house wash service entails. Unlike plumbing or heating and cooling, having your house or roof cleaned is primarily to increase curb appeal.
Two Primary Pressure Washing Methods
There are two ways that a surface can be cleaned by pressure washing. The first method is high-pressure washing, also known as “power washing.” This is commonly used on concrete and other hard surfaces to remove dirt, grease, gum, and oil. Until recent years, this was the primary way to clean any surface, including roofs and siding.
Low-pressure washing, commonly referred to as “soft washing,” is a method that uses low pressure in conjunction with a cleaning solution to gently wash the surface. Various soaps and cleaning solutions are used in lieu of high pressure, making for a less volatile method of cleaning.
Soft washing versus Power Washing
The difference between soft washing and power washing may seem obvious, but some might assume that the difference is negligible since the outcome is the same: the removal of dirt, mold, and mildew. It’s true, the end result appears to be the same, but looks are deceptive.
In the midwest, mold and mildew are the most common growths on vinyl and stucco siding. They are spore-based parasites, spreading through the air and landing on various surfaces. They tend to prefer moisture and shade. When traditional power washing is used on a house, the spores are blasted into the air, settle, and begin to regrow. It isn’t uncommon for houses that have been power washed to have mold and mildew growing again within a matter of days or weeks.
Soft washing uses a mild chlorinated solution, around 1%, to kill the mold and mildew. This, coupled with low pressure water, essentially treats the siding and helps prevent regrowth by eradicating the problem. The solution is mild enough to not harm plants and animals, but strong enough to get rid of mold and mildew on siding.
Power washing also presents a risk to vinyl and stucco, as pounds per square inch (PSI) can be in the 3,000 to 5,000 range, high enough to put holes in your siding. Power washing also requires every square inch of the siding to be cleaned using a narrow stream. It is time consuming and expends a high volume of water.</p> <p>Soft washing uses much lower pressure, less than 1,000 PSI, and can be applied in a cone or fan, covering more area faster. This uses less water and takes far less time than traditional power washing. Add in the substantially reduced risk of damage to siding, soft washing is the clear choice when looking for a professional exterior house cleaning service.
