When is High-Pressure Power Washing Necessary?
As discussed in our "Soft Washing vs. Power Washing” article, due to it’s efficiency, low-risk, and long lasting results, soft-washing is the preffered method of exterior cleaning by professionals and consumers alike. So when is it necessary to turn up the pressure or heat?
Some substances are naturally more porous than others. Concrete, stone, clay, and brick are just a few that tend to be very absorbent. This means they are more vulnerable to soaking up water, air, dirt and grime. Left unkempt, these surfaces not only compact layers of gunk, but also become breeding grounds for mold, mildew, and algae. Without a regular cleaning the contamination will soak deep into the layers of some materials.
Fortunately, the porous characteristic of these materials also lends itself a great deal of resilience when applying high levels of water pressure and heat. Without using water pressure, it is nearly impossible to reach some of the deeper stains in concrete, stone, clay or brick. For the dirtiest of surfaces, water pressure alone is not enough to uproot the filth. Adding heat, provides the additional cleaning strength necessary to remove some of the toughest slime, stains and growths.
Luckily, these porous materials can handle the added pressure and heat. But don’t try these methods on the more fragile surfaces. Never apply pressure to your siding, wood deck, fence, or otherwise! Always consult the professionals first. At Wash Pro, we’re more than happy to provide feedback concerning any of your exterior cleaning needs.
