Why Do Pressure Washers Work So Well For Retail?
Updated: 3 days ago
Pressure washing is the best way to clean your building’s exterior and surrounding area. Here’s why:
Ever wonder how pressure washers manage to get everything so clean? Again and again pressure washing manages to get your building looking good as new despite built up grime and grease. Well, here is the science behind this wonderful cleaning method.
A pressure washer is essential an engine that powers a highly pressurized water pump. The motor helps pull water in so that it can be pushed out through the hose. The water inlet is the hose that connects a water source to the machine. The water is then expelled through the high pressure hose. This is typically a long skinny piece that forces the water out at a rate of about 2000 to 3300 pounds per square inch, or PSI. It is this pressure that helps get rid of the tough stains and dirt that can’t be removed by elbow grease alone.
Sometimes a pressure washer by itself isn\’t enough to get the job done. That’s why professionals use cleaning attachments and detergents to ensure your building will look spotless. Attachments include rotary nozzles that increase the surface area of the spray and rotating brushes to clean the more stubborn stains. For a particularly deep clean in a fraction of the time, pressure washers use hot water and detergent much like a dishwasher. Depending on the surface, a hot water and detergent mixture is sprayed over the entire surface to help break up the dirt, mildew, and grease. Then a cold water rinse washes it all away.
Regularly scheduled pressure washing can keep any building exterior clean whether it’s brick, concrete, stucco, or anything else. Our professionals will use the proper tools and techniques to tackle your project.
Not every surface can handle the same pressure, which is part of why hiring a professional matters. Brick and concrete can typically handle higher PSI without issue, but softer materials like painted stucco, wood trim, or window seals can be damaged by too much force. A soft-wash approach, using lower pressure combined with the right detergent and dwell time, gets the same clean result on delicate surfaces without stripping paint or driving water behind the exterior finish.
How often a retail storefront needs pressure washing depends heavily on foot traffic and exposure. A location on a busy sidewalk with heavy pedestrian traffic, nearby food vendors, or a loading dock will accumulate grime far faster than a low-traffic suburban strip mall. Most of our retail clients land on a quarterly schedule for entrances and walkways, with more frequent spot cleaning for high-visibility areas like the storefront glass and main entry.
There's also a regulatory side to pressure washing that's easy to overlook. Wastewater from cleaning a parking lot or loading area can carry oil, grease, and detergent residue that isn't allowed to run directly into storm drains under local and EPA regulations. Professional crews use containment mats, vacuum recovery, or approved discharge points to keep runoff out of the storm system, which protects your business from potential fines if an inspector traces contaminated runoff back to your property.
