Pressure washing, also known as power washing, is a highly effective method for cleaning surfaces such as sidewalks, driveways, buildings, and yes, even dumpsters. But what exactly is the science behind pressure washing, and how does it work to remove stubborn grime and harmful bacteria? Today, we at All Out Pressure Washing would like to look into the intricate mechanisms that make pressure washing such a powerful cleaning tool.
How Does a Pressure Washer Work?
At its core, pressure washing harnesses the power of water, nature’s universal solvent, to dislodge and wash away dirt, grime, mold, mildew, and other contaminants from surfaces. However, it’s not just the force of water alone that achieves these results; it’s the combination of water pressure, flow rate, and sometimes added cleaning agents that make pressure washing so effective.
Exterior Cleaning Power
Water pressure is the primary driver behind pressure washing’s cleaning power. Pressure washers are equipped with powerful pumps that increase the water pressure significantly beyond that of a regular garden hose. This high-pressure stream of water can range from 750 to 30,000 pounds per square inch (PSI), depending on the equipment used and the surface being cleaned.
Breakdown of Filth & Grime
The high pressure generated by the pressure washer creates a forceful stream of water that effectively breaks the bond between the surface and the dirt or grime adhering to it. This force is crucial for dislodging stubborn contaminants that may be deeply embedded in porous surfaces like concrete or brick. Also, the flow rate of water expelled from the pressure washer nozzle also plays a vital role in cleaning efficiency. A higher flow rate means more water is delivered per unit of time, which helps to flush away loosened debris and ensure thorough cleaning.
Temperature of Water Can Enhance Cleaning
In addition to water pressure and flow rate, the temperature of the water can further enhance the cleaning process. Hot water pressure washers utilize heated water to dissolve grease, oil, and other substances more effectively than cold water alone. The heat helps to break down molecular bonds, making it easier to remove tough stains and sanitize surfaces.
Specialized Detergents
Some pressure washing applications may require the use of specialized cleaning agents or detergents to target specific types of contaminants. These cleaning solutions are often applied using the pressure washer’s built-in detergent injection system, which mixes the cleaning agent with the pressurized water stream before it exits the nozzle. The combined action of the cleaning solution and high-pressure water enhances the removal of dirt, grime, and bacteria, leaving surfaces clean and sanitized.
Effectiveness with Removing Bacteria
When it comes to removing bacteria and other microorganisms, the mechanical action of pressure washing combined with the use of hot water and appropriate cleaning agents is highly effective. The forceful stream of water physically dislodges and washes away bacteria from the surface, while heat and detergents help to kill and remove any remaining microbes, leaving the area clean and hygienic.
