Pressure washing professionals understand what it takes to get the job done, and sometimes that requires the use of different techniques that can vary depending on the project. Without the knowledge or experience of using pressure washing techniques, it’s easy for DIY-er’s to damage surfaces, injure themselves, or pressure wash ineffectively. We’ve asked professionals for the best tips they could come up with, and we’ve compiled the list of their answers for you here.
1. Low-pressure Washing
The whole purpose of power washing is to blast away grime with a high-pressure stream of water, but too much pressure can cause significant damage to whatever you’re washing. Power washing with too much pressure can permanently damage a wood deck, for example. It’s important to know when you’re using too much pressure, and what kinds of pressure the surfaces you are cleaning require. Low-pressure washing techniques provide an alternative method of cleaning that is easier on easily damaged surfaces. Low pressure washing can also be combined with chemical agents to produce more satisfactory results.
2. Cleaning Agents
While most homeowners consider the water jet from a pressure washer to be sufficient for thorough cleaning, a skilled professional power washing service will employ the use of cleaning agents to maximize its cleaning potential. Cleaning agents help lessen the power washer’s workload so not as much pressure is required to do the job. A quality company will even use its own proprietary, biodegradable cleaners to help wash away mold, mildew, and dirt without harming the environment.
3. Hot Water Pressure Washing
Hot water can clean much more effectively than cold water, and professional pressure washing equipment is often modified to include a burner that heats the water up to 99 degrees Celsius. A professional will also know when NOT to use water that’s too hot – such as on vinyl siding, which can warp.
4. Different Nozzles
Using different nozzles can also make a power washing professional more productive. A turbo or rotary nozzle, for example, can be more effective at cleaning some surfaces than the typical fan-shaped nozzle. Another useful tool is a surface cleaner, which appears similar to a floor buffer and saves time and energy by cleaning a wider area with each pass. Nozzles come in the following options: Rotary nozzles, Brass soap nozzles, Sewer nozzles, Duct cleaning nozzles, Foam nozzles, and Steam nozzles.
