I’m sure you’ve heard of pressure washing by now. If you didn’t, you wouldn’t be reading this article. Sounds cool… but how to pressure washers work? If you’re anything like me, it’s not enough to just be amazed by the results. You want to know if the results that you see are the true results and how it works. After all, just because something looks clean, that doesn’t mean it is!
If you’ve ever had power washing done, you’ve no doubt heard of the different terms in the industry, too. Power washing, pressure washing, soft washing. I’m sure you’ve even heard NOT to power wash. So how can you tell what to do?
I’m going to address in this article how pressure washing works and how we make it work for you and whatever surface you need cleaned!
Why Pressure Jets Get Things Cleaner
There’s a good reason why water gets things so clean. Ever try to clean something without it? It’s much harder, isn’t it? Water’s molecules have an electrical (not much) polarity so they tend to stick to things that they come in contact with. When it sticks to things, like dirt and grime, it tends to wash it away from whatever surface it’s on. When you add detergent to the mix, it helps water do its job by breaking down dirt, grime, and grease and makes it easier to wash away.
But sometimes the ground in dirt does not come off with just water alone. That’s when a pressure washer comes in. A pressure washer uses a high pressure jet of hot or cold water to blast dirt free. The water travels fast, hits the surface with a higher energy, and knocks the dirt and grime away with force.
If you’re doing this process yourself, it’s best to try it out on a small hidden part of whatever surface you’re cleaning before you go to town on the main areas. If you see that it’s damaging, try using a wider nozzle so that the pressure isn’t so high.
Components of a Pressure Washer
It may seem complicated but it’s really not. All a pressure washer is, is a water pump that is powered by a motor. You can use ordinary water from the house in the washer. The pump accelerates the water to a high pressure and then sends it through the hose at a high speed. The nozzle that is used helps determine what pressure the water is that is coming out of the hose.
Water Inlet: This is the hose that connects the pressure washer to the main water supply. Usually there is a filter in there that keeps solid objects from being processed through the washer and blasting out of the other end.
Electric Motor or gas engine: This is what powers the pressure washer. There are two different kinds. Most smaller pressure washers run off of electricity that is pulled from the home or building that’s being washed. The larger models tend to use gasoline engines. Gas engines are also beneficial if you’re working outside in a place where electricity is hard to find like at a park or other outdoor area that needs cleaning.
Water pump: This is what sends the water from the water source out of the hose and to the surface. Without the water pump, nothing would happen. Pumps are designed to handle a water flow of around 1-2 gallons per minute.
High Pressure Hose: This is what the water travels through to get to the surface from the pump. High pressure hose is reinforced with wire mesh and has a few layers of high-density plastic. It’s important to use a hose that has a higher pressure rating than an ordinary hose.
Cleaning attachment: This changes depending on what you’re cleaning. You wouldn’t use the same attachment to clean a roof as you would use to clean a driveway. This is one of the things that controls the pressure that comes out.
