A Guide To Buying the Best Gas Pressure Washer

Tips to get perfect results using a gas pressure washer

How you use the pressure washer makes a lot of difference. Technique matters a lot. Every target is different, and every stain demands a separate technique for perfect cleaning. Here are some examples. 

Outdoor cleaning

If you are cleaning around the house, the driveway is the one place that requires most of your attention. This place is home for many tough stains like Track marks, dirt, fallen leaves, pine cones, grass leftovers after mowing, etc. The good news is that all these things can be cleared out in just one wash. You do not require t use high pressure for lightweight tasks like cleaning the fallen leaves or pine cones. Just one small bow is enough to clear out the way. On the other hand, tough stains like Track marks, dirt, oil spills, and grease require high pressure. You might even need spot cleaning nozzle for this purpose.

Patios and furniture

Having a patio in your house can feel like heaven, but we all can agree that they are home to most of the moss. For cleaning it, you will require heavy water pressure and a tighter nozzle. It might take a lot of time as per the spray range is less, but you will get a perfectly clean patio in just one wash.  

The pressure washer is perfect for cleaning out furniture as well. So not confuse it with your lounge furniture; we are specifically talking about garden furniture only. Garden furniture is designed to withstand the rain, due to which you can easily pressure wash it. You can use it to wash plastic furniture as well, but be careful while using a high-pressure nozzle on low quality plastic. It can damage it.

Cars and decks

These are the most common uses of pressure washers. Cars are the first thing anyone cleans after getting a pressure washer. You will get a shiny car in a few minutes. Just be very careful while selecting the nozzle and soap. If you use excessive pressure, it will damage the exterior and rip off the paint. Soap should have diluted chemicals as well. If you are using a strong chemical, the paint will start to fade. You can use the high pressure of car mats.

For cleaning out the decks, it is recommended to use high pressure. Mostly the surface of decks is strong and solid. While cleaning the deck, make sure that you get the creasing between the boards. 

Frequently Asked Questions on Gas Pressure Washers

How to Start a Gas Pressure Washer?
Even if you are using a gas pressure washer for the first time, there is no need to worry. These are simple to set up and get started. Most people get startled by the heavy appearance and by the fact that these are actually used for industrial purposes. 

The first and most important step is to get started in the right way. Keep the pressure washer on a clean, dry surface. The most basic step is to connect the water inlet with the water supply. This should not be a problem; you just have to connect one end of a water hose with the water inlet and the other one with a water source. Now connect the high-pressure hose with the outlet of your unit. Connect the spray gun to the other end. Make sure that you tighten each connection in order to avoid any leaks. Select the most suitable easy to connect nozzle and attach it to the spray gun. Now, you are all set to get started. The connections are simple, and you will not feel any problem up to this point. 

Open the water source. Press the trigger and open the fuel valve. Now, it’s time to open the choke. You simply have to turn it to the left. Open the throttle in the same way by moving it to the left. Up till now, all the steps were pretty simple, and even if you make any mistakes, there is no problem. But after all these steps, the real part begins, and you need to be extra careful. Start the engine and press the trigger gun. You are all set to start cleaning. 

Electric or gas pressure washer, which one to prefer?
Both provide perfect cleaning; what really matters is your preference. Whether you want to save water or fuel. If you are looking for an environmentally friendly option, an electric pressure washer is a right option for you. But keep in mind, no matter how strong electric pressure washer is, it will not be able to provide ultimate power like a gas pressure washer. 

Gas pressure washers are extremely powerful, which is why they are mostly used for commercial use only. These can be heavy, but easy to move around and keep. The most amazing thing is that you are not restricted while using these units. You do not have to be near any electric socket. You can take the unit wherever you want and just start it. All these units have one major problem; that is, there are loud. You won’t be able to work without disturbing your neighbors, and there might be times when you need to cover your ears. As per these units have heavy motor, these are not very stable. They tend to vibrate and might tip over if you have been working for hours. 

Electric pressure washers are well suited for lightweight tasks. These units are easy to handle. These are perfect for residential use. The best part is that these units are extremely portable, and keeping them won’t be a problem. The only problem you are going to face is the chords. You have to connect it to a socket in order to get started. This limits your certain area. Even though the electric cord is long enough to reach distant areas, but there might still be times when it is not enough, and you have to unplug it and look for other nearby sources. 

What types of gas used in gas pressure washers?
Most of the users get confused over the type of gas used in gas pressure washers. There is no specific type, to be honest. Most of the high-end pressure washers are well suited for multiple types of gas. Before you get started, it is important to check the guidelines and stick by it. Like another gas-powered machine, the performance of these is also dependent on the type of gas you are choosing. It is better to choose the one which has higher octane content. Anything with at least 87 octanes should be fine. Make sure that whatever gas you are choosing it is clean and fresh as per the whole performance, and water pressure depends on it.
What is a good PSI and GPM for a pressure washer?
Before getting any pressure washer, learning about these two terms is extremely important. I have seen people not considering PSI important and ignoring the fact that the whole performance depends on it. First, understand the difference, and then we will move further. PSI is the force or pressure that knocks the dirt/moss/mildew loose from the surface, whereas GPM is what carries those particles away.

Any PSI and GPM can be good for you; what really matters is the target you are facing and what type of cleaning you are looking forward to. According to my observation, 2,500 PSI is a good pressure for performing most of the jobs. If you are looking forward to professional cleaning, it is better to look for higher pressure. 


If you are one of those people who like everything perfectly clean, get yourself a pressure washer today. These wonderful machines are able to do wonders. You can clean almost anything in a matter of a few minutes. Having a powerful gas pressure washer lying in your garage can half of your tensions away. You will no longer have to look for professional pressure washing services. All the above-mentioned gas pressure washers are the strongest units available in the markets. Most of these are perfect for both residential and commercial use. We have covered every feature by each of them, select the one which suits the most to your cleaning requirements.
