How to winterize a gas pressure washer

When it comes to pressure washers, there are countless options that people can choose. From the vast variety that comes with choosing electric pressure washers, you are also able to leisurely choose gas or a battery-powered one. Each of them come with their own functionality, and they offer excellent use.

Whether you are using it around your house to clean some stubborn algae and mold, or you are planning to use it in an industrial site, the point is, you need to ensure that the pressure washer that you have is one of the best ones. So, how do you choose a pressure washer? The simple answer is through research.

With the help of the internet, you can pick and choose the different types of pressure washers that are available, as well as the different pressures that they might come with. You are also able to choose the settings, or fully customize your own pressure washer.

However, the main issue does not lie in the seasons where you are using the power washer, rather the main issue arises when you are done using the pressure washer for the season and need to winterize it. This article will cover how to winterize your gas pressure washer in a safe and effective way so let’s get started!

Winterizing your pressure washer

The first step that you will need to take is that if you are not planning to use your power washer for the long-term future, then you need to store it in a safe way. In order to do that, the first thing that you need to do is to remove the soap and water that is present in the pump system of your gas pressure washer.

The next thing that you will need is a fuel stabilizer, which you can add into the gas tank, and start the engine for a total of 2 minutes. The fuel stabilizer will run throughout the entire system, and it will distribute the stabilizer into the pump system.

Moving on, the next step that you need to take is to remove any water that might still be present in the power washer’s water system, and while you are it, you might want to also check if there is any remaining cleaning solution, as it can go bad if left alone for the entire winter season.

Once you are done with that, the next step that you need to do is to connect your gas pressure washer to your garden hose, and using a clean water supply, turn on the pressure washer’s system, and let it run on low pressure for a few minutes. What this does is that it allows the excess detergent that might still be left behind to empty out of the system.

Lastly, using an “Anti-Freeze” pump saver, add that to the pump system, to ensure that it will not freeze over if the temperatures end up dropping too low.


So, these are some of the ways that you can winterize your gas pressure washer and ensure that it will never get ruined.
