Steps To Winterize Pressure Washer

So, how to winterize pressure washer? Prepare for the following steps below that it only takes a few minutes to complete each of them: 


Step #1. Getting the user’s manual ready

Get the user’s manual ready to winterize the pressure washer. Know that each is a unique model to find with special requirements. Winterize the pressure washer after you clearly understand the instructions in the user manual.


Step #2. Using fuel stabilizer

Use a fuel stabilizer as recommended in a gas-enabled washer to safeguard the engine. Things can occur with gasoline when left during the winter months. Firstly, it turns out less-flammable after it reacts with the oxygen as this decreases flammability, so it’s challenging to start the engine. The engine then sputters and operates roughly. Compare it with fresh gas, and you’ll see it’s old already. It is terrible if you know the gas is darker.

Secondly, gasoline hydrocarbons create gum after it reacts with oxygen. The gum stays with each surface of the fuel line, causing engine failure and premature water over time. That’s when a fuel stabilizer helps solve the issues. It does keep the gasoline as fresh as possible and more extended. Gum particles do not form in this case. The stabilizer also removes any gunk that has already been developed. Choose products like Sta-Bil, Star Tron, & many more that work. Then, place the fuel stabilizer on the gasoline. Allow the engine to operate for 2 or 3 minutes to continue its way to the entire gas line.


Step #3. Getting rid of the cleaning solution

Release water from the pressure washer after you squeeze its trigger. Get rid of the cleaning solution coming off the detergent track. Next, rinse it off for the best possible results.


Step #4. Flushing the pressure washer system

Let the pressure washer operate for a few minutes after putting a detergent feeding tube to clean water. After that, get rid of the detergent from the pressure washer. Could you turn it off and get a hose replacement? Then, squeeze its trigger to free up the water in the line. You may also want to read about winterize and store your pressure washer
