Why is Winterizing Your Pressure Washer Important?

I have heard so many people ask this question, why should they even bother winterizing the pressure washer? First and the most important thing which every pressure washer owner should keep in mind is that they are supposed to keep it in a clean and dry place. When the temperature is higher, places like garages and sheds will work for you perfectly. But once the temperatures start getting lower, these places will not be able to provide enough protection. Especially, when the temperature is freezing, you need to take extra care of your pressure washer. Even if you store your pressure washer where the temperature doesn’t get too low, it might be able to work properly after a while. Like most of the other machinery, if pressure washers are not used for a long period of time, they will be damaged. 

When pressure washers are stored for a long period of time with freezing temperatures, they start to dry rot. After a while, you will find cracks in the pump system. If there is any fuel left in the unit, it will start going stale after almost 30 days. Not many people know this, but leaving fuel inside the tank can rot away the whole unit. There is ethanol present in the fuel which can lead to deterioration, which might cause rust, corrosion. other than that, it can simply clog up the fuel lines, which is the last thing you want to do with your unit. Also, make sure that there is no water left in the tank or hose pipe. In freezing temperatures, it might expand and freeze and as a result it might burst water hoses and pipes. 

Even if you are living in high-temperature areas, it is important that you thoroughly clean the whole unit before storing it. If there is any water or humidity is present, it might lead to mold or mildew build up.
