The best antifreeze for a pressure washer must be able to withstand extremely low temperatures and harsh conditions, such as the ones you would experience when high-pressure water is involved. It is mostly important when people have to store their machine either in garages or at the basements to avoid the cold weather.
Antifreeze is used in pressure washers to help extend their seasonal usage. The antifreeze will prevent the water pump, wand, and other components from freezing completely. A pressure washer that contains antifreeze could allow you to use your machine in colder temperatures than normal.
The first thing you need to do before adding any antifreeze to your pressure washer is determine what type of machine it is. Cold water and hot water pressure washers are two different machines.
Cold Water Pressure Washer
A cold water pressure washer does not generate heat on its own. A cold water machine uses the temperature of the water from your faucet or garden hose in order to clean surfaces with pressurized water.
Hot Water Pressure Washer
A hot water pressure washer heats up the water using an oil burner or gas-powered heater which is attached to the pressure washer unit itself. This type of machine can get extremely hot, so it’s important that you only use quality antifreeze products that are designed for hot water pressures.
You therefore need the right antifreeze for a pressure washer. You may have heard that you can use a household antifreeze in your pressure washer (or maybe you’ve tried it). But don’t do that!
Household antifreeze is not certified for use in pressure washers. Household antifreeze is not propylene glycol, which is safe for pressure washers. Household antifreeze is ethylene glycol. Pressure washers have parts made of aluminum or plastic, and ethylene glycol will eat away at them.
If you have used household antifreeze in your pressure washer, you need to get it completely out of the machine before you use it again. If you do not remove all the ethylene glycol, it will quickly corrode your pump, radiator, hoses and nozzles. This could mean the end of your pressure washer.
What is the Maximum Idle Period for a Pressure Washer?
Power washers are like other machines when it comes to sitting idle. They should be run at least once a month to keep the fluids in the system circulating. The best way to go about this is to simply use your pressure washer once a month.
For most people, that’s not very practical. They may have only limited applications for the pressure washer — and it may be getting cold outside anyway. But there are some things you can do to make sure your pressure washer stays in tip-top shape when you’re not using it.
Keeping Your Pressure Washer in Tip-Top Shape
Run it regularly: If you want to maximize the life of your power washer, plan on running it at least once a month, even if you don’t have any specific cleaning projects you need done. For example, maybe you bought a new power washer for cleaning the driveway and sidewalk but don’t really have much else around the house that needs cleaning. So, find something that needs cleaning — or at least spray water on something for a few minutes. This will keep everything lubricated and prevent rust from forming up.
