Winter is upon us. How do you winterize the power washer and hoses? Do you guys just drain the hell out of it or do you guys use window wiper fluid?
 
I just drain and make sure one end of the hose is open to allow expansion of any ice. I used to blow it all dry but found it unnecessary.
 
I bring mine inside. I'd rather user glycol based antifreeze than wiper fluid myself as the wiper fluid has solvents that may not be friendly to the insides of the PW. They also sell winterizing fluid at wal-mart.
 
Karcher has a dedicated product called Pump Guard that you connect to the water inlet and pump in. Antifreeze, lubricant and is supposed to keep the pump and seals from sticking. I used it for the winter then didn't use the PW for two years, all worked fine when I fired it up.

I run few shots of WD40 through it then move it to the lower level of my home to sit out the winter months.
 
Be sure to drain the fuel tank, you do not want to have anything with gasoline inside the basement of your home, where there are multiple ignition sources, such as the water heater, furnace, etc.
