I have always just connected my PW to my air compressor and strapped the gun open for a few minutes.

I just install a new pump, so is this "adequate" ? How about windshield washer fluid or RV anti-freeze ?

I use a can of "Pump Saver" it's an aerosol that is applied through the hose inlet that coats the pump with an antifreeze of sorts as well as lubricates. I also use Stabil in the fuel. Both provide f I r easier starts the following season.

I bring it down into the basement, along with: paints, chemicals and anything that isn't supposed to freeze.

I have bought a gallon of RV antifreeze - stick a cut off garden hose in it and **** it through the power washer. I have also just drained the gas and brought it in the house. It has set in the entryway all winter.

I don't have room for the whole washer inside, so I remove the pump. Drain it and lub it and put it in a zip lock bag. Store inside.

My manual recommended RV antifreeze. I've used it for about 4 years now with no problems

I hope you guys drain all the gas from the engine before storing indoors.

For mine, I top of the fuel tank with gas treated with stabil and heet. Then fog the engine until it stalls. Then feed some pump saver in while slowly pulling the starter rope.

You don't need to use RV antifreeze - I use used automotive antifreeze that I typically have a bottle or two of around at any given time.

I made a hose fitting adapter that screws onto the pump's water input and has a right-angle pipe fitting with a short stub of pipe on it sticking straight up. A short piece of 3/4" heater hose on that, with a plastic funnel on the top.

I pour a small amount of the antifreeze into the funnel, and then cycle the pump over by hand a few times until each cylinder in the pump has anti-freeze in it.

I use a 3' piece of hose connected to the inlet. Fill the hose with RV antifreeze then pull the cord till pink stuff comes out, add more to the hose if needed. Disconnect the hose and pull the cord a few more times. The pressure washer is stored in an unheated shed in Northern Maine where the temp can drop as low as -35 deg F. Been doing this since 2001 with no issues.

Leave it to GJ. When I got a pushmower out today, I thought about this topic and considered making a thread about it. RV anti-freeze was my first thought to use. I guess I'll grab a jug in the morning. . . . before I forget.
