windsheild washer fluid works just as well as anything and is cheap. you need a short piece af garden hose and fitting to attach to washer. put the hose end in a gollon of washer fluid, turn on washer to advance the fluid throughout the pump...done.
few powerwasher tips...
try to get one that has a separate unloader valve, so that it can be repalced down the raod. a lot of the less expensive one's have this valve attached to the pump, so you have to replace the entire assembly if the unloader valve goes bad. (the unloader valve is what takes the "shock" of letting off the trigger)
also, a unit with a hose with standard 3/8 pipe fittings will allow you to buy a quality hose to replace the factory one when you burn it on the exhast (seen this a bunch of times) or it gets a hole in it. most of the cost effective units come with a POS hose & wand and have a goofy threaded fitting that can be tough to find.
make sure there is a valve & packing rebuild kit available for the model you choose. buy the kit when you get the washer, then put it somewhere you won't forget about....you will need it eventually.
gallons per minute is more important than PSI. you want the most GPM you can get. 3.0 GPM at 2000 psi will anihilate a 1.5 GPM at 3000psi.
do not pulse the trigger on the wand, (rapid depressing & releasing of the trigger) this will wear out the packing in the pump. look for a wond with quick change tips instead of an adjustable tip.
don't run the unit at full speed if you have a gasoline engine. it (the engine) will last much longer if you set the throttle at about 75%.
eventually, i will get a unit like this for myself...but have not had the funds available. (plus a buddy has a good one that is up for borrowing when i need it)
LOWER RPM Means Higher Pump Life Expectancy and Less Heat Exchange

one more thing...if you don't want to spend the cash, you can rent a good one at an equipment rental store for probably less than $50 a day. they can be found at the same places that rent skid steers, mini excavators, etc.
