is there a tank/sprayer combo with enough PSI to wash a car?

I see that most tank/sprayer combos have maybe 100 PSI, which seems suited just for applying chemicals for agricultural purposes. It seems that most sprayers for car washing applications are at least 1200 PSI. I just need to be able to wash off top layers of dust and dirt and saturate a car for hand washing, but 45, 60, 100 PSI all seem a bit low to me.

Can I pull this off without purchasing a tank and a separate pressure washer?

Links would be greatly appreciated, thanks.

Answer
Go to Walmart they sell various pressure washers of different PSI. I wouldn't get over 100psi or close to that, so you don't peel paint and blow window seals.

How can you adjust the PSI from a pressure washer?

Hello,

I am looking into purchasing a pressure washer for various uses, they are pretty affordable from what I can tell, however for a few applications I need a level of pressure around 1200, no higher. If I use any higher there may be damage done by the water. Is it possible a pressure wand can have an adjustable max pressure? Or perhaps just being careful enough to keep the nozzle far away enough?

Many pressure washers seem to be in the 1500-2000 PSI range.

Thank you.

Answer
My parents craftsmen pressure washer has a 2400psi max pressure. However the wand is adjustable so the spray can be more or less concentrated depending on what you need. Also the engine has a throttle control. "Turtle" speed makes a good bit less pressure than "rabbit" speed. Also the water loses pressure very fast once it exits the wand so just holding it back a bit will be enough. Hope this helped.
