View Thread: Power washer


Sia Bani
I'm thinking of buying a powerwasher for my tahoe. Will the force of the spray ruin the paint? and how much do these usually run?

SLP Addict
NO DONT!, the force WILL ruin the paint, and i think they usally run about 100+(Trust me we own 4 of them)

Not necessarily bad. Just don't have it any closer to the paint than you'd have against your arm. That's the general rule.

I have one, but i don't use it. A hose and a bucket is good enough for me. But the pressure washer might help you get to hard to reach places on an SUV.

seriously man. That's the main reason why I gave up washing my own truck. I do the engine and stuff myself...but boy a powerwasher would kick ass.

I really don't bother washing my engine bay.

And if you know your car needs a cleaning and you're really lazy, the pressure washer is great.

get it. providing you are far enough away the force will have no effect on youre paint

Sia, go to Griot's Garage. They have this awesome Firehose style spray nozzle that fits on regular garden hoses. It's made of Alu. and Brass so it's solid and it has a rubber bump-guard thing on it. The spray from it is great for washing the car. Very high volume with medium pressure. The spray is adjustable also. And make sure you have a decent garden hose also. One that flattens out or kinks easily will hurt your pressure. Here's a link to Griot's...

And a link to the nozzle...

It's not cheap, but worth it.

Get the power washer, its worth it, it will not ruin your paint as SLP said. Car and Driver uses a power washer on all their cars, good enough for them, good enough for you =) Also, make sure it sprays in a wider shot, none of this stuff that could tear through sheetrock.

Ck, I dont' get how it could be 76 bucks for a nozzle though. What does it do differently than those 10 dollar ones? Just built to last??

Quit being cheap. Yes, it's all about construction. Solid aluminum and brass throughout. Not some cheap plastic or metal. And it is built to last. I think it has a lifetime warranty. Also, the spray pattern is awesome on it. Very even, with high volume which is what you want for washing your car. Volume is more important than pressure.

so function wise...it's the same as those 10 dollar nozzles, other than the "formation of water" that sprays out? I want something that will seriously remove crap not just on the exterior, underbody, engine...the ground...anything.

Well, yes it is pretty much the same function wise. It will not create pressure, but make the most of it. If you really need to remove heavy debris from the engine/underbody a pressure washer is the way to go. If you want the ultimate nozzle to wash the exterior with and not harm the paint, that nozzle above is awesome.

really that thing cant be that great, it can increase pressure by using a restriction, but it cant keep the same volume because that is limited by your water pressure from your hose. The power washer on the other hand does both. :green:

Sia Bani
that was really what I was thinking. If I wanted the utlimate garden hose, I'd get that nozzle. Let me put it in car terms...

I'd rather spend 200 dollars on a chip, than 75 on the nicesest altezzas!

It's good, but only as good as your water pressure is. The problem witha pressure washer is that it can't create volume, only pressure. You will only get as much volume as your hose/spigot can flow. But like I said, volume is what you want to wash the exterior paint. It gets the soap off better and most gently.

A-Tech
sure they get volume, dont they have a storage tank?

Ive seen some with a water tank and an air tank.

ckacyon
Maybe...but I think they just create pressure. I haven't heard that they actually have a storage tank. The pressure comes from compressed air usually which forces the water through the hose/nozzle at a higher rate. Over time, I think regular use of a pressure washer causes more harm on a paint than just using a standard spray nozzle. Think about erosion and what it does to rocks. Even some cheap paint on the leading edge of hoods/roofs of vehicles will peel from the effect of the wind. While they are great for the engine/undercarriage/wheels, I would not use one on my personal vehicle.

Oh and Sia, if you want a pressure washer get a Karcher. They're awesome. http://www.karcher-usa.com/

it really all depends on how powerfull the washer is. If you have to get a power washer, get one that guarantees not to damage the paint.

nice. I'll check it out. I just odn't have any room to be doing that while up here at school. Maybe at home.

just because I'm an idiot...I'd probably get one that says "caution, may damage paint." If I'm going to get something powerful, I'd rather have the most powerful and risk the paint by using "my judgement". hahaha, that's when I fuck myself.

A-Tech
like I said, dont go maniacal on it!

Let's see...

Either take it to a car wash and use the power washer there, or buy your own and do it at your house.

Same idea. I have a friend who washes his Prelude with a power washer. He has no ill effects from using it.

Les /Vipers Rule
NO DON'T EVER USE A POWER WASHER ON YOUR PAINT. You can and will damage it. Straight from the makers of Meguires Wax, they state NEVER use a high pressure water system on a cars finish. It will drive dirt through the clear coat and the pressure of the water will begin to lift the clear coat. Always rinse with a low flow sheeting action of a water hose. PRESSURE WASHERS will in all likelihood wear out your paint.

As for washing engines bays.... be very careful and agains never a pressure washer. Seal off areas where you do not want water seeping in and wash wish a soapy mixture first then a low flow rince. A pressure washer in the engine bay could force water up and inside electrical connections that you failed to protect resulting in shorts, electrical problems and/or corrosion. Be very careful when rincing an engine bay after you wash it down. Once you are done turn on your engine and let it run up to temp. and this will evaporate the standing water quicker.

A lot of times I just wipe down prominant engine aeras with a damp rage and do not spray any water in it.

I'll agree with Les. And I've been cleaning cars for almost 20 years now. I currently run the body shop. We recommend against using pressure washers on painted surfaces. The primary reason is because most pressure washers, the cheap ones that people by, have litle to no control over the actual pressure. If you can find one with a regulator and keep the pressure down, then maybe. No matter what, don't use it in the engine compartment, though.

I got lucky then. When I had mine cleaned, they steamd/pressure washed the engine. They blew the bulb under the firewall, but i got a free wax from them doing that! :bigbounce
