Power wash question

[edgemaster]

Guys, I have a, probably, silly question: I'm planning to buy a power washer. Never used one on a car and I am wondering if prolonged usage has any negative effect on the exterior (rubber, paint, clear coat, etc.)?

I'd appreciate any input pro or contra.

In my opinion, it is a great way to clean your vehicle. Especially the wheel wells and undercarriage. How much PSI is it? That would tell a lot about your question. 

Depending on how strong it is, you need to learn how to use it and not get too close to certain areas and parts of the vehicle.

The one I was planning to buy has 2000 PSI.

Any more input on my question?

I don't see how prolonged use would have any negative effects.  What you don't want to do is hold the pressure wand right up against any part / paint.  That might cause an issue.

 

Great tool as STBEAST already said.  Use common sense and you should not have any problems.

 

ALWAYS be careful if spraying around any electronics

I've never had good experience with the electric sprayers, they last a year or two. Have never had a problem with my gas sprayer, has a  Honda engine. 

 

Don't use a high pressure washer in your engine compartment. Followed this video few years ago and never had a problem.

Well, I have used a Kärcher since the late 90s and it lasted about 20 years, so no gas powered pressure washer for me.

I've had several Karcher's. Usually in the 2nd or 3rd year something goes wrong and I get the speed up—slow down, speed up—slow down on the motor/pump. Called Karcher and they told me what was wrong but wasn't worth fixing. 

 

Nonetheless, I'd never use high pressure in the engine compartment. (I have used the battery sprayer in the video and it's perfect.)

 

Gas has several advantages, lot more power, accessories, more flexible (not limited by power outlet.) Just get one with a Honda engine and known pump.
