Can you pressure wash underneath the hood of a car?

I looked underneath the hood of my car, and wondered if I could go to the car wash, and wash underneath the hood with a pressure washer? I've seen this done before, but I think there are certain area's you're supposed to watch out for such as the engine or something like that. Does anyone have any experience with this?

Answer
Nothing should happen by pressure washing under your hood. However i wouldn't take the risk. There is a chance you could water log your alternator, short some wires, screw up a starter etc. I would suggest a degreaser instead. I prefer to use Simple Green.

Are there any pressure washers that have its own water tank?

Minnus

I am looking to wash the undercarriage of my car. I live in an apartment, and don't have access to a water source. I am finding it impossible to find a pressure washer that has its own tank. The few I found seemed to stop selling in the US (Nomad pressure washer comes to mind).

My car has a special paint, and cannot run through a car wash. I think I can use the self-service, but if there is a different solution, I would like to go that route instead.

Any advice?
Thanks for the advice William - I sadly moved into a big city for work, and all my friends have similar living situations :'(

Answer
none that i know of,
how about a Friend who has a house ?

Can I use the "engine cleaner" setting at the car wash to wash my engine bay safely?

Nick

I have a 2002 Mitsubishi Lancer, and I really want to take it to a car wash and use the pressure washer to clean out my engine bay. Other than not spraying the filter, is there any reason NOT to do it? I've heard some people say their car wouldn't start afterwards, some people say its okay but to leave the car running... Which one is it?! Any help would be awesome.

Answer
Usually yes. Although when you use the pressure washer you should avoid or at least be light on the electrical connections. The connections are sealed however there is always the chance that a seal could be bad or not tight. It's also not a bad idea to avoid the altenator. Other than that there is absolutely no problems with washing your engine and bay with a pressure washer. As far as leaving the engine running it shouldnt matter and could actually be worse since it keeps your headers hotter. This could potentially but unlikely cause your headers to crack.

Should I wash my rug at the car wash?

PlasticTre

I got the idea from my friend. He said that's how he cleaned his mom's rugs.

One of my dogs has white hair and sheds a LOT. There are white hairs embedded in the rug that I can't get out with the vacuum or carpet cleaner.

If I use the pressure washer at the car wash.. will there be any drawbacks? Can it damage the rug? *It's a huge cheap rug anyway from walmart*

Answer
Sounds like a good idea but the only thing is it's going to be sopping wet, how are you ever going to get it dry. If you have a truck you could put it in the back of it once clean then take it home and hang it over a fence or something. Good luck!:)

I would just shampoo it with a shampooer.
