Detail companies like armorall because its cheap and it does the best clean.I used to be a PDI and Make-Ready worker at Don McGill Toyota and while i worked there, i learned the best way to detail your engine bay. Its simple, use ArmorAll, the same armorall you use on the interior, use it under the hood, let it sit for 10 seconds and wipe it down with a lint free cloth, armorall also works as a tire shine Hope this helps
See, now back in my day, I was told that you should have the car running when washing it with water!? But then again, this was on cars 10 yrs ago! And yes, I do not spray directly onto electrical parts.idk if any one else suggest this, but i always just spray it down with degreeser, cover any visable electronics with plastic, and do a real quick/light spray with a pressure washer.... then to top it off, spray a cover of armerall over all the plastic/rubber things... dont start your car for a good hour or more after doing this tho... besides the water all over everything, the armorall will attract even MORE dirt before it drys up a little bit... if you wanna keep it looking shinny and clean you gotta do this like once a week.

But also it makes it so the engine bays get dirty again faster. So people come back more often.
I don't know about that.... If you have a motor that's been to hell and back you will need either a steam cleaner or a pressure washer. It's not that they're bad, you just need to know a little bit about what you're detailing. Like the LT1 car in my previous post, I used a pressure washer on all of it, I did however cover up/steer clear of the Optispark dist. Unless you have leaky gaskets/seals where water can enter, you'll be goodDon't use a pressure washer under the hood.
You'll get a hundred people that will swear that they've done it their entire lives and their dad did it his entire life and their dad's dad has been doing it since they bought the very first pressure washer ever to be sold to consumers and have never had a problem.
Smile and nod when they say this...then go home and when it comes time to clean the underhood area don't use a pressure washer. Cars are made to wishstand rain, not hurricanes.
Soap and water in a spray bottle or some gentle cleanser and a wipe down. Get the areas you can see if they bother you that much.
