    No, you don't want the detergent to dry on contact. Kind of defeats the purpose of using it.

    Here's a full resolution image (2816 x 2112) I just snapped - this is a 6+ year old WRX:

    Yes, provided it's a cold engine and you take care with the hose. The variable nozzle makes it easy. In years past I did do this on warm engines, but was very quick about getting everything rinsed - I did the bay in smaller sections. A cold engine is far better.

    3 of the cars I've done this with had distributors and I had zero issues (the WRX is the first with coil packs). 2 of them went over the 100k mile mark and had them for 8 - 10 years. All had the original alternator when I parted with them.

    All it takes with the WRX is 4 or 5 cleanings a year. 2 or 3 might do nearly as well.

    Think I might make a sticky on this subject ...

    Cool right on. So for the hose setting, would you want something with a bit of power or more of a mist?

    Depends on where you are squirting. It's mostly common sense; potentially sensitive electrical areas get a lighter spray, other spots can get a stronger stream. I've always done this with cars from the time they are new or nearly new. Engine bays that have never had a cleaning would take more sessions (many?) and will not look as good as one done from new.

    I use something similar to this (dang, this looks like a nice one ...)

    I think I know what you are referring to ... I don't think there is much you can do for that. Several engine bay cleanings over time may reduce it somewhat.

    Post up some good close up pics to be sure.

    Yes, that is corrosion ... on the aluminum (white spots) and steel (red rust). Whereabouts do you live?

    It would take quite a bit of work with a small wire brush to carefully and selectively remove the worst of it, but could be done. It appears nearly every steel fastener has some rust on it. Did the car sit for an extended period?

    The rest of the engine bay actually looks quite good.
