    Hi, I recently purchased a 2011 Premium one owner for my wife with 40,000. Car looks new and is super clean. I looked around but couldn't seem to find anything on cleaning oxidation off the engine block. Does anyone have any ideas? I can post pictures if needed.
    Thank you...

    Pressure wash? Just don't point the wand straight at electrical connectors or gasket seals.

    Dont use water under your hood. Use a degreaser or anything that can evaporate.

    Ok, some say its okay to hose off the degreaser. But using a power washer? That doesnt sound like a very good idea.

    Lots of people use a pressure washer, but you need to prep the engine bay
    before doing that. If you have any frayed, or going bad wiring, you'll
    tear them apart if you're not careful. We have a propane heated pressure
    washer, but it's not a high PSI washer because it heats the water.

    As oil and dirt builds up on the motor, it insulates it, and will retain more
    heat than normal. This is why you degrease a motor, and wash it down.

    Also, water and degreaser is not going to remove oxidation. You need
    something you can spay-bottle on, like an evap-o-rust solution, or that
    Dr.X rest remover. They' non toxic, and won't harm your skin, and you
    can lightly rinse it off. Plus the Dr. X stuff won't harm paint.

    Be sure to use something that won't harm the aluminum block. In the winter time the front of my block (2011 3.7L) looks like it is covered with salt. I try to wipe most of it off, only to have it return. Strange thing is it disappears and the block is clean and shinny in the Spring time when the weather warms back up :)

    I must add: I use Simple Green, gently scrubbing with a 'paint brush' then rinsing with low pressure water from a garden hose. Wiped dry with micro fiber towels :)
