    Not 100% sure, but I think the battery pack is encased in aluminum. Much of the rest of the undercarriage will be aluminum from the body, and most of the major suspension parts are aluminum, so no issues there with salt corrosion. The motor casing is likely stainless steel.

    A spray from a hose should be plenty to remove road salt. Give it a good blast in each wheel well and under the body, particularly around back by the motor, and you should be fine.

    I washed my car last weekend, and left the key in the car and had the door handles retracted. The two-bucket method is the best way to wash. When I was drying the car, I just extended the door handles and dried each one with no problems.

    One thing that was difficult was getting under the windshield wipers. I couldn't figure out how to put up the windshield wipers. I usually keep it up when i'm washing my other cars. The frunk was blocking them.

    Unfortunately salt corrosion is​ an issue with aluminum.

    Galvanic corrosion can be an issue with aluminum where it is in direct contact with other metals, like steel or copper, but that can be readily mitigated by keeping the metals separated, either by design or use of insulating materials between them where they must come into contact, like bolts. I presume Tesla has knowledgable materials engineers on staff and they did the right things here. If so, salt will be a non-issue. If not, then indeed there could be problems over time.

    Aluminum, on its own, can be directly exposed to salt water for decades with only minimal surface pitting and no reduction in strength.

    The touchless wash I use does, but if you buy a less expensive wash package, you can get it without the undercarriage spray...

    It's been discontinued? So they still sell the supplies for it at least as I still have the system.

    Supplies are discontinued as well (I still have the system too). I have been able to find some supplies on eBay in the US, but there are apparently restrictions on importing "chemicals" into Canada. There was a discount store near me that bought up a bunch of "remainders" the filters and soap, but they got cleaned out (pardon the pun) before I was able to get there and stock up.

    For those that don't know, the big claim to fame was the special filter that created a perfectly contaminate free rinse, and the car would air dry to a perfect shine (no water spots) without any toweling off.

    No, steel. In the NatGeo Factory film, at 41.50, it's mentioned.

    Ah, cool. Thanks. Makes sense for the extra armoring and better containment of catastrophic thermal runaway.

    Here's hoping that big slab of steel is properly insulated from the big hunk of aluminum (the body) it's attached to.
