Stainless steel is a self-protecting metal no? Washing it with dishsoap would be shortsighted. There's also a absolute ton of stainless alloys, no idea which one they selected for the exterior panels. Curious if they'll survive Colorado winters with the salt.

Colorado doesn't salt the roads (for the most part anyway). They use de-icer, sand, and gravel.

  De-icer is basically salt.

    Not always. https://en.m.wikipedia.org/wiki/Deicing https://en.m.wikipedia.org/wiki/Deicing We use the glycols on aircraft and some electron equipment

      Yes, but not on roads…

  Magnesium Chloride is used in most parts of Colorado. It's absolutely terrible for your car.

    Beet Juice is the best de-icer. Its just expensive. - Beet juice is better because it doesnt kill the FN trees + flora... Source, grew up in Lake Tahoe - Salting the roads killed the ice AND the trees on the side of the road. Also, my grandfather and great grandfather on my stepdads side were beet farmers in Idaho.... and yes - beet juice is WAY better for the environment, but you have to do all that farming first. Then Juicing, then trucking then....

      That’s the first time I’ve ever heard anybody say that. Places use beet juice because it’s cheaper than calcium chloride and it works terribly.

  "salt" used colloquially as "de-icer", but MgCL is also "a salt" scientifically speaking.

>There's also a absolute ton of stainless alloys, no idea which one they selected for the exterior panels. 301, a less expensive option with very poor corrosion resistance compared to other stainless steels! 304, which is more corrosion resistant, is used for unpainted train cars, and those aren't even exposed to road salt!

  What's your source on it being 301 stainless? All I could find was "30X" – which could be anything.

    https://www.sae.org/news/2020/06/tesla-cybertruck-stainless-steel https://www.sae.org/news/2020/06/tesla-cybertruck-stainless-... From the Society of Automotive Engineers article: "'Tesla’s strategy with this truck is very interesting," observed Dr. David Matlock, professor emeritus at the Colorado School of Mines’ Advanced Steel Processing and Products Research Center. Reviewing Musk’s public comments on Cybertruck online, Matlock surmises that the material is 'very likely a modified version of the lean-alloyed austenitic 301 alloy.'" Two other things line up for me: the rate of rust is right and I think if they were using 304 they'd want to advertise it as 304, not 30X.

      I don't think we should say "it's 301" based on the "surmising" of a 3rd party who didn't look at the steel itself but rather "reviewed musk's public comments". He could very well be right, but that is definitely speculation rather than fact.
      - elil17 3y ago
        Well I haven't done the depth of research he has, but I believe a key piece of evidence is that in the initial Cybertruck announcement Musk said the Cybertruck uses the same steel as Starship. At that time, Starship prototypes were using 301.
