Tesla's Cybertruck may not be so stainless after all

lol. Cybertrucks are looking like my sink.

They should invest heavily in Barkeepers Friend. Works pretty well on the sink.

It's relatively common for nice metal bikes to go the unfinished metal route...if they're made of titanium.

Even so, my friend's ti bike has stains on it that he can't get out sort of polishing/ brushing it

Tesla is just recognizing that each cybertruck owner has different color preferences, so they deliver the cybertruck without any paint or coating so the owners can coat it themselves /s

I saw one in person 2 days ago. I took a picture, and none of my coworkers think it's a real picture (or that I took it).

It was surreal. I could see it coming from WAY down the road and I was thinking to myself "there is absolutely no way I am seeing a cybertruck right now"

I am dumbfounded they actually made them. I still can't believe what I saw the other day

Stainless is not stain proof. Different grades of stainless have different levels of rust resistance depending mostly on chrome, nickel, molybdenum, and carbon levels, but even the most resistant grade will rust under some conditions. The primary method of rust protection, what makes stainless stainless, is a continuous layer of chrome oxide on the surface. The problem is that layer is weak to chlorides like salt or bleach so exposure to such can allow rust to begin. Adding more nickel, more chrome, and more moly can help but nothing is rust proof, even extreme marine grades like 317L can rust.

Edit: the cybertruck is made using their own "30X" grade. The most common is 304 or 18/8, which has around 18% chrome and 8% nickel. 302 has less, 309 has more. I would bet it is near 304 as that is the most common austenitic (nonmagnetic) stainless steel. This grade does not have the molybdenum added to "marine stainless" grades like 316 and 317. That molybdenum provides some resistance to chlorides which is why it is used in marine applications and commercial kitchens. It is also quite a bit more expensive.
