Cybertruck engineer pushes back on claims that Tesla EVs rust in the rain — “It's surface contamination only and can be cleaned off easily.”::A Cybertruck engineer, Wes Morrill, addressed claims Tesla's truck rusts in the rain and said the specks of rust were the size of a "pinhead."

The Tesla Cybertruck washcloth:

surface contamination only

That's my engineer LOL

Didn't he know that the surface is the most important part? Surface is everything!

And this is why you don't buy stainless steel sinks and cars, unless you want to polish them regularly they will look like shit even just from water stains.

Edit: Stop telling me your sink doesn't have rust on it. I'm not talking about rust. Most stainless steel will not rust. I'm talking about how stainless steel can become ugly from residual water marks, staines, water with high mineral content, etc Unless you take care of it, clean it and polish it regularly. Maybe ideal for a kitchen surface but not for a big ass ugly car.

Just wipe it down, then.

Stainless steel which has been sufficiently alloyed with Chromium won't rust. The chromium reacts with oxygen at the surface and forms an inert layer preventing oxidation of the iron in the steel. Cybertruck's stainless steel simply doesn't have enough Chromium.

30 years of a stainless steel sink without any rust

Never seen a rusty de lorian.... just sayin'

[–] [email protected] 1 points 9 months ago

Have you ever seen a rusty Cybertruck? All this talk is based off one single forum post from an owner who didn't even know what he was photographing.

[–] [email protected] 8 points 9 months ago* (last edited 9 months ago) (3 children)

It happens, and it's a very sad sight indeed.

Edit: Yeah, that one is a fake. Sorry about that.

Doing an image search, there are a lot of real ones in various states of decay or oxidization. Certainly takes a lot more time (and straight up abandonment) for a DeLorean to show damage.

[–] [email protected] 9 points 9 months ago

Yeah but like outside of this AI image have you ever seen a rusty DeLorean?

Using technology from the present to depict a past relic in a state it'll be in the future

[–] [email protected] 2 points 9 months ago

You just have to think fourth-dimensionally.

Obvious AI-generated image is obvious

Rust grows once it's punctured down, everyone knows this, no? I guess they only test cars in Texas and California. Still like the trukk

[–] [email protected] 4 points 9 months ago (1 children)

What do you like about it?

[–] [email protected] 2 points 9 months ago (1 children)

I live rural and driving a big ol electric brick is my dream XD

[–] [email protected] 1 points 9 months ago

Me too, better options than a stainless steel liability though.

Contaminated by what? CONTAMINATED BY WHAT MOTHERFUCKER

Most likely metal dust, called fallout by detailers and "flying rust" by some. Mostly comes off brake discs and railroads and other things that grind ferrous metals.

Common pest for anyone washing their car. There are chemicals that are useful. Mostly those smelling of eggs and turning purple on contact with iron.

[–] [email protected] 9 points 9 months ago

You can buy versions of it that don't smell like eggs, though they never smell good. That it turns purple is convenient when you spray it off, imho at least.

Cybertruck engineer pushes back— by admitting it is rust

I wouldn't call polishing your car every three days "clean off easily"

[–] [email protected] -2 points 9 months ago (2 children)

You don't polish stainless steel. That's something you do to correct paint.

This is the best summary I could come up with:


Over the past week, some new Cybertruck owners have taken to social media to complain about what they say are spots of rust on their brand-new electric vehicles, which cost up to $99,900.

Justin Demaree, the host of the YouTube channel Bearded Tesla Guy, said in his video on the issue that a Cybertruck owner had brought the truck to him the day after it was delivered when he'd noticed the specks.

In his video, Demaree said the tiny orange specks were probably the result of "rust dust" or particles that had landed on the surface of the truck and embedded into the material.

Demaree told Business Insider he'd seen the issue before but said the Cybertruck seemed to be even more prone to collecting the dust, probably due to its stainless-steel exterior.

The YouTuber tried a handful of methods to address the issue, including wiping the car with Windex and a liquid form of Bar Keepers Friend.

Correction: February 20, 2024 — An earlier version of this story included a photo caption that misstated when Cybertruck deliveries began.
