Nick is a Tesla Cybertruck owner from Seattle, Washington, and says he was surprised to find his Cybertruck’s stainless steel exoskeleton rusted and corroded after he attached a magnet to it.
Nick shared his experience on the Cybertruck Owners Club forum under the title “Don’t put magnets on your Cybertruck! Corrosion?”
Here is what Nick wrote…
“I feel like an idiot. I decided to put advertising magnets on my Cybertruck. I happened to take them off to wash the truck after a month, and my heart sunk…rust and corrosion.”
Below his post, Nick provided several pictures of his Cybertruck, showing the discolored and rusted stainless steel along the lower portion of the passenger side door.
If you head over to the Cybertruck Owner Club forum, you will see that Nick’s Cybertruck is extensively stained, with white central blemishes surrounded by brownish-rusted-looking outer defects.
This is an interesting case. Ever since Tesla revealed that the Cybertruck would have an exposed unpainted stainless steel surface, there have been questions regarding rust and corrosion.
Continuing his post, Nick writes…
“I was able to clean most of it off with liquid Bar Keepers Friend, followed by Windex, but there are a couple of small white spots left that have a slightly rough texture. I am planning on using a cordless polisher with my Bar Keepers Friend to see if it will just take a little more than elbow grease to polish it off.”
After the cleaning procedure, Nick shared more pictures showing that most of the superficial blemishes are gone; however, the deeper, white corrosion with a rough surface is still intact.
Finally, Nick writes…
“Does anyone have any recommendations for removing the rest of these small spots or know what exactly is going on? I like to assume the spots are just superficial corrosion with good stainless steel underneath still…”
This is the first time I’ve heard of the Cybertruck’s stainless steel rusting after being exposed to magnets; however, other Cybertruck owners have come out and shared similar stories in the comments.
Another Cybertruck owner from San Diago who goes by the username “wh1t3rbb1t” on the Cybertruck Owners Club says…
“I had the same issue with a magnet on my Cybertruck, which is disappointing because of all the possibilities. But oh well. I wonder if we could place something between the magnet and steel that would allow it to stick but not allow corrosion.”
Since Tesla used magnetic stainless steel alloy for the Cybertruck, many owners were excited about all the unique customizations they could do to their trucks simply using magnets.
However, it appears from these reports that leaving a magnet attached to a Cybertruck might not be a good idea.
What’s going on here?
On the surface, since rusting is a chemical process, and magnetic fields are not supposed to affect this chemical process, the whole issue of the rusted Cybertruck is a bit of a head-scratcher.
However, a couple of factors could be at play here that are causing the premature rust on the Cybertruck’s stainless.
First, and the simplest explanation, is that road debris and moisture trapped between the magnet and the stainless steel caused accelerated corrosion.
This process can be further exacerbated if a strong magnet is used. This can cause surface scratches, expose the underlying metal, and make it more susceptible to rust.
The second possibility is that while magnets do not directly affect stainless steel corrosion, the type of stainless steel, whether magnetic or non-magnetic, correlates with its corrosion resistance. Austenitic stainless steel (non-magnetic) resists corrosion better than ferritic or martensitic stainless steel (magnetic), which Tesla uses with the Cybertruck.
Also, watch this interesting story of a new Cybertruck owner, who had to return to the dealership after 3 days of ownership on the Torque News Youtube channel.
Overall, it’s surprising to see the Cybertruck’s surface extensively rusted after being exposed to a magnet. Please let me know what you think is going on in the comments.

Magnetic stainless is the cheapest stainless there is. It is thin and has ferris metal in the mix. I'm not positive that the magnet had anything other then alignment of the molecular make up. Of course if the stainless alloy is not properly taken care of ie a corrosion preventative coating. It will rust. Just like any exposed steel. Look at your cheap stainless appliances after time without proper maintenance it rust. Good non magnetic stainless will last two life times even if not properly maintained.

Of course it is going to rust, magnet or not. The bodies on these trucks are 302 stainless steel. Not a true stainless steel because it has carbon mixed in it when casted. They had to use 302 because it was easier to stamp the body panels. If they had used 304 instead, other problems would be present in the stamping process. 304 is alot stiffer and harder.

Yes, certain types of stainless are magnetic.A lot of the 400 grades and the duplex grades are magnetic.it could also be thin enough for the magnet to stick to the support or parts underneath that are magnetic.

I is is stainless steel. Bro, it's LITERALLY in the name - Stain-LESS steel. Let me repeat... Stain LESS. It's not called stainproof steel. There are varying degrees of StainLESS steel with different abilities to... you guessed it- stainless.

Less than a minute of reading about stainless steel would reveal that being magnetic has nothing to do with whether or not a material is considered stainless steel. Even non magnetic stainless steels can become mildly magnetic under certain conditions.

If it was even mid-grade stainless steel, first of all magnets would not stick to it, and it certainly would not rust.

The Cyber truck is made from A300 stainless steel which has a much higher quantity of nickel in it so it should not be magnetic at all.... Look it up everybody

Nickel is a very good magnet, that's how you can tell a nickel that actually made from nickel.
The fact that the A300 SS has nickel in it supports the fact that it's magnetic.

It is a wrap. The picture they are showing is not the one from the businessowner. To see the actual corrosion you have to click a link and it shows a small line and two dime size corrosion spots. And those look like some kind of clear coat damage. The picture the article is using is totally deceptive.

Interesting, I woukd have expected Tesla to use a 3 series stainless for an automotive body application, as road salt is corrosive. 3 series are non-magnetic, wouldn't hold a magnet. They must have used a 4 series,such as 409 they use for exhausts. 409 is more corrosion resistant than carbon steel, but no where near as resistant as a 3 series. Probably trying to cut costs, maximize profits.

Unfortunately, I am not surprised at all.
Stainless steel can be corroded, about time to break the myth.
It can be corroded and often times very easily. Corrosion is an electrochemical process, and whether or not a metal corrodes depends on the environment to which is exposed and the composition and manufacturing process of the metal.
Low pH acidic compounds can be more aggressive to many steels than concentrated acidic solutions...
Anyway, the power of marketing.
