Stains on SS after Citrisurf 77 treatment

[cyberpilled]

I just treated my entire truck and everything looks great overall except for one spot along the top of the door panel, I tried using more to get it out, but nothing is giving, what can I do to get rid of these stains?

I think this happened when some water from above dripped down while I was treating that spot.

The corrosion resistance of stainless steel is due to the oxidized top layer. The steel will actually degrade in an oxygen-free environment. It needs to "rust" (well, shiny rust from oxidation).

But that means the metal is interactive with the environment. The metal can take on slight discolorations, or change hue slightly over time.

For such stains, you'll need to remove a few atoms from the top layer. "Barkeeper's Friend" is your friend, so to speak. The liquid paste version contains fine abrasives that clean up the surface layer.

Start with a small amount, and light pressure. Repeat as needed.

Citrisurf is a mild acid, which helps dissolve free iron on the surface. That cleans it, and helps it shine. But it is not abrasive.

I've used both C77 and BKF with good results. Of course, if you make a shiny spot you'll end up doing the whole panel lol

i am afraid of using BKF due to how abrasive it is.

should I try BKF on the these thin stains? like with a q tip or something? so i dont cover too much area?

there is a BKF in a foam spray that works very well; you can find it at lowes, home depot, etc.

BKF is mildly abrasive. I've used it with a DA polisher. You'd need to really, really go out of your way to damage the surface. Either way, you're gonna make a clean spot hahahah

The BFK spray doesn't have the abrasives like the liquid. It's closer to C77.

I had good luck using the 'Tub O Towels TW90 cleaning wipes' to get rid of stains on my Cybertruck. Test it in a small spot first, with a little elbow grease.

(Eventually, I wrapped my Cybertruck with PPF, and a ceramic coating. It was much easier to keep clean.)

just tried a little soft bfk with a q tip and it made it way worse.

I am just going to have service try to buff it out for me.

If you do the whole top plane of the door it should even out. With BKF you need to rinse it after 1 minute. I recently did my whole truck with C77+ and had interesting drip staining, I thought about posting it but then just used BKF on the whole truck, it’s better but still has the drip line staining, not sure why. I love BKF though, it works so well on the CT.

i think it turned out amazing overall with the 77, so id rather wait and let them buff that out.

Tesla recommends against using CitriSurf 77+ on the Cybertruck, you should be using regular CitriSurf 77. Personally, I just stick with Bar Keeper's Friend Soft Cleanser, it has excellent results in combination with Windex or Sprayway.

I wish everyone would stop recommending bar keepers soft cleanser. It will polish the truck! You want the bkf foam spray and use it with a blue scotch pad to retain the brushed steel look. If you want the spaceship from flight of the navigator, use the soft cleanser....

Yes I highly advise against it. I was just desparate. What I did will be an easy fix with a buff job i think
