CitriSurf 77 Stainless Steel Passivation Cleaner – Commercial Grade (22 ounce)

Be sure to read the instructions. Or if you don't, just read this: Wash the CitriSurf OFF your Cybertruck after scrubbing the Cybertruck with it (after letting it soak, after spraying it on). I didn't let it soak a full fifteen minutes because my Cybertruck was brand new and very clean with no residue (probably didn't need to clean it at all before applying the Sharkhide.And follow the instructions on the Sharkhide also (a Youtube review has a discount code, go look).

It worked to passivate nascent rust stains when applied twice per instruction

New stainless steel cable deck railing started to show signs of rust- this is what took care of the problem. Easy to use and protection for a while

Didn’t seem to clean the stainless I was working with at all. Tried multiple times while scrubbing.

I love this stuff but it is expensive. I use it on some brushed ss railing beside the ocean. They tend to rust for the seawater but this stuff brings them back to new with no scrubbing at all just spray them on a sunny day and let it sit.
