Easily removes rust and stains from high end boat refrigerator doors
Works very well for spots and rust on stainless steel boat refrigerator door. Very expensive but worth it!

Normalize stainless welds
I had to weld and re-grain some #4 finish stainless steel. All parts were washed down to normalize the surface to prevent rust. Spray on, let it set and rinse off. Follow the directions.

Does NOT passivate.
Don't bother this was a complete waste of money. It doesn't passivate for sure, I don't know how well it cleans, but it's definitely not a clean&passivate product like advertised. I want my money back.

Spray on, rinse off
Spray on, leave for 30mins, rinse. Shiny stainless. Yer done. the only caveat is the white residue it leaves which must be physically wiped off

Same as CitriSurf 77
In reading the descriptions of the 2310 Gel and the 77 spray you'd think there was a difference in utility. There isn't. They both do the same job. The only difference is that one is a gel and the other is a watery spray. The product bottle labeling and directions are exactly the same aside from the model number. It works! Stops rust on stainless steel in a marine environment.

Make Certain You Are Cleaning REAL Stainless
It's probably the "stainless steel" that the made-in-China dog wash is made of, but this product took the finish right off
