Stellar Solutions Citri Surf Passivating Spray 2310 for Cleaning Stainless Steel Metal (22 Ounces)

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.

Spray on, leave for 30mins, rinse. Shiny stainless. Yer done.

Worked as described. I used SS tubing on boat transom ladder. It got rid of all surface rust and also some crusty rust spots on welds and fasteners. Nothing else would touch it.

I just received the spray bottle and noticed that the label was slightly stained, but the bag was dry. Both the screw cap and the cover were still on (by cover I mean the little cover that is pressed onto the top of the container that you have to remove before using (to prevent leakage). Not sure why but the label says 22 oz but mine had slightly more that 20 oz. (maybe 20.5). I guess not a big issue but frustrating when you pay for an advertised quantity and don't get it.

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.
