Thanks for posting this. I have been wanting to try it out, but, its not available locally so I would have to mail order it, and I never knew if it was worth it. I'll try the sample and see what its like!
I have been into Espresso machines and such for years and before that knives and Mexican Copper work. I first ran across Flitz, in the pressurized can, during the late 80s and found it less messy than Brasso and Simichrompoly.
It worked well for me and I still use it for some jobs. Very similar to 3M's fine car polishes. Especially good for DE razors after using "Wright's Brass Polish" to get the soap scum off.
