overnightYeah, I have a small chainmail scrubber and it's good for all kinds of cleaning tasks, not just cast iron.
Maybe I could make two cornish hens, one with the chainmail scrubber and one with foil to test this concept before committing any $$$.
KlipShort answer: It's just as good on Stainless Steel as it is on Cast Iron. It's just less necessary.
The idea behind using chain mail on Cast Iron is that the seasoning layer, as well as the iron itself, is soft enough to be gouged by aggressive abrasive scrubbers. Chain mail's hard but smooth rings allow you to apply more scrubbing force without gouging the surface compared to other scrubbers.
Stainless Steel is much harder, so you can use much more aggressive abrasive scrubbers on it without worrying about marring the surface. You could also leave Stainless Steel soaking in soapy water to loosen stuck-on foods. Or stick it in a dishwasher. Options you don't have with Cast Iron, which is why most people don't go out of their way to buy chain mail scrubbers for their stainless steel. But if you have a chain mail scrubber, it will work just fine on your stainless steel, or your pyrex/glass, or your finished ceramics*, or pretty much anything else in your kitchen.
*: Unfinished ceramics will actually abrade the steel rings of the chain mail. That's why, in a pinch, you can use the unfinished ring on the bottom of a coffee mug as a sharpener for cheap, stainless steel knives.
SitwonYou could just send me $30 and I'll tell you it's a waste of money. $10.28 savings and you won't have to figure out what to do with a piece of wobbly chicken coated metal. (maybe a "bath blanket" scrubber for cast iron cauldrons?)
