I'm curious if there are any common marketplace alternatives to Barkeeper's Friend since I live in a country where it's not readily available.

Oddly, it's not hard for me to get oxalic acid, but I'm not sure what the blend would be to get something that works like BKF.

I've got some stainless cookware and my range puts out hot flames, so I get occasional problems with brown spots, and hate taking scotch brite and 10 minutes to try to scrub it away.

Any advice would be appreciated.
