Argh. Pots and pans are great, but they do accumulate grossness after a while. Consumer Reports says everything they tested work pretty well in cleaning off ordinary stains fro msheets. But, what about really getting the junk off of stainless steel pots and pans. It is a brown film of cured oil.
I tried Bar Keepers Friend which was a sample from Calpholon One. It worked decently well to clean a really burned stuff, but left some residue. Apparently there is water based which works OK, and oil based which is toxic and horrible but works. There is something called Bayes Cleaner which says it is eco-friendly and works.
