A friend of mine told me about using MOLASSES to remove rust stains on stainless. Yes you heard right MOLASSES!.
I gave it a go and it worked leaving the polished stainless unmarked. I painted it on left it a couple of days before hosing it off - perfect.
It appears that the reducing sugars in the molasses causes the iron III to be reduced to iron II (soluble).
Thought this might be useful

Fascinating, wonder if it would work on my rusty iron keel ?
I have used it for removal of tea staining.
I know a friend of mine has used it on revitalizing tools.

Remarkable! Who'd a thunk. Thanks for the tip. Keep 'em coming.
