Sounds like molasses and water. Or perhaps the derusting
compound found in molasses, and water.

I haven't tried it myself, but if you google this newsgroup you
will find it discussed.
I have use the electrolysis method with spectacularly good results--
except for when I got the polarity backwards...

Not going to happen. The rusted iron/steel is gone for good, so when you
remove any rust, what you have left is pits and holes. No magic formula
can replace that missing metal.

Sorry, but I have no good experiences to help you here. I have an old
knife that is stained as you describe, and I was never able to restore
the colour. If you find something that works without damaging the metal,
please let us know.

Maybe I should not have said "like new". It seems that cast iron and
possibly steel, oxidizes in layers so to speak. The obvious is the red
rust and that is easy to remove. There is a black oxide that forms under
that and that is tougher to remove. I was looking for an easy way to
remove that black oxide. Maybe I shouldn't? The top in question is very
smooth to the touch after cleaning it with a 220 grit RO sander. the
original grinding marks are still visually evident. I might post pictures
of the top so you can see what condition it is in. Anyway the question is
should I go for appearance or leave well enough alone?

I doubt I will sell it. I doubt I could find a buyer anyway. Who would
want to buy an old cast iron heavy monster like a 1943 Unisaw with original
owners manual? Everyone wants new saws that are lighter, shinier, and look
so cool. I am just an old fart that keeps what he has, 'makes do' and
suffers through it all because of it. @;>) <-bad hair day too

Will molasses mixed with water work or is that a really messy ordeal with
minimal results?
