Evapo-Rust - Any Good?

[R. Pierce Butler]

According to all the stuff on the net Evapo-Rust is almost pure magic. Have anyone tried this on a cast iron table saw top? It would be nice to have the vintage top of my Unisaw look like new.

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.

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?

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.

Leave it alone until you're ready to sell it.

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. @;>)

Check out thier web pages:

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

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

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...
