Hey,
I need some help. I ran across an article not to long ago about treating rusted machine surfaces. I believe it talked about using Amonia and talcum powder. I can’t remember the proportions, or if this even right. Can you wizzards dig deep into your hats and help me out.
Thanks, woodchuckbob

23990.1 discussed talc for rust prevention but I don't recall anyone saying it is good for rust removal. (BTW I'm looking for a good web/mail order source of quality fragrance free talc, haven't found one.)
When I discovered the error of my ways (not cleaning and waxing often enough) I used a suggestion from one of the mags: green Scotch Brite pad on hook and loop random orbital sander, lubricated with light machine oil. I used Norton sharpening oil. Worked well for removing small spots with little effort.
Ram,
Thanks for your helpful input and the other sources. Shall see if I can find a good source for Talc. Really appreciate your time and input

Bob,
Lots of sandpaper going from course to fine, stop whenever you are happy with the finish, wipe everything down, you can use mineral spirits if you want it really clean, then give it a coat of Topcoat and wipe down. After I've cleaned up these surfaces I like to go over them periodically with a fine silicon abrasive spunge that I got from Lie Nielsen in the tool maintenance kit. Then a fresh coat of topcoat.
This is a messy job so don't do it near your projects of touch anything afterwards that you might stain.
There is also a product called rustbuster if it's really nasty, that will flake off some of the old rust and nuetralize the surface. I've used this on structural steel beams, then gone over them with a wire brush in your grinder, but this method would seem to aggresive to me for a tool surface.
Apart from that have everything remachined, but get ready to spend some $$$$$.
Good Luck,
Brian
