I have a bunch of street plate steel, that I want to magically
transform into welding tables.

They have rust on them, it is not horribly deep, but it needs to be
removed.

What is the most efficient way to do it using, say, a 9 inch angle
grinder. What abrasive things are best for it?

I am interested in the answers that will come. For me, I would investigate
the possibilities of some sort of acid wash, followed with power wash.
Don't know if it would be a good thing to maybe hook up a floor polisher
with an abrasive pad, but I am thinking on staying away from the big grinder
idea, and going for a method that would be very easy. After that, I would
maybe consider soaking it with cooking oil and heating it with firewood,
just up to 350 F. to put a sealer on it. Maybe others will suggest a better
easier way.

After my last tangle with a grinder, I am not so fast to draw it out as my
first choice, and that 9" can be a mofo if you mess up just a little.

MHO, will follow the thread and see what is suggested, at times I need to
derust large areas, sometimes full lengths of 20 feet. I would only build a
bath for those if I was to get into a lot of it, but if I was moving that
much tubing, I'd keep just new oiled stock in the racks.
