Cleaning the steel before cutting and assembly is ususally the way to go.
If it is really grimy, & you can dry it relatively easily, them you can
pressure wash it. Get rid of any standing water with compressed air or a
leaf blower afterwards. Buff with a wire wheel on an angle grinder (use
safety glasses and heavy gloves) to get ride of mill scale. Wipe down with
MEK or acetone and you're ready for paint. Industrial enamel primer and
top coat. Allow for complete drying between coats (24-48 hours).

Hi all; I'm approaching the stage where I need to paint the trailer
I'm building.

Can anybody give me advice or talk about their experiences working
with angle iron? The metal I'm using if filthy, coating my hands
black if I handle it too much. Is that coating some sort of
protective material or is the metal just dirty? What's the best way
to remove it? I'm guessing that a pressure washer isn't such a good
idea .

Having cleaned it, how do I paint it? What kind of paint do I use and
where do I get it?

Actually, anybody know of a paint shop on the SF peninsula that can do
a decent, cheap job?
