I use CLR for:

    * cleaning the coffeepot (rinse with vinegar afterward)
    * decalcifying the showerhead
    * removing rust from nuts, bolts, etc. hardware.
    * removing rust stains from the clothes washer
    * making copper pennies be shiny again

As others mention, after you clean rust off metal, it will begin
to rust almost immediately. I usually use a lubricant made by
BG Industries called 'HK' afterward, to prevent corrossion, but
sometimes settle for WD-40.

If you leave ferrous metals in too long, some ionization
process starts to leave a dark film on the parts. It looks
ugly, but so far, those parts don't further rust (but the
dark film looks like corrosion itself though I don't think
it is).
