How to remove spray paint from iron?

Try using WD-40 - no kidding! It works wonders for removing spray paint depending on the type and how long it's been on.

You can burn it off as well....WD 40 may leave a residue and effect the taste of the coffee if you intend to grind with it.If the part is removable, and is all irom you can burn off the paint. I would reccommend MEK and steel wool as well. MEK ( or Methyl Ethyl Ketone) is an agressive solvent available at hardware and paint stores. It leaves a slight residue but breaks up most paints well. Use a rough steel wool grade like single zero grade.
