I have an old exhaust fan from the 50s in my kitchen; the kind where you let a bead chain loose and it opens a hatch and the fan engages. Anyways, the fan has a metal faceplate, and a stainless steel grill in front. I cleaned the grill up and it's shining nice now, but the metal faceplate (which also holds the fan attached to it and the whole thing is then screwed into the housing) is covered in probably 15 layers of paint over the years. There's some pink, then green, and yellow over that, and then white, and probably plenty of other layers I can't make out. What's the best way to remove all that paint? I want to strip it down to bare metal (it can be submersed in something if need be), and then I will either try to finish the metal (don't know where to start there), or I will just paint it again to match my refinished kitchen.
So the meat of this question is, how to strip 60 years worth of layered paint from a metal faceplate so it's down to bare metal again, and if I were to finish the metal, what are the options there (i think it's steel)?
