I've been getting some reddish scale formation on pieces I've heated in a
cobbled together propane forge/furnace/kiln, and it is very hard to get rid
of!  Will a better designed and built forge prevent this?  (I'm thinking of
those unburnt gasses you mentioned) 

If the red scale formation in a propane forge is unavoidable, does anyone
know the best way to remove the stuff? So far, a hot pickle, a wire brush,
and LOTS of elbow grease have barely touched it.

Thanks in advance,
Lee

Lee,
  Denatured Alcolol and a cloth, then hand wire brushing.  There really 
isn't any preventive to the red scale, it's more like a stain, but if 
your finish isn't too coarse, the alcohol should get most of it off.
