Hi Scott,

I thought we were discussing removing smoke smell? As long as the
brown tobacco stains remain on the radio, it is going to smell like
a chimney everytime it gets warm.

I forgot to mention the 409 vs bakelite problem. Most cleaners will
wash out the surface color from bakelite.

as brown as grasshopper spit.


That's a different problem altogether. In that case, 409 is VERY effective
at removing the gum, as long as you keep it off of phenolic parts. It will
etch bakelite very quickly.
