[R-390] Cleaning chassis suggestion

[Barry Hauser]

Tobacco "crust"?  The tar deposits from smoke generally come off easily with
many cleaners, though may take repeated wiping down.  Are you sure you
didn't strip off the MFP coating?  It's of similar color, but very tough and
usually has a gloss to it.  Not particularly a good idea to remove it and
it's somewhat hazardous when loose -- it's a varnish laced with mercury
compounds and other nasty stuff.  Many more times hazardous than tobacco tar
with traces of nicotine.  Not aware of any casualties though.
