[GreenKeys] polishing knobs (not R-390)

[Ron Kolarik]

Plastic or Bakelite ?  Bakelite, clean with warm water and MILD dishwashing
soap, dry and polish with Brasso or other good metal polish.  Plastic, Novus
polishes or any of the other suggestions that have been floated.

Suggestions please for restoring polish to irregular shapes; Specifically
the black plastic knows on old (WW-II vintage) receivers such as the  RCA
AR-88
