[Robotgroup] Clean/polish plastic?

[Tami Friedman]

I have had success polishing the plastic lens of a (cheap) compass with  Zam
applied with a buffing wheel, running slow and wet (to keep the plastic from
melting).  Jewelers' rouge would probably also work.  Zam has a bit more
abrasive than the standard red jewellers' rouge, but we use it as final polish
at school.  Refresh the abrasive often and use a muslin buffing wheel that
will polish a largish area and keep a light touch. 

Liquid detergent or ammonia will remove the greasy buildup from the abrasive's
binding material.

When I want to de-label a plastic container, I use WD-40.  That won't help you
now, but maybe in the future :)

I'm not a robot, but I played one on TV.
