Re: How to clean a IIgs case...?

["Keatah@worldnet.att.net" <Keatah@worldnet.att.net>]

I'm currently experimenting around with various mixtures of alcohol,
bleach, comet, soap and other chemicals. So far i've found a few
mixtures that tend to lighten the cases. I also have to determine when
to stop and what the long term effects are. Any chemical that bites into
the plastic to work will need to be removed with temperature cycling and
neutralizing agent. We don't want this acting over a long period of
time.

I'll post my results once I feel that nothing messes anything up. I am
avoiding anything that is more than mildly abrasive or stuff that melts
plastic. yadda yadda..
