I use Spray Nine for plastics. I rarely use Magic Erasers unless there is
a scuff. If used to rigorously, it will smooth out any rough or pebbled
texture in plastics so use sparingly. For cloth, I use a microfiber cloth
and frequently wash them. I use Goo-gone for removing sticker residue. I
use automotive Brake fluid for removing paint but do so very cautiously;
trying a small part first to see how the plastic reacts.

I use a compressor to blow out loose dust bunnies, heavy layers of dust and
debris and other particles. I use isopropyl alcohol and q-tips for sticky
messes or leaky capacitor residue prior to washing. I'll remove all
removable parts and then wash in a sink with soapy water (usually Dawn) and
use a soft bristle brush to loosen up any crust. Naturally, you need to be
careful to dry it very well. In extreme cases, I have used a dishwasher
but I think I've only done this once.
When getting into corroded boards, I use a 50% vinegar and 50% water
solution and soak the board for a few minutes and use a soft bristle brush
or q-tip on the affected area then check results. I will progressively
soak for longer periods of time with a cleaning cycle until it gets to
about 3 hours. After that, I stop and that's the best it will be. I use
silver polish for edge connectors if tarnish but I use this very sparingly
as the contact material is very thin.
For keyboards, I will take them apart completely by removing the key caps
and cleaning underneath the keys as well as open the case and clean up any
dust or debris in there. I have been considering getting an ultrasonic
cleaner for the small parts like key caps or maybe even key switches (after
taking them apart) but haven't gone there yet.
I think this about covers everything I have done or tried so far. This
works the best for me but your mileage will vary.
Hope this helps.
