Yeah,   I'm thinking since I want the keys to match the rest I think I might just wipe the whole thing down with some 409 and a cloth or something similar,  and call it a day....  No painting or Retrobrite.

Thanks!

I've done retrobrite 4 or 5 times, and it works, but still needs a post-cleaning... so yeah; PITA
I've used regular drugstore Peroxide with the Oxy and it still works. Honestly it evaporates fast in the sun anyway.

More often, I use this with a toothbrush and then a cloth::

It won't knock out keys or spots that are super uneven without some elbow grease, but it works.
At the end of the day... yellow computers work like white ones, and painting always gives you the risk of fuming later or binding. Even a light scrub with 409 and a soft cloth will do a lot, if your not up to buying something and scrubbing.

There was a really good thread about this on 8bc. Maybe you could find it here: https://archive.org/

I'm planning on modding my C64-C soon,  and I figured I would clean it up once I take it apart.  The plastic is very yellowed from age/smoke(?) ( I bought it used ),  so I was wondering what is the best way to clean the shell of my C64-C?

I just heard of retrobrite,  would that work well for this type of plastic?  Has anyone tried this?  Sounds sort of like a PITA (?) but worth it if it would work. 

I also wonder if I would just be better off painting it,  but then I would have to paint the keys too,  which seems difficult...

Any advice???

Thanks!!!
