Retro activity for the past few days: it was very sunny and totally cloudless for the past days which proved to be a very succesful attempt on whitening yellowed plastic. I used regular 12% Peroxide "hair-stuff" and sprayed it on cleaned plastic. I haven't figured out an exact water-to-hair-stuff ratio but about 25% water ought to do the job using a plant-spray (well, actually cold water spray with a fan but same idea).
Without further ado some pics:
Tried the casing first before touching the drives. Difference is clearly visible.
My first own computer; couldn't be more yellow!
Which cleaned up nice. I did the floppy drive a day later for a better overall result.
And while I was at it.. why not more stuff? 😀. The small Compaq bezel was very yellow and turned white again. It does have very little staining though. The white cover with the damaged logo (due to water) on the bottom turned out very good. It's cheap plastic and not as solid was the Compaq part- but sometimes cheaper parts turn out better 😉.
All in all I'm very happy with the results. Most logo's and colors survived. I noticed that an AOpen 48x12x50 CDRW can't handle brake cleaner (I love brake cleaner for cleaning things) very well because the letters started to disappear. Logo's on the Compaq including the powerbutton print survived the whole process just fine. Also the Hyundai logo made it through 100% 😀.
