Years of exposure to sunlight and other UV can result in yellowing or even
browning of Apple II cases. One solution is to pick a color and paint the case
via a few light coats of a spray paint. If you want to restore the original
color, you can get a good match using Apple II pictures available on the net.
A recently discovered alternative to painting is bleaching out the
discoloration using hydrogen peroxide (H2O2). According to claims, the process
described here does not damage painted labels, metal inserts, etc. except as
they may be attached by a water soluable adhesive.

What You Need
- Hydrogen peroxide (H2O2)- water added as necessary to get desired
concentration
- Vanish Oxy Action or Oxi Clean Versatile Stain Remover or pure
TAED (Tetra Acetyl Ethylene Diamine)-- don't need much
- UV 'Blacklight' bulb (60 watts or so) in a lamp (indoors) or sunlight
Note: Do not use other UV sources, such as germicidal lights.
- Plastic or glass container (possibly with a transparent cover)
- Bostik Blu-Tack or similar reusable adhesive to help hold small parts in
position
- Water close by, such as in a large bowl, for washup and washing off cleaned
parts
- Rubber gloves
- Full Protection Goggles. You only get one pair of eyes!
- Tongs may be helpful for retrieving smaller parts
WARNING: Do Not even think about mixing in chlorine bleach with the H2O2!
The result could be to release chlorine gas.
Hydrogen Peroxide Mixture
Hydrogen peroxide(H2O2) comes in two well-known forms: stable and unstable
(rocket fuel) determined mainly by concentration. The highest concentration
which is commonly available and which is allowed for postal shipping is 35%.
H2O2 in useful strengths is available in various forms and concentrations from
several sources including chemical sellers, cleaner makers, and hair product
sellers.
