Hey folks, You probably all know this but I wanted to report success in restoring some old Focus 2001 mechanical keyboards... I've had these around since the BBS era, and they were quite yellowed (and pretty disgusting otherwise too.. :( ).. Anyway, after doing some research -- Salon Care 40 Volume Creme is basically "retrobright" in a bottle. $5 for 32 oz, and I still have a lot left over (next case to restore = Amiga 1200). Attached pic shows basically a before and after (two different keyboards, but both were equally as bad). A few things I learned: - 4 hours of sunlight (UV) is enough, 6 hours with clouds is just enough with the solution - Use cling wrap over top of any plastic you've applied the solution to to keep it wet -Soaking the keycaps in dish soap and hot water for a few hours does wonders, then: - You can be a little lazy with keys by putting them in a glass bowl, pouring 3% hydrogen peroxide over everything, and putting aluminum foil underneath to make sure UV bounces everywhere. With this method you'll probably need a second bath or manual application of the creme to restore all keys properly. - I used a lot of q-tips and 90% rubbing alcohol to clean the keyboard and electronics internals - Of course wear gloves with this stuff - Using a keyboard with an XT/AT switch on a modern PC is fun :)
