'How to deal with the "not-so-mellow yellow" of old computers and consoles.' Thought this might be of interest to someone here. http://retr0bright.wikispaces.com/ And yes, the URL and the title of the page are spelled differently, who knows why.
Interesting project. However, I would dispute their claim that this was discovered last year. I've known of people experimenting with Hydrogen Peroxide for countering the yellowing for years. The early style C64 was indeed that smoky colour. The later model was white.
Damn, you beat me to posting this Very cool though, I'd really like to try it out on my old Apple hardware.
There was a lot of discussion earlier about using hydrogen peroxide to reverse the yellowing, but it seemed to make the plastic more brittle and fragile. I'd like to try it myself though.
I seem to recall hearing that the "Retrobrite" formula didn't work on SNES yellowing for some reason. Am I just imagining things? Can anyone confirm or refute this?
nobody's bother reading the topic uh? in any case (and in short for lazy people), it depends on the kind of plastic and kind of yellowing.
Seriously, they sell it, I buy it. I may mix some myself, but if I could just buy some, I'd definitely use it.
I did this to a SNES (vid somewhere... too lazy to log into YT and link ) It certainly reduced the yellowing from a VERY yellow to a slightly yellow after a treatment of low% grocery store Hydrogen Peroxide (waste of time, nearly) and then two treatments of 15% bought off the interbutt. I used corn starch as a thickening agent instead of the recommended ingredients, and am not sure if my lighting (which consisted of leaving it under a "black light" as well as a bunch of other lights at night, then the next time outside during a bright day) was up to par. The solution seemed to dry out quicker than I expected. I figure this was due to either the corn starch or my lighting techniques. It was fun, except I did get a small chemical burn on my finger that I thought was just some corn starch residue... but then when it didn't wash off... It didn't burn (hurt), it was more of a weird sesation, almost an itch. So... wear gloves.
as was stated in that topic seriously guys, be careful with chemicals, and ASK (me or around) how to use them safely.
Yes, ask before you do something. The last thing we need is people blinding themselves for the rest of their lives over a C64.
I'll try it first on an iiyama 17'' crt monitor and some old keyboards. If my method/mixture is good, I will clean my dad's Amiga 2000 (and it's peripherals) that way.
