Personally I would rather live with the authentic patina on my computer hardware than deal with the streaks and faded text of retr0brite use.

Keep me busy this weekend! In between blowing power supplies and running all my cases through a bath of retr0bright! Hah!

Check out the retrobright process too! I've been running through all my cases, printers, keyboards, etc and it's been working like a charm.

RetrOBright is a homemade concoction that's supposes[sic] to restore yellowed white plastic.

If you have or know of someone that has used the Retr0Bright whitening paste on 60s and 70s EM posts that are heavily yellowed, without damage to the posts?
2011 June 9, JC, “Re: Q: playfield plastic whitening with Retr0Bright”, in rec.games.pinball[6] (Usenet):
The retrobright process was developed for use on ABS plastic. Bromine was added to ABS for fire resistance but also caused the yellowing over time.

RetroBright does NOT work on Clear Plastics.

I've been meaning to try the retrobright on some old dolls my Mother has, but I haven't had the time.
2011 July 28, jon allison, “Re: retr0bright and ramps”, in rec.games.pinball[9] (Usenet):
I tried doing some retr0bright on some white 60's EM pop bumper bodies. I left the stuff on for almost a day and it never did anything. It obviously works on the 80's plastics for computers but not the older stuff and possibly not the newer stuff.
2011 November 8, Frank Furhter [username], “Re: Score reels on old EM games”, in rec.games.pinball[10] (Usenet):
There needs to be a chemical in the plastic which the retr0bright solution reacts and effectively 'reverses' the yellowing.

Haven't tried it myself, but it sounds as though you need to mix up a batch of Retr0bright: […]
2012 March 9, JC, “Re: Cleaning my routed STTNG - how to restore the ships?”, in rec.games.pinball[12] (Usenet):
retr0bright works well but the plastic does indeed need to be ABS.

When I got my platinum iie, it had around 18 dead keys and it took hours of work for me to fix it, not to mention using retr0brite on the keycaps.
2014 February 19, Polymorph, “Re: How to Clean and Apple II case?”, in comp.sys.apple2[14] (Usenet):
Whilst I only applied retro brite to one of my IIgs' about 6 months ago (using Tezza's recipe), I have since read on the retro brite forums of people (including Tezza of YouTube fame) experiencing the yellow returning to their vintage equipment after a few years.
2014 February 19, osgeld, “Re: How to Clean and Apple II case?”, in comp.sys.apple2[15] (Usenet):
yep, the reason the case yellows in the first place is still in the plastic (fire retardant) retrobrite can only go so deep, so you keep doing it or seal it up with some UV protective clear coat.
2014 February 19, drk...@gmail.com, “Re: How to Clean and Apple II case?”, in comp.sys.apple2[16] (Usenet):
I never bought into the retrobright thing. Peroxide is extremely corrosive and no one has adequately demostrated[sic] that it is safe for the long haul.
2014 July 3, James, “Re: IIc Teardown”, in comp.sys.apple2[17] (Usenet):
Will have to give that a try...Got another IIc That needs a retrobright treatment.
2017 June 2, groink_hi, “Re: News on Retrobrite / Retr0brite (?)”, in comp.sys.apple2[18] (Usenet):
And, the retr0brite only reverses the process, not eliminate what caused the yellowing in the first place.
2017 August 14, James, “Re: Call for Apple IIgs serial numbers!”, in comp.sys.apple2[19] (Usenet):
Anyone know if use of retr0bright could damage the signature?
2020, Greg Farrell, Game Boy Modding: A Beginner's Guide to Game Boy Mods, Collecting, History, and More!, page 51:
If you want to try this method, you can find Retr0bright recipes and instructions online.
2021, Jamie Lendino, Faster Than Light: The Atari ST and the 16-Bit Revolution, page 269:
Commonly called Retrobright (or, more properly, Retr0bright), it's a chemical formulation and step-by-step process you can apply to old hardware to remove the yellow effect and bring out the plastic's natural coloring.
Verb: "(computing) to remove yellowing from ABS plastic computer or electronics cases via this method"[edit]

These are four different machines I've been restoring over time (cleaning, retrobrighting all the cases, new capacitors on cards and motherboards as well as replacing power supplies but keeping the original chassis to hide the modifications).
2017 June 28, cb meeks, “Re: Yet another IIc in my collection”, in comp.sys.apple2[21] (Usenet):
This IIc is cleaning up really nice. Going to Retrobright it soon!

Do you need to retrobright your machine if it has some yellowing?
