RetrObrite

[ezcomputers]

Hey just wanted to post my progress... I have a IIE Platinum that had turned UGLY Brown... well on a longshot since I had nothing but 3% h202 and I looked at Clorox 2 for colors which has h202 in it and other whiteners... Well to my surprise I used some of my 3% h202 to dilute the clorox2.  Used 3/4 clorox 2 25% h202 3% and used a paintbrush to brush it on like a gel.  I put it in the sun and would check on it every hour to reapply the gel all over. Started the process at 1:30pm just brought it in at 4:30 and it WORKED Awesome!  I still need to go another round as one side I didn't have in the sun for long enough and I need a little more time to get it totally whitened to match the parts that are still original color, but its 90% better than it was!!!
I will post pics when its done and though I boneheaded and didnt take them from the very beginning, I have another IIE that is the same nasty yellow this one was... I'm so excited!! So there you have it, if you don't wanna mix a bunch of chemicals try out clorox 2 and some regular old h202 3% from the pharmacy.  The h202 3% contains purified water so i used that to dilute the clorox2 instead of tap water and used it mostly for the water.  Reading the clorox 2 label is has other whiteners in it I'm guessing oxidizers similar to oxyclean?
Anyways just wanted to post my success at trying this
I'd like to know if anyone else has tried using clorox 2 or if you do please let me know. I will post a compelte picture before and during and after when I do my other apple IIe
SOOOO Glad I found this forum

I didn't make any Retrobrite. Just bought 2 liters of 30% peroxide and added 4 liters of water. Check out the results:

My Elbox front plate came out the original color.

Does anyone know if there is a way to buy these ready mixed?

Yes you can get it ready to go, it's called Clairon Professional 40 Creme Developer.  It's a milky white creme that works great, been doing it to a bunch of C= and Atari stuff and works great!

40 Creme Developer isn't as aggressive, I found some version to contain 12% of H2O2.

the cream is no good if you plan for direct sunlight exposure.


the clear kind is good though submerge it in a fish tank and stick it in the driveway.

the 40 developer creme ie 12 % peroxide works GREAT if you add a pinch of washing powder that has oxy in it (dissolve it in a bit of water).  this way you don't need to buy a fish tank, just a small artists paint brush to brush it on with, and for the keys just add a bit more water (distilled is better) to cover them in a jar, leave the top open.

Dryout is a pain and can cause uneven lightening.  Everyone should have a big vat of clear peroxide!

..I've gone so far as to pour mine back into the bottles and reuse it months later.

ROTFLMAO! I am literally snorting Hoppalicious Ale Asylum beer right now - the image was too funny!

This thread is great. I'm gonna have to try me some of this peroxide gunk someday. Already did the bleach/oxy/UV thing and it didn't work worth a damn.

Over here it's impossible to get highly concentrated peroxide anywhere, the highest concentration is the 12% creme developer, so if it works we'll just have to make sure we check it often and keep it moist. I've wanted to try this for years, but wasn't sure if this creme developer was strong enough to work. I'm definitely going to buy some, and some Oxy powder next time I can afford it!

That is because our Politicians are Scared some of the population might take to them with Peroxide bombs.

It is along the lines of why the Federal Aviation Authority here in Australia determined we can only have useless plastic knives on planes, instead of metal ones because we might go Postal and kill the flight crew, but still giving METAL forks which can equally cause serious injury when poked in the right places.

Anyway, I digress.

Back to Miggy whiteness

I've had no problems at all!  The reason?  The milky creme developer is thick enough that it does not block the sun.  And it is better than the clear kind that is just too watery and tends to dry up too quick.  Seems the creme is better as it stays on the parts longer.  I imagine if you constantly brushed the regular peroxide on every 5 min that it would work great.  But I rather not do that!

This is the most dramatic item I have done so far.  I did not even dismantle the unit!  I did the keyboard by gently brushing the creme developer on every 30 min or so.  It was thick enough that it did not drip in the keyboard.  I think I left it in the sun around 6 hours.  I then cleaned all the parts with some SimpleGreen and a damp cloth.  On others I did just remove the keyboard and mylar and did it that way, and it was better to clean it up (was really dirty anyhow)

Here's some before and after pics.  I didn't take a before photo of the cases, at the time I was sceptical it would work, but trust me the cases were as yellow as the keys.


Only the case of the A4000 keyboard has been treated.  The keys are from an A500, so i'm nor sure how they're supposed to be, bu the keyboard case was yellow.
