Any Aussie Amigans managed to make up some RetroBrite?

Hi,

After reading a few posts about people skipping the addition of Oxy altogether, I had another go today...

I've tried using just the Creme Developer and I didn't see any of the 'blooming' I had when using the Oxy added. I did my first 'test-run' yesterday (and an A3000 mouse) and I ended up with some white spots on the buttons and an overall 'blotchy' or uneven removal of the yellowing...

Today I tried it (no Oxy this time) on an old VIC-1515 printer. I was using a 40vol (12%) Creme Developer and brushed it on with a small (about 1/2 inch across) artists brush, reapplying/rebrushing every 45-60 mins.

However I seem to have the same issue as yesterday, with uneven removal of the yellowing. The brush-marks of the initial application were still quite noticeable, even after 6 hours outside in the sun.

Do you have any other suggestions on what I could try for a more even finish?

Possibly diluting the Creme Developer with distilled water?

I've heard some people use a much weaker (3%) solution (plus Oxy) with good results.

I'd like to get it down pat before I risk the front-panel of my A3000! :-)

Cheers,

Mike.

Complete submersion in the solution is the answer to even lightening.  I've diluted 12% liquid peroxide 50/50 with plain old tap water (to submerge larger items without needing gallons of H2O2) and used various items to help displace the liquid as well.  Making sure the items being lightened stay completely submerged is also important.  I've also never had to use any Oxy product.

Never had this patchy result and i used the 250 ml 12 % peroxide with a level teaspoon of oxy dissolved in a small amount of tap water, mixed it all up, which I then brushed on every 1-2 hrs as it dried out.  I wonder if the cheap oxy power is to blame?  You do not want anything with chlorine in it, I wonder if your "oxy" has chlorine in it?  I used Sards with Oxy and White King with oxy on different times, and no streaks or spots, whatsoever.  

There's an explanation on the chemistry as to why oxy is necessary on EAB.

What Stefcec2 wrote. I use the same blond hair developer cream in Bananaland and it is OK for Retr0bright.

 Just watch the concentration: it must says "30 volumes" or less.

Goodbye people.

Was an honour and a pleasure to be in your company.

I'll miss you.

Why ?  Where are you going ?

Hmm...

I might try again with some of the proper Oxy stuff and also experiment with some 3% solution...

I'm using the recommended 40vol (12%) - is this too strong (30vol or LESS has been mentioned)?

This is not as magical a solution as I expected! :-/

Let us know how you go.  Filling a tub to submerge a whole case is gonna take a bit.
But if the brushing doesn't work that might be the only option.

Its possible that it dried out for long enough in places, resulting in localised areas of very high peroxide concentrations and the patchy bloom.  Maybe rewetting/reapplying more frequently?  Several of us have applied 12% peroxide with a bit of oxy with a brush without streaking or blooming.
3% peoxide will take a very long time, according to the folks at EAB.
