@ Eclipse
If I could secure a supply of H2O2, neat TAED and xanthan gum that would sell to me, I would. I could supply a kit of the liquid H2O2, along with the powdered TAED and xanthan gum mixture to be added and mixed just before use. (I'm writing this concept here, just in case someone else has the cute idea of beating me to it; just don't, OK? If I find out someone does, I may sue your arse to the ground, LOL). |

Thanks Graham, much appreciated; not just by me, but by all who have contributed to this project.

My silly remarks aside I've been quietly following this thread with much interest. Having looked @ Merlin's latest photos all I can say is:
Damn me that's one hell of a result! I'm very keen on the idea of a gel-preparation & am pleasantly surprised to see the foaming effect doesn't seem to have caused any patchiness. @Merlin: Do you think this is 'it'? I'm wondering if for further 'user-friendliness' some kind of anti-foaming agent might be added... ...stuff that's added to some carpet cleaners..? Props to everyone who's come up with this stuff. Oh, and thanks for making the thread as sticky, Graham. |

@ Charlie
The ideal would be to do away with the 'Oxy' and use neat TAED, although I don't think that the average Joe can buy this chemical. This wouldn't foam anywhere near as much and should make for a more placid gel, although it may still foam a bit as the gel won't release air that quickly. TAED isn't soluble in water above 1.5 grammes per litre, so you wouldn't need much. TAED is added to a lot of laundry detergents these days besides the 'Oxy' products and the market for the supply will be dominated by people like Proctor & Gamble etc., so use for such a niche application like this probably won't get a sniff. The main reason I did such an extreme test was to firstly silence the critics from other forums (fora?), that said that this was all bullcrap and that the science didn't hold up; you can reproduce the test I did at home yourself, so there's no need for bluffing, and I can explain the science behind this as required, should anyone care to ask. The second reason was to establish some sort of guide, as to how long it would take to reverse a certain degree of yellowing; I think we've established that most cases would be reversed within eight hours by use of the gel if you use 35% H2O2. If you use weaker H2O2 then it may take a little longer, but hey, 23 years of yellow reversed in 8 hours or so? That has to satisfy those people with short spans of attention.... Adding an antifoam is a nice idea, but may have a counter-productive effect. I've worked on antifoams for various processes over the years, and they are always insoluble in the medium into which they are added and may also contain insoluble particles, so that the Gibbs - Marangoni / Contact Angle effect kicks in (the disruption of surface tension, thus releasing the air from the liquid. This is serious antifoam theory and I could be here for weeks explaining these...I suggest you Wiki them first). The downside of this is that the antifoam may create an effect known as striation or 'fish-eye', the effect you see in hammer-finish paints, and we definitely don't want that on the parts being treated. The best way to reduce foam is to keep detergents to a minimum which is what we have done thus far. Good question though... science abuse rules, and not one caravan was harmed during this project!!!

Man that C64 rocks!!! Merlin you ought to really sell the entire kit (gel and lamp) along with a nice instruction page. If you want a nice vectored Retro Brite logo just let me know ok?
Someone ought to contact Retro Magazine or the retro section of Edge about this methinks... |

No one is selling it *just yet*. I expect they might be in the near future. 35% H202 is dangerous stuff so i'm not sure on the permits and so on you may need to sell it. I wont be selling it but i'm sure someone will look into it.

@ tonyyeb
To be honest, 35% H2O2 isn't required; you can get 20% strength from 'Sally' and that will be sufficient for most people and will offer more control of the process. I certainly won't be selling any kits as there is too much liability attached for my liking. @ Akira Here's the formula, you lazy git, LOL Ingredients:- 1 pint Hydrogen Peroxide, at least 20% strength 1 teaspoonful xanthan gum (health food shops or Ebay) 1/2 teaspoonful 'Vanish Oxy Action Plus' (any 'Oxy' laundry booster will do) 1 teaspoonful glycerine Equipment:- Gloves and Goggles (Safety First!) 1 UV lamp Liquidiser or hand blender Chuck all ingredients except the Oxy into a container and mix until a smooth thick gel is formed. Just before you use it, add the Oxy in by stirring and then brush the mix onto the item to be treated. Stick it under the UV lamp and check regularly until the yellowing has gone. Oh, and please take photos so we can see the results... |

I hate potatos and shirts

As a matter of fact, the "blondie" peroxide (who have some vaseline mixed in) mixed with TAED don't get spent as time passes like pure H²O².
Another hint for you guys and gals. |

What affect does this process have on an aluminium decal? Should it be removed or masked first?
