Also, we have to have 'before' and 'after' pictures of your tests, we likes our pr0n we does...

@ PalKat

Nice one! I look forward to my piccies..

@ Zetr0

Nope, I am hopelessly addicted mate. Nice synopsis by the way, well presented and it captured everything we had talked about and theorised, I just hope that there are others that understand it and don't think we are talking "Wizard-speak"....PMSL!!

@ all

Seriously, we felt that explaining the theory was necessary not only to educate people (and pose about some of the little-used expertise available out there, that occasionally does AWESOME ((c) Zetr0 ) things), it was also to justify why we are using this method against using bleach and other chemicals. We also got trolled about this on some other forums, which is why we have stated the science behind it, this process has logic and a proveable scientific basis to it.

We feel that we have managed to create a safe and reproduceable process that allows members to restore their plastic items to near new condition and we have released it for all, that's what being part of the scene is all about; it's about doing your bit....whatever your skill is.....

The gel version of our magic brew works!! Lorne over at VCF added some xanthan gum to our magic brew and tested it on a panel, photos are here at the end of the thread:-

Yes, I know these are long threads, but this reflects the interest and amount of work being put into our discovery.

Fan-tastic!!!

@merlin, your link is only visible to members of that forum. Thanks though.

@ DDNI

Sorry, I didn't realise....

If you add 1/4 to 1/2 tsp of xanthan gum to our mixture and disperse if with a hand blender, liquidiser or similar, you end up with a foamy gel.

Brush this onto the component and zap it with UV as usual. After 6 to 8 hours you should get a similar result to immersing the component, however, you have used a lot less liquid and saved a bundle of drinking vouchers. For large areas this is the way to go.

Lorne had to apply the mixture 2 or 3 times at his end, but that was because it's so hot where he lives in Arizona and the mixture was drying out. In cooler conditions, one coat may be all that you need.

Result!!

[DDNI]

Nice. Xanthan gum is available widely?

[Merlin]

Yes, it should be widely available from health food shops or there are loads of sources for it on Fleabay. I wouldn't be using any ingredient if it wasn't easy to get hold by Joe Public.

As an alternative, I believe wallpaper paste, hydroxy ethyl cellulose (Cellosize), starch or even cornflour (corn starch) may have a similar effect; the key thing is that it should be inert and not react with the process.

Perhaps someone may want to try some of these as the gelling agent and let us know if they work....?

What % of H202 are you using then?

[Merlin]

You should be able to get 20% H2O2 easily from 'Sally' hairdressing trade suppliers, as it is used to bleach hair. You will also find up to 35% strength used in swimming pool chemicals and as a pet urine neutraliser in kennels. Lorne found it as something called "Urine Rescue".

Lorne used 35% but 20% would give the same effect. Weaker solutions just take a bit longer, that's all.

[Merlin]

Hey guys,

We need a name for this concoction we have invented between us. Does anyone have any suggestions for a name?

I was also asked on VCF about patenting it; since we have released it to all, I don't know if that would be possible now, unless the posts on the various forums count as prior art and proof of concept; I'm not that bothered anyway.

[twizzle]

how about

MERLIN`S
PLASTIC`S WHITENER

and as for patenting it, you have to create your invention ( done) and maybe fine tune it.
then have it tested ( by the people on this site )
you havent let it out to jo public as such? so its still contained within eab.

so go for it.

[Zetr0]

@Merlicious

you cannot patent what is now in the public domain, HOWEVER, you could register a more agressive formula say 50% + TAED + differnt Gelling Agent you could patent it.

anyway more fun would be in the naming....

hmmmm

VP-Reviva-Gel (Vintage Plastic Revival Gel)

I've heard that using aluminium powder with Iron oxide (rust) powder and heating it does wonders for Atari ST's.
