aha, thanks. Sorry to be needy, but is that the same for all types of keys including the graphics printed on the front of C128 keys in light grey?

It's OK mate; black lettered keys will definitely be laser etched and will survive the process, the white lettered keys are more likely to have been screen printed. You may see some feathering of the edges of the letters, however, they should survive. Keeping the peroxide strength on the low side is definitely the way to go with white lettered keys.

@ All
I've updated the Wiki with some more explanation in the UV Energy part, so that you can start to understand why the UV is so important and how it works. I've tried to make this easy reading with words and pictures. |

@ Chiark
Can you please e-mail me the photos of your original tests? The links earlier in the thread are now broken and I would like to add your tests to the Gallery section of the Wiki. I've started adding some photos already, please let me know what you think. |

Here's the C128 test
http://eab.abime.net/album.php?albumid=147 From: To: So, yeah, I'd say it works. For me, sunlight is the magic ingredient: stronger the better... As mentioned, getting it mechanically clean is, I believe, very important. I used a dishwasher but removed the case before the drying cycle. I used a paste made from arrowroot for both the case and the keyboard, and used 9% - however I did dilute it for the second pass of the case, and that was the most effective (sun was strongest, temp was warmest) One point: there was a mark on the case from a coffee cup which had dented the plastic. After coming out of the dishwasher, this was bright white: it's still whiter than the rest of the case. Last edited by chiark; 28 February 2009 at 22:07. |

Nice one jailer.. good to see you've had positive results
To all - I've been 'whitening' again this weekend with a combination of slightly diluted peroxide cream combined with some Oxy and limited sunshine. The oxy (half teaspoon) was tipped straight into the cream (approx 250ml) which resulted in a nice sticky / foamy paste. Fantastic results so far. Merlin notes on his Wiki that strong peroxide alone results in the platic 'blooming'. He is correct; as my attempt last week left my Vic cart with a white but dull finish. The weaker mix with oxy seems to retain the sheen of the plastic. As a side note, the mix also whitens grout on ceramic tiles and cleans faded white gloss paint up nicely...nothing is safe anymore!! Be careful, Magno |

I have to try this myself, the pictures look so good
I can find Hydrogen Peroxide and glycerine easily -- but here in Finland we don't have products called "Xanthan Gum" or "Vanish Oxy Action". Please could you Merlin (or anyone else?) provide me with a list of chemicals/ingredients the stuff I have to buy should include? Any chemicals they should *not* include? I'm going to the local store but first I want to know what to look for... Thanks |

@Andymiga, if you're in Helsinki, I could probably bring some over...

Check out the Wiki, there are pictures of the ingredients used in the section about making the gel. http://Retr0bright.wikispaces.com |

The problem is that I have absolutely no clue what would be similar to this Xantham Gum stuff ... all other ingredients can be easily found (I think ) Thanks, or I could come over and pick some up. I'll send you a pm |

Xanthan gum is a starchy food thickener. You may find it along with Corn starch (cornflour), arrow root and other starch based thickeners in the bread ingredients section of your local supermarket. Xanthan gum is sold for use in making bread for people with an allergy to gluten. Alternatively, a health food shop might be able to help you.
Wallpaper paste should work as well; all you are using it for is to thicken the mixture and make it paintable onto the surface. /Merlin waits for Customs to kick Zetr0's front door in, for sending little packets of white powder to Finland... |

I found a lot of information about XG as an ingredient in several foods, but couldn't find it separately... I'll see what the local big supermarket has on the shelf Quote:
edit: I misread your post Merlin. So does it have to be Xanthan Gum especially, or can I use corn starch??? Thanks, I want to be sure about this Last edited by Andymiga; 02 March 2009 at 15:27. |

A couple of linkies for you.
http://www.healthstore.uk.com/p44443...-Gum-115g.html http://www.goodnessdirect.co.uk/cgi-...Gum__100g.html http://cgi.ebay.co.uk/Doves-Farm-Xan...216112002r9327 Doves Farm and Life Free are the two main brands in supermarkets in the UK. Larger Asda and Tesco branches stock it. I just used XG as I have worked with it in the past and I knew it would give me the properties I needed. There's nothing wrong with a 'variation on a theme' though; if you find a thickener that works for you, let me know and I'll add it to the Wiki. |

@ All
Just to re-iterate the point above, the recipes in the Wiki are a guide, that's all. If you use the ingredients as listed in the Wiki we know what the results will be. I am 100% sure that other starchy, inert food thickeners will work, it's just that they probably haven't been tried yet. They will be safe to try in peroxide solutions as they won't react with it, that's why I went down this route during the development of the gel. If you do find something else that can be used to make a paste or gel, please post pictures along with the recipe you used and I will add it to the Wiki. |

Arrowroot = nuolijuuri, apparently . Found in well equipped grocery stores, health food stores, or ethnic food stores.
By "bring some over", I meant from the UK next time I'm in Helsinki |
