@ all
The best recipe is this:-
1 pint (500ml) 10 to 15% Hydrogen Peroxide solution (do not use stronger than 15%, as low as 6% has been proven to work)
1 tablespoonful (10g) of Corn Flour, Xanthan Gum or Arrowroot (any starchy food thickener will do)
1 teaspoonful (5ml) of Glycerine (it helps the thickener disperse and wet out better)
1/4 teaspoonful (1.5g) "Oxy" laundry booster
You should be able to get these materials easily.
Blend the first three items for 30 seconds with a high speed hand blender or liquidiser. Let the mixture rest and 5 minutes later you should have a thick almost clear gel which won't drip from a spoon. This is stable and can be stored. DO NOT add any "Oxy" until you are ready to use it.
Add the 1/4 teaspoonful of "Oxy" and stir it in with a spoon just before you brush it onto the item to be treated. Stick it under a black light or sunlight and check periodically. Once you are satisfied that the colour has been restored, wash all traces of the gel off and allow to dry. Coat with a clear lacquer to seal the oxygen away from the surface and it should stay the restored colour indefinitely.
