[Coco] retrobright

[Gabriel Holland]

I've used it on a CoCo2 as well as a few Commodore computers and I have had good results.  Sometimes you have to do more than one application.  Sometimes you get streaks.

http://www.retr0bright.com/make.html
1 pint (500ml) Hydrogen Peroxide, 10 to 15% strength (40 vol) (available from hairdressers' supplies, e.g. the 'Sally Beauty' franchise in the UK)
2 heaped tablespoonfuls of Xanthan Gum (available from health food shops or online)
1 level teaspoonful of Glycerine (available from pharmacies)
1/4 teaspoonful of "Oxy" laundry booster


Wrap the mess up in saran wrap and leave it in the sun for several hours.

There are many variants - such as only using the peroxide, UV lamps in stead of the sun, or no UV at all.
