This weekend I bought some hydrogen peroxide gel from a local store.
And started to retrobight the top covers of an Amiga 1200, C128 and a vic 20.
First I cleaned the case parts very good with a toothbrush so all dirt is gone.
Then I used a brush to “paint” the case parts with the gel, and wrap them in with plastic foil.
After this I left them for some hours in the garden.
It was a warm day, but the sun did not burn as there were a lot of clouds.
After some hours I cleaned the gel from the cases and was surprised by the result.
I will do it another time as I noticed I missed some spots.
And then I will also do the bottom part of the case.
