    Have managed to scored a few PC-Engines, Core Grafx and Core Grafx II systems, the white PC-Engines were very yellowed so i used some 35% strength hydroperoxide mixed with water in a washing up bowl to bring back the white goodness!!.....

    And after 48hrs after.....

    Thats quiet a transfomation!!

    Now the thing was the last few days there hasnt been a massive amount of direct sunshine, and its been very overcast, so it would appear that this method doesnt really need to have the sun to work just basic daylight UV!

    While this method works excellent with white coloured systems, what would it do to the grey shell of the Core Grafx based systems??, as some of them appeared to be stained slightly. Would putting these grey shells in to the hydroperoxide mix de-colour the grey shell, as with the white shells not only did it bring the white back but it also removed stains on the shell as well??

    Wow, that IS quite a transformation. Did the solution destroy the serial # sticker or did you remove that yourself?

    Hot hydrogen peroxide bath can dissolve paper and glue, yeah. But if OP wants to put the sticker back for some reason it's really easy because it's just a glued piece of paper with serial number printed using common font. All you need is laser printer.

    Yeah the label partially came off, so i just removed it.

    An ideas on what Hydoperoxide would do to the grey shell of a core grafx?, it didnt seem to effect the red PC-Engine logo at all

    I don't think it affect the grey, they way you're doing it. Is not HP direct to the shell.

    It might make the core grafix go washed out grey colour .

    How much time did you leave them out to whiten them that much? How often did you change the solution during the process?
