Clean up those Old Computers with Retrobright


If you are a collector of old computers you are probably bothered by the inevitable yellowing that takes hold on even the most well preserved machines. Now this coloring was due to the inclusion of ABS, which makes the case flame retardant. For a long time it was thought this coloring was irreversible, but no longer. Thanks to the efforts of hobbyists, collectors and scientists – the world now had Retrobright.

    I’ve also found that the Magic Eraser (Mr Clean makes ’em but there’s also generic brands too) works wonders for this stuff. I completely restored my old SNES and Dreamcast that both turned all shades of yellow and orange with just a few minutes of using a slightly damp Magic Eraser. The product is really amazing and one of those ‘too good to be true’ things that really does what it’s supposed to!

    Hi, this is Merlin (yes, THAT one!). I wouldn’t recommend using Magic Erasers as they are like sandpaper and just sand off the surface. Our process, if applied correctly, doesn’t degrade the surface of the plastic at all.

    ABS is the type of plastic the case is made of. The yellowing is caused by Bromine in the fire retardant chemicals mixed into the ABS.
