The technique looks very useful at returning things to their original colours; however I would advise caution before you go dunking all your kit.

I think there is at least a possibility that this treatment might damage the plastic long term. I say it's better to have slightly yellow now, than completely crumbled next month.

Of course it's possible that I'm just being too cautious ;)

Just as it bleaches my transformers or Lego. amazing what wannabee blondes and nerds have in common.
