Retrobright (stylized as retr0bright or Retrobrite) is a chemical process used to remove 'yellowing' from acrylonitrile butadiene styrene (ABS) plastics. The original meaning has been expanded, so now "retrobright" often refers to indicate any H2O2 based process used to remove yellowing from ABS plastics. The usage has also expanded to other retro restoration applications, such as classic and collectible sneaker restoration, where it is referred to by collectors as "sole sauce". Yellowing in ABS plastic occurs when it is exposed to UV light or excessive heat, which causes photo-oxidation of polymers that breaks polymer chains and causes the plastic to yellow and become brittle. The method of reversing the yellowed discoloration was first discovered in 2007 in a German retrocomputing forum, before spreading to an English blog where it was further detailed. The process has been continually refined since. More information...
