John Tooker has put up an excellent guide to taking care of the yellowing of your white Lego brick utilizing hydrogen peroxide and a dash of the ever famous Oxy-clean. It is a problem that has plagued Lego modelers and old computer equipment collectors for decades, over time and with light exposure, this stuff starts looking gross.

Quick Steps

  • Put pieces into a plastic/glass tub
  • Lightly dust pieces with Oxy-clean
  • Submerge pieces in hydrogen peroxide (3% strength)
  • Place in sunlight (optional)
  • Once a day, add peroxide, stir if needed
  • Rinse on the 5th day, or when white enough
