#1570 TIPS: Yellowed LEGO bricks – Prevention and Usage

Ah yellowed bricks, hated by many and loved by some. In today's post we deep dive into the topic: why does discolouration happen, how to bring the colour back and how to use the yellowing to your advantage!

Editor’s note:

- we want to correct a statement on slide 6: moisture or humidity will NOT cause yellowing. Thanks @stlbrickco for pointing this out.
