thought I’d put this out there to see if anyone else experiencing the same issue as me. Firstly I’ll start by saying I’m neurotic about my lego Sets. For this reason I keep them sealed in their boxes when purchased until I can purchase a display case. Once built they go straight in the case and then on display, the case keeping them as dust free as possible. My problem has been of late that I’m noticing slight yellowing to a number of my white pieces, when I’m opening sets to build. The most recent in particular being the Creator Brick Bank. The 1x8 Bricks seemed particularly yellowed compared to the 1x6 bricks and other white parts. The white wall of the building looked awful when completed. Other sets seem to have tile pieces with similar issues, not so bad on their own but when put with other pieces very noticeable! It only appears to be certain parts within a set and not all.
Now, is this some quality control issue at Lego’s end and white pieces are no longer as consistent as they used to be, for example my Sydney Opera House shows no signs of yellowing at all, and that’s even after being on display for nearly 4 years. Or is it in some way how I’m storing the boxes/sets until I build them. I live in the UK, so max temp at the moment prob about 30, and all my lego is kept either in a wardrobe or in my Lego room, which is kept dark with a blind down most times, but can get quite warm especially during the day. Surely white Lego can’t go yellow in a sealed box in UK temperatures or can it??
Just wanted to see other peoples views on white pieces or if anyone else has similar issues. I’m dreading opening my Roller coaster as that’s full of white pieces.
