Any help for fixing stained plastic/sticker vinyl?

[attendu]

I have a few cubes that out of nowhere ended up getting damaged sitting on my shelf face down. They’ve gotten these weird stains on the plastic as well as the stickers for one of the cubes and I have no clue how they got there. Any ideas on how to remove them? I tried all purpose cleaner with bleach in it and it didn’t do anything, I’m pretty stumped with my options at this point.

I have encountered the same issue as well. What I do is to simply order replacement parts online.

Did you ever figure out what was causing the issue in the first place?

I don’t know how this happens, but I have done something to avoid such damage to my wca mains as the replacement parts are not that cheap. I have bought 5 yj cube bags where each of them can have 3 puzzles in it. This is the only cube bag out there that have protective cushions inside. I found them very convenient and doing their job well so far. Obviously, you are not going to put few megaminxes or 7x7s together as they won’t fit in that way. I put 2 skewbs together with a square-1, 2 magaminxes with a pyraminx, 3 3x3s together, 2 2x2s with a 7x7, and put 4x4 5x5 6x6 together. Clock can be put separately in another simple cube bag.

This is useful, I can finally prevent my puzzles from being covered in pencil marks and scratches.
