This reminds me of my plastic rectangular ramen bowl. And for the same reason, it drives me nuts! It’s full of text that, with normal expected use, will be covered/inundated with fooodstuffs, and ain’t nobody got time to get into all those little crevices with a toothbrush to keep it clean.
edit: speaking of, I should either throw away my ramen bowl, or take my dremel and polishing files to it to try and salvage the situation.
