This is a love letter. So I was eating noodles at my PC (I know, I know) and I poured soysauce over them - only some of it splashed, and went on my screen. Oh no! I tried cleaning it with a cloth and it just smeared everywhere. Then I thought... what would UFYH do? The answer came to me: vinegar! Or alcohol. But I didn't have any alcohol. So I cleaned the soysauce off with vinegar, then dried the vinegar off too. Clean, streak-free screen. Thanks, UFYH!
