TIL you can fix a sticky keyboard key with a pencil eraser

My buddy Dave at the electronics shop showed me this trick. He said graphite from a soft pencil eraser rubs into the switch mechanism and lubricates it without gumming things up like WD-40. I tried it on my old mechanical board that had a stuck 'A' key for months, and it started working again in like 20 seconds. Anybody else got weird keyboard hacks that actually do the job?

Eight out of ten keyboard problems I see people complain about online are fixed by literally just unplugging it and plugging it back in. Not saying the eraser trick doesn't work, but we might be overthinking a piece of plastic with some dust in it. I'd rather spend 30 seconds blasting the key with compressed air than rubbing a pencil on it and hoping the graphite doesn't get into everything else. Then again, I've seen people throw away whole keyboards over a single stuck key, so maybe a little common sense goes a long way. Honestly, if your 'A' key was stuck for months, that's on you for not trying something simpler first. But hey, if it worked, it worked.

My buddy @the_wyatt had a space bar that was sticking for like two weeks. He tried the pencil trick, tried blowing on it, nothing worked. Finally he just popped the keycap off with a butter knife and found a dried piece of gummy bear stuck under there. Cleaned it with a toothpick and it was fine. The guy was about to order a whole new keyboard on Amazon before I told him to just look under the key. Sometimes it really is just food or dust and not something that needs a science experiment to fix.
