I spilled some juice on it
Ok.I'd suggest cleaning the bottom of the keys, remove the keys and look at a picture of your keyboard and just clean it
Won't it break if I take the keys off? If not how do I even do that lol?
Unplug it and submerge it in water then let it sit upsidedown in the sun for a day. If it's a fancy digital keyboard then you'll have to wait longer.
Turn off sticky keys.
