I don’t know who needs to hear this, but stop what you’re doing and clean the device on which you’re reading this. Get some compressed air, a microfiber cloth, whatever (mine was truly filthy so I used a microfiber cloth, wet and well wrung-out, along with some glasses-cleaning wipes for the screen and alcohol pads for the truly disgusting parts of the keyboard), take the protective case off if you have one and just really get in there. I’ll wait.
Ahhh, isn’t that better? I feel like I have a whole new computer. Sometimes a fresh start is all you need.
