^Quick tech tip: If your keyboard, screen, TV, phone, needs to be cleaned, get the strongest % rubbing alcohol and the gentlest cloth/paper towel/toilet paper you got. Just a tiny bit of rubbing alcohol goes a long way.
Just used 91% rubbing alcohol (on a paper towel – just a few drops of the stuff) on my laptop keyboard and screen and mouse and it's a lot nicer to use now.
It's a simple trick but easy to forget. Rub lightly too; just in case a piece of real dirt gets stuck on the cloth and scratches stuff.^
