i spilled a drink on my computer keyboard

No and no. If they're sticky to the touch, you can assume safely they are sticky underneath too. You can wipe the key tops with a slightly dampened soft cloth, but that's not going to fix a real problem. Liquid spills on the KB usually get inside the Mac.

You need to have Apple look at it. Some juices are quite acidic and are therefore quite corrosive. All are sugary and that's not good either. Either way, you can read all sorts of home remedy suggestions, but ultimately Apple needs to evaluate it.

Hello quinn107, This has happened to me too in the past and I wound up buying new keyboard. I also bought one of those keyboard covers that protect keyboard from liquid spills. Just do an internet search for Keyboard Protector to find the right size for your keyboard. It is a lot cheaper than a new keyboard.

Before you use a keyboard cover, read what Apple says about using them:
