Messy Desk Secrets

So I work from home as a freelancer and my desk has become this bizarre monument to chaos. Yesterday, while looking for something under a pile of papers, I accidentally knocked over my water bottle, which leaked everywhere. To make it worse, the paper towels I grabbed were wet too, so I ended up making everything even messier. Now, I've got stains and water marks all over my laptop keyboard and no idea how to clean it without damaging anything. Talk about a productivity killer.
