Wipe It Down

Grab a microfiber cloth and dampen it with a bit of water and a tiny bit of distilled dish soap—you want enough that you can see there’s water streaking across, but not too much that you’re drowning the board in liquid.
Run the dampened cloth across your board, the keycaps, and any nooks and crannies that might need a personal touch. Then, dry it off with another microfiber cloth. Avoid paper towels as they can shred into the board. They’re also slightly textured, which can introduce scratches and nicks to your keyboard and caps.
