Keyboards get dirty fast. Crumbs from desk lunches, dust and hair slip between the keys and can make them sticky or unresponsive. Cleaning a keyboard is easy, but doing it the wrong way can damage it. Here's how to do it safely.

Before You Start

How to Clean a Keyboard Step by Step

1. Tip it and tap it

Turn the keyboard upside down over a trash can and gently tap the back. A lot of loose crumbs will fall out. For a laptop, hold it open at an angle and tap the bottom lightly.

2. Vacuum between the keys

Use a small handheld vacuum with a soft brush nozzle. The bristles loosen dust between the keys while the suction pulls it away instead of pushing it deeper. Go row by row.

3. Clean the gaps with a soft brush

For anything left, use a clean, soft paintbrush or makeup brush to sweep around the keys, then vacuum again.

4. Wipe the keys

Lightly dampen a microfiber cloth with isopropyl alcohol (70% or higher) and wipe the tops of the keys. Never spray directly on the keyboard. Let it dry completely before turning it back on.

5. Don't forget the surroundings

Vacuum your desk, mouse pad and the area around your monitor. Dust from these spots ends up back in your keyboard.

Vacuum vs. Compressed Air

Compressed air is popular, but it blows dust around and can push debris deeper under the keys. A vacuum with a brush nozzle removes the dirt instead of moving it. Many people use both: air to loosen, vacuum to collect.

How Often Should You Clean Your Keyboard?

Keeping a small vacuum in your desk drawer makes the weekly clean take less than a minute.
