Dust and crumbs collect between keys, but soaking the surface can let liquid enter the electronics. This guide adapts Microsoft's accessory-care advice for light cleaning of external desktop keyboards. Built-in laptop keyboards and keycap or switch disassembly require model-specific instructions.

1. Read your keyboard's care instructions and disconnect it from the computer. Turn off wireless models and remove batteries if the manual allows. Do not wet-clean a connected device.
2. Turn the keyboard upside down and gently tap out crumbs. Avoid vigorous shaking or prying off keycaps.
3. Remove dust between keys with a manual-approved soft brush, gentle vacuum brush or canned air. Follow the air can's safety directions if used.
4. Lightly dampen a lint-free cloth or cotton swab with water and mild soap. Wipe key surfaces without dripping, and never spray liquid directly onto the keyboard.
5. If disinfection is needed, follow the keyboard maker's approved method. Microsoft permits isopropyl alcohol at 70% or less on a cloth for its accessories, but this does not apply to every brand.
6. Wipe away remaining moisture and let the unit dry thoroughly before reconnecting. Seek manufacturer support for sticking or malfunctioning keys rather than forcing disassembly.
