Lift the keyboard upside down and gently tap/shake to remove loose debris. For a more thorough clean, disconnect your keyboard from the computer Take note of the keys’ location, and remove using a tight grip with your finger, or a blunt knife to gently wedge the key cap out, careful not to damage the key cap or the keyboard underneath. Wipe each key down with isopropyl alcohol and vacuum your now keyless keyboard. For an even deeper clean, grab a cotton swab dipped in isopropyl alcohol and clean inside the keyboard remembering to be gentle. Give it a minute to evaporate and replace all key caps back in their correct spot.
Start with the mouse by unplugging it from your computer as well. Grab an alcohol wipe and thoroughly wipe the mouse and using another cotton swab in isopropyl alcohol again, do a deeper clean of the middle button, and any other buttons your mouse has.
Re-plug everything back in and you’re done!
