Your keyboard need regular cleaning to perform well and last longer. Here's the safe way to do it without damaging sensitive components.
Unplug the keyboard (or turn off wireless). Turn it upside down and shake gently to dislodge loose crumbs and debris.
Use compressed air in short bursts at an angle between the keys. This removes dust and particles trapped under the keycaps.
Dip a cotton swab in 70% isopropyl alcohol and clean between and around each key. The alcohol disinfects and evaporates quickly.
Dampen a microfiber cloth with isopropyl alcohol and wipe all keycap surfaces. This removes oils, grime, and sanitizes the keyboard.
