  • Step 3: Pick at gunk and swab between keys

Use a toothpick to gently pick out remaining gunk underneath the keycaps and dislodge it. You can also use a straightened paper clip; however, be careful about making permanent scratches when picking. Afterward, prepare a cotton swab, dampened with isopropyl alcohol, and wipe it gently around the edge of the keycaps. This process can remove the dried liquid or grease lingering on the keys.

  • Step 4: Final touch: wiping down

For the final touch, you may use hand wipes, lens wipes, or a dampened cloth with water, to run on the surface of the keyboard. Be careful not to use strong liquid products when cleaning the surface as it can harm the plastic of the board. Use a dry cloth for the final wipe.
