Edit: This is a repost of an article we published in 2015 but is now applicable more than ever in the wake of the global Covid-19 pandemic. We have received multiple calls this week from customers who have tried to sanitize their laptops (kudos) and ended up liquid damaging their keyboards or, worse, the motherboards in their laptops.
You’ve heard how your smartphone is a breeding ground for germs and bacteria. Guess what, your laptop keyboard is probably worse. With their many cracks and crevices and peoples’ uncertainty as how best to keep a much used laptop keyboard clean, most users may never have cleaned their keyboard. Today, I will let you know how.
The first step is to get rid of any buildup along the sides/edges of the keys. You can use an old toothbrush to freely brush up & down and sideways, concentrating on the areas between the keys. The bigger (taller) the keys are, the more brushing (horizontally & laterally) required.
After this, use a vacuum with a brush attachment (to avoid scratching the keys), moving up & down and side to side.
Finally, use a paper towel or lint-free cloth soaked with isopropyl alcohol (70%) wringed out enough so that there is no more liquid dripping from it to wipe back and forth. Make sure to squeeze out as mush excess alcohol as possible before wiping the keyboard. Any excess liquid dripping onto the keyboard may cause permanent damage.
