I like to clean my laptop with coffee at least once a year.

To accomplish this: make a cup of coffee and enjoy as you normally would.

Then, absentmindedly set it down near your laptop and then shortly after.. absentmindedly reach for it.

Once the coffee is spread evenly over the laptop.. as panicked as possible.. run for paper towels and wipe it down as best you can.

Repeat approximately every 12 months or as desired.
