I have made it a habit of cleaning out the various areas in both my desktops and laptops on a monthly basis.

When i was running a computer repair shop back in the day i would make sure before the customer picked up the computer that it had been given a good cleaning.
Then when it was picked up i would give the customer a few quick pointers on how to keep it clean, and also provided a few cleaning products for free.

i found a happy customer would get me more customer's, and they would also come back in the future..

and i also agree the product manuals these days are pretty crappy, and most of it ends up being in chinese

bring back the old days where the manual was as thick as the dictionary and just as heavy.
