Crumbs in your keyboard? It's probably time to clean your computer

Once inside your computer, use a vacuum cleaner's nozzle to carefully suck up dust. However, be sure not to move the cooling unit's fan, as this could generate a charge that might damage the motherboard.

Crumbs, dust, spilled soft drinks – computers and their accessories have to endure quite a lot. Whether at home or at the office, the devices should be cleaned at least every now and again. 

However, since you can do a lot of damage if you don't properly clean your devices, it's worth keeping a few things in mind.
