Clean dust from your keyboard

If you are using your keyboard for quite some time, there are good chances that it might have collected lots of dust particles and debris. These particles might be clogging your keys and preventing them from functioning properly.
This problem is very common in mechanical keyboards because of enough space between two keys. So it is necessary to properly clean your keyboard using a cloth. You can also turn your keyboard upside down and shake it so that the dust falls out.
You can use a key puller to pull out all keys from the mechanical keyboard or blow away the dust by using a small air blower.
