Don’t forget to clean both sides of the terminal with the Q-tip. 

On the other hand, the terminals of the battery are much smaller compared to the charger.  For cleaning those parts, you can go for forded sandpaper or envelop that can easily reach there.

It is best to dip the sandpaper or the envelope in the rubbing alcohol and then use it for cleaning. To avoid these complexities, the best practice is to do this cleaning process in every 2-3 months.
