CLEANING
The charger does not generally require cleaning. If necessary, disconnect
the charger from the power supply and carefully wipe off the charger with
a soft dry cloth
If you notice any dust in the charging well, gently blow it clean. If this is
not enough, gently clean the charging well with a cotton bud.
To remove earwax from the charger, carefully wipe with a soft cloth with a
bit of mild household detergent.
Never use sharp/pointy objects to clean the charger.
