CLEANING
The charger does not normally 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 damp cloth.
Never use sharp/pointy objects to clean the charger.
