Why my right bud isn't charging?

the right bud doesn't really charge,what can I do?

i found out it charges if i press it harder in the case. (Don't do this) i added a bit of moisture to the bottom part of the bud so it will make "better contact" ,and for a while it worked, but the case started flashing red, indicating moisture.Now it doesn't charge at all and a pin from the case is white instead of yellow. are my buds done for?
