Hi guys.
I have an Oral B/Braun electric toothbrush that sits on it's charger, something like this
There is a build up of a powdery substance where the battery & charger contact. I think this is battery acid. After using the toothbrush I always rinse it. I think the water is running down the toothbrush to the area where the battery & charger make contact.
Is the water causing the buildup of battery acid? Is this doing any harm to the battery or charger? Is there a special way to clean battery acid?
Any info is appreciated.
Thanx 4 looking.
