It's corrosion from traces of battery electrolyte. Clean it off with
vinegar, that'll react with the alkaline electrolyte and neutralize it. Then
wash it off with water and dry it out.



As well as cleaning the area it would be a good idea to smear the terminals
and any other metal parts in the battery box with light grease to prevent
further deterioration. you don't have to clean the grease off to use the
scanner as it wont interfere with anything.
