Hi, My brother has requested to borrow a CD. So whilst hunting around for it I came across his old walkman. However, I had not realised that it still contained a battery in it. The walkman is over 15 years old, and since my brother moved out around 2002 it makes the battery atleast 7 years old! Here is a link to a page I quickly set up with some pics: http://www.geocities.com/aliensrcooluk/public/BatteryInWalkman.html The reason I am emailing the group, is because a power adaptor (wall wart) was sat underneath the walkman and has some brown paint-like marks on it. I am assuming this is from the battery and am wondering what is the safest way to clean it off without ruining the adaptor. The adaptor is used to run some of our modified table-top games (which originally ran from batteries, but have been modified so that they run from the adaptor instead).
