I have a few Maglites (4 D model) stashed around the house since you never can have too many flashlights. I bought them all about the same time and put Duracell batteries in them. There were two in the house and one in my truck-I pulled out the two in the house and brought them into our bedroom because of the impending storm. Neither worked. I opened them up and the batteries were stuck inside due to corrosion. I got all the batteries out of one (the other one has one stuck inside still) and shook out all of the crud but it still won't work with new batteries. I'm guessing the terminals are really full of crud but I can't get in there to clean them. The surprising thing is the one in my truck worked fine-the only thing I can think of is maybe batteries in the heat go bad faster? Anyway, does anyone know how to disassemble the lense end of a Maglite or know a good way to clean one out that's full of corrosion? I was thinking of mixing up a baking soda solution and swishing it around inside but wasn't sure if that would do more harm than good.
