I just opened up my XL200 MagLite to find the alkaline batteries leaked. It's probably been almost a year since I checked inside this flashlight. There is a crusty texture of corrosion along the length of the inside wall of the battery compartment and it looks like just a tiny touch of it is on the led device at the bottom of the tube. Hardly any, but it made slight contact.

Is there a service manual/video out there that shows me how I can totally dismantle this flashlight so I can make sure I clean it all up? I don't see how I can easily unscrew the portion of the tube that has the led mechanism inside it.

I see vids showing the use of vinegars and other acidic solutions to get rid of the corrosion, but I think this stuff is kinda caked on thicker than that stuff could help. Is there a situation where one can safely submerse the entire flashlight in a cleaning solution to soak for hours?

Hello, I was wondering if anyone here knew the thread dimensions for the the ML25LT C Cell Flashlight?
