What are the methods that you find cleaning the camera body useful? Give your experience.
I find that the leather chamois or most call them shammy or chamois leather very useful for keeping the camera surface clean after use.
After each use, just wipe the camera, grip and lens body with the shammy and any trace of oil and perspiration removed. Much better than normal chamois. But new shammy may be flakey, if it does, just give it 2 times of washing and dry.
