For some parts of the camera that are not accessible by hand, the whole machine part can be treated with graphite powder solution.In addition, due to the age of the long, and heat, humidity and other factors, can also be used to dry the camera lubrication.The following small make up of tianshengda graphite explains the characteristics of the lubrication treatment of graphite powder in the camera:

The specific method is: a small amount of organic solvent into a small container, mixed with a small amount of graphite powder, graphite powder sank to the bottom of the container, the solution is no longer cloudy.Mix the solution with a bundle of mirror paper and apply the solution to the machine parts.Sweep later: fill the container with some organic solvents.Repeat the above action, the whole part to be coated with graphite powder solution many times, followed by compressed air dry liquid.

Again, I want to emphasize here that the amount of graphite powder and organic solvent should be as little as possible, and the action should be as fast as possible.This treatment won't damage the camera, but if you're not careful, it can contaminate some parts.Graphite powder can be removed with detergent, but it is not easy to remove.Take special care not to get graphite powder on your hands, or your black fingers will stain anything you touch, especially the camera case.

The above process is also applicable to the body and lens shutter assembly of a single lens reflex camera.
