How to maintain a SLR camera if it is not maintained for a long time

If you don't use it for a long time, the maintenance method of SLR camera is as follows:

First, it must be cleaned first, and the dust and sweat stains on the lens surface of the fuselage should be wiped clean.

2. Remove the battery and memory card and install the lens cover.

Third, moistureproof. If you only have a camera and a mirror, put it in a sealed camera bag and use a desiccant (color-changing silica gel) to absorb water. If there are many equipments, you'd better buy a drying oven with humidity control. Electronic equipment needs to be well protected from moisture, but it should not be too dry. The rubber part of the SLR camera will crack due to drying, and the adhesive will lose its viscosity due to water loss. The optimum storage humidity of SLR cameras is 40%-55%.

Fourth, if the SLR camera is taken out for a long time, it's best to take a few photos every month to make the components in the camera move normally, or to charge and discharge the battery to enhance the ionic activity in the battery.
