With a microfiber cloth slowly wipe the exterior of your body camera and LCD screen.
Also clean the area of the viewfinder by blowing some air and wiping it down, using an air-blower blast some air into the surface of your viewfinder to remove stagnant dust on it.
Wipe down the lens barrel by means of soft cloth and brush for areas that would not be reached by wiping.
After blowing, brush the area where some small dirt particles are seen, especially with the edges. Note: Do not use a compressed air canister as it could produce damage to your camera.
Apply some cleaning fluids to the cloth and gently wipe on the lens glass and exterior surface of the lens.
Lastly, clean the cases and caps where trap dirt and dust are always present.
