If you want your camera to take great photographs and last a long time, make sure you keep it clean. Never touch the lens with your fingers and when cleaning the lens, viewfinder or LCD, turn your camera downward. You should use canned air or a photographic blower brush to remove dust particles and grit. Also, use a brush in the film chamber. You can also clean the lens and other parts of the camera with a soft, dry cloth or specially made lens cleaning paper. You may also want to use lens cleaning fluid, but you should put the fluid on the lens cleaning paper, not onto the lens itself. Don't use liquids to clean the body of the camera as they can cause damage. If the mirror is dirty, clean it with a blower brush, don't use lens-cleaning tissue or solution on the mirror. If you think your camera is too dirty to clean yourself or you are unsure how to do it, take it to a camera shop.
Cleaning kits can be bought for about $10.
