A DSLR camera is an expensive investment. You buy a camera, hoping that it will last for years. With proper care and maintenance, you can extend the life of your DSLR camera. You should protect it from dust and dirt. To make that happen, clean it from time to time. Make sure that you use cleaning solutions and microfiber cloth only. Once you are done cleaning, you need to store it away somewhere safe. The best thing would be to keep it in the carry case. But just keep it in a place where it will not be exposed to sunlight.
