Keep it clean

Sensors, mirrors and internal components may be delicate, but cameras are generally well-sealed and pretty sturdy beasts. You won't have to clean your camera too often, unless you notice dirt on the outside or blemishes on your images.

It's pretty straightforward to ensure your SLR stays clean: keep it in a bag when not in use, give it a wipe every now and again, and make lens changes quick. It goes without saying that you should keep caps on lenses and the camera body whenever the lens is off, even if it's only for a few minutes.

Next time you get a pair of shoes and that little sachet of silica gel falls out, don't chuck it away. Instead, stick it in your camera bag to absorb moisture.

If, after following the above steps, you find yourself faced with a bit of dust or an imperfection you just can't shift, don't panic. Professional cleaning services are available, and although they are more expensive than the DIY route, they produce guaranteed results.
