Summary: Professional sensor cleaning for dSLR cameras
Comment: Photographic Solutions products are the manufacturer-recommended sensor cleaning products for many digital SLR cameras. Their Survival Kits are a handy way to get a small set of swabs, cleaning solution, and extra cleaning pads in a easy to carry package. One of these kits is good for 2-4 cleanings; frankly, unless you frequently change lenses in a dusty environment, this may be all you need for the useful lifetime of your camera.
I currently shoot with a Fuji S2 Pro, and the Survival Kit #1 is the recommended kit for my camera. Digital Solutions has simplified instructions in the kit, but they also maintain the manufacturer's own instructions on their website (handy, since each camera has different settings to lock up the mirror while cleaning, etc.).
Be sure to only swipe in one direction and only once per swab, so you do not scratch your sensor.
