Every sensor cleaning swab is sealed in a vacuum package which prevents contamination and allows long-term storage. Each sensor cleaning swab is head-covered by micrometer level superfine fabric cloth that brings supreme cleaning efficiency and 100% safe to the delicate surface. UES FFR24 sensor cleaning swab is specially design for Full-Frame 24mm sensors. Compatible with, but not limited to the following cameras: <ul class="a-unordered-list a-vertical"> UES sensor cleaner is made from ultrapure water, which has the resistivity of <span class="a-text-bold">18.2 M</span>  cm. Purest sensor cleaner enables the sensor chips to dry by itself and leaving absolutely no residue. It also prevents sensors from collecting bacteria. UES sensor cleaner is safe for both CMOS and CCD sensors <span class="a-text-bold">Double Seal </span>prevents leakage and contamination. <span class="a-text-bold">Please Note</span> there is a clear removable seal covers the hole enabling drops to be dispensed to the swab You don&#039;t need to press the bottle too hard to dispense a cleaner drop. It will drip naturally and smoothly from the hole. You only need <span class="a-text-bold">ONE</span> drop to apply wet cleaning on your sensor. <span class="a-text-bold">DO NOT</span> dispense too much cleaner on the swab. Before start, shoot a piece of white paper with Aperture Priority (A) mode set at f/22 or higher, so you could see where the dust is located on the sensor. You need to set your camera to a special clean mode, so the delicate shutter and mirror mechanisms stay out of the way when you clean the sensor. Go to your camera setup, and select &#039;Lock Mirror Up For Cleaning&#039;. This option will be greyed out unless your camera&#039;s battery is fully charged. (for Cameras that do not have the lock mirror up function, you could set your camera exposure on Bulb. The Bulb setting will allow you to keep the mirror up until you release the shutter.) Use the air blower to blow loose dust off the sensor. Dispense 1 drops of sensor cleaner to the head of the swab. Drag the swab slowly and smoothly from the left of the sensor to the right. Use a single movement. Turn the swab 180 degrees and drag the clean side of the swab from right to left. Throw this swab away and never reuse swabs.
