2. Fold the tissue several times to match the width of the IR lter—you might use two
or three tissues at a time if necessary (to give you a better grip). Be sure to fold the
paper so that the coated glossy side faces outwards—do not use the other side, as it
can do more harm than good!
3. Gently place the folded tissue onto the edge of the lter using two or three ngers.
Be sure to wipe the entire surface evenly. Sweep the lter only once. Do not wipe the
same area twice with the same tissue as you might reapply dirt removed in the rst
sweep.
4. Finally check if the IR lter has been properly cleaned either by visual inspection or
by mounting the digital back to the camera and making a shot. If further cleaning is
needed, repeat cleaning procedure.
Cleaning with an E-Wipe
E-wipes are individually packed wet tissues.
1. Tear at the notch to break seal.
2. Remove the e-wipe from its packaging and continue without delay.
3. Fold the tissue to match the width of the IR lter.
4. Apply rm pressure using two or three ngers at the edge of the wipe to ensure an
even, rm contact with lter surface. Wipe the surface in one unbroken motion.

Note! Do not use same side of the e-wipe twice as you will be likely to reapply any
particles removed in the rst sweep.
5. Finally check if the IR lter has been properly cleaned either by visual inspection or
by mounting the digital back to the camera and making a shot. If further cleaning is
needed, repeat cleaning procedure.
Cleaning the housings
If the back becomes dirty do not use any other solvents. Clean it with a so, clean cloth
lightly moistened with water only. Do not allow water to enter any sockets or open-
ings.
