e2E2 for TIN OXIDE Sensors
E2, the highest purity Tin Oxide sensor cleaner, is now available, containing less than 5 parts per million (ppm) of contamination (the whitish residue left after evaporation) It dries as quickly as it can be applied leaving absolutely no visible residue, making it the only recommended cleaner for Indium Tin Oxide coated CCD and CMOS sensor cleaning when used with Sensor Swabs.

READ CAREFULLY!
Directions for cleaning Tin Oxide Sensors:
Dispense several drops onto new Sensor Swab. With one side of the swab, firmly drag it across the sensor. Repeat in opposite direction using the clean side of swab. Discard swab. Repeat if necessary with new swab.

Note: E2™ may be used with conventional CMOS / CCD sensors.
