BRUSHOFF is unlike any other sensor brush on the market. The BRUSHOFF design evolved from a NASA design and was engineered to meet their rigorous requirements and specifications. Hold the BRUSHOFF and you will instantly see that this is a solidly designed electronic tool utilizing science to produce unparalleled cleaning power! Although the brush head is remarkably soft, the brush core is entirely electronically conductive, through an ingeniously designed grounding plug.
BRUSHOFF is conductive because the dust and lint that attaches to the sensor or lens surface is attached there electronically [dust has a negative charge and the sensor/ lens a positive one]. Breaking that electronic bond is the only way to both remove the debris and discharge the sensor or lens surface so new particles are not again immediately attracted to it. A mere artist brush cannot clean all of the dust, nor can it prevent dust accumulation, even immediately after its use.
To draw a parallel, the sensor surface is much like the face of a computer monitor. The dust is very hard to wipe off with a dry cloth. The result of trying is better described as “dust rearrangement” rather than “dust removal”. Use BRUSHOFF to prove it to yourself. A conductive brush can, if it is grounded, brush the dirt cleanly off the computer screen just as it will off your sensor. No longer attracted, the dust easily falls off.
As the amount of charge (and therefore the amount of attraction) on either the sensor or the dust is unknown, using a fiber with a predetermined amount of positive charge hoping to electronically “vacuum” up the debris, may or may not remove all of the dust particles. It will remove particles when the fiber’s positive charge is greater than the sensor’s positive charge.
IMPORTANT: In some cameras, the baffle is covered by a fine oily residue which is used as a lubricant. If any of the BRUSHOFF bristles come in contact with this residue, it will cause smearing on your sensor. Avoiding the baffle altogether is next to impossible. Thorough cleaning of the brush will be needed using Eclipse or Aeroclipse and PEC*PAD. If oil transfers to the sensor, from the brush, use the correct size Sensor Swab and Eclipse or Aeroclipse to clean.
