For Capacitive Sensors
Use Isopropyl alcohol (rubbing alcohol) and a clean cotton cloth or tissue paper to remove oily
deposits.
Alcohol is the preferred cleaning material because it dissolves oily residue and evaporates quickly.
The use of nylon brushes or scouring pads, abrasive cleaning fluids or powders, or steel wool is not
recommended.
For Optic Sensors
Use a clean cotton cloth or tissue paper dampened by water or window cleaning solution to remove
oily deposits.
Do not use a soiled cloth or tissue paper.
A clean cotton cloth or tissue paper will absorb the deposits, but a soiled cloth will
smear the deposits over the sensor’s surface.
