Laser and sensors are virtually maintenance-free. For applications read the manual carefully.

To maintain the brightness of lasers and the accuracy of sensors it is necessary to keep the glass clean. Please remove dirt particles with a soft brush. This way you won't scratch the glass.

Don't use compressed air!

Further cleaning may be done with a soft cloth, lukewarm water and a household washing-up liquid / dish soap. (Don't use tabs for dishwashers!) More aggressive cleansing agents may damage the sealing materials.

Please keep in mind the protection class of your laser or sensor! In general, you should wring out your cleansing cloths before use.
