In order to obtain maximum efficiency from the HBS, both surfaces must be kept clean and free of dust
and/or oil. NEVER TOUCH SURFACES WITH BARE HANDS.
Dust can be removed with a clean stream of air. For removing dirt or oil, it is recommended to:
1) use (if available) an ultrasonic bath
or;
2) rinse both sides with spectrophotometric grade methanol or isopropanol to remove
particles and complete cleaning with the drop and drag technique, using a soft lint free
lens tissue with spectrophotometric grade methanol or isopropanol.
Avoid using acetone, as it may leave stains or residues on the HBS surface if not used properly.
If these cleaning methods are not sufficient to remove contamination from your HBS, contact the nearest
Gentec-EO inc agent or representative.
