But Hair. It works.... somewhat. Works because of the charge buildup on the hairs. Also it physically moves the dust away. 2) Hi Tech Brush.... Not hair, but some synthetic product....carbon fiber is the most recent.... Advantage is higher ability to make and take a charge. Kostiner made some and they work remarkably well. Kostiner has been out of business for at least 5 years.... Hard to find. 3) Brush with anti nuclear, radioactive or otherwise malevolent source of charge. Obvious problems.... Static Master Brushes....I have several and they work pretty well. 4) Charge from electrical source... Brushes sold by Zone VI "in the old days". They plug into the wall and charge the brush. This one does work well, but it costs a small fortune ( $200 USED) and is hard to come by since they were discontinued maybe 15 years ago.... 5) Charge sources form other products.... Zero Stat... used a crystal cell that was poked and sent out a charge. This works pretty well too. 6) Air blowing.. from human breath to canned air. 7) Air + Charge creator.. used in the industrial areas fro elimination of static charge buildup ( typically into he semiconductor industry 20 years ago) My preferred way is to keep the negatives clean and to use first the Zero Stat, then the Kostiner Brush and finally a blast of canned air. If that does not work, then the Zone VI brush plus the canned air. Frank Filippone red735i@earthlink.net
