The BEST nicotine remover I have found is GoJo Hand Cleaner, the white kind, NOT the orange. It takes off nicotine and hand oils faster than anything, and I have yet to find any panel that it damages. Of course always spot check FIRST! 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line & TR-4/C Service Supplement CDs <www.k4oah.com>
