We do a complete full cleaning of every instrument once a year..takes about a full week to do. All units are blown out with air, completely disassembled, cleaned, lenses and reflectors checked and cleaned, all shutters get pulled out and hammered flat if there is any warping, and then reassembled and "lubed" with graphite powder & blown out, the electrics & wiring are checked, repaired and plugs changed or tightened up--all bases are cleaned of oxidation and lubed with Cramolin paste. The pins on each plug get cleaned and scored with a wire brush, and separated if needed. Any other major repairs the unit needs are done at this time. The c-Clamps are checked for bending and stress cracks and replaced, or the square bolt & lock bolt run to check all threads, then get lubed & repaint the whole clamp. The safety chains are checked for slippage of the nicopress or dangerous crimping and fraying of wire and painted--any replacements are done at this time. The yokes and hinge area's have the washers replaced if needed, and all lock bolts & T handles are loosened from any over tightening and then reset to balance. Then the fixture is reassembled completely, lamped & benched. If we paint the units--we cook them for about an hour (only use high-temp paint). We then mark the fixture to our codes--9's, 12', etc,. When done--the fixture is like-new.wemeck said:How often do your shows pull down all the lights and really clean them out?
For the first time that I know of in three years we have begun the process of cleaning all our lights with watered down ammonia, soft shop cloths, and an air compressor.
Any experiences or tips from you all to share?
