11/ Fixture Cleaning
Regular cleaning is very important for fixture life and performance. Buildup of dust, dirt,
smoke particles, fog fluid residues, etc. degrades the fixture’s light output and cooling ability.
Cleaning schedules for lighting fixtures vary greatly depending on the operating environment.
It is therefore impossible to specify precise cleaning intervals for the fixture. Environmental
factors that may result in a need for frequent cleaning include:
Use of smoke or fog machines.
High airflow rates (near air conditioning vents, for example).
Airborne dust (from stage effects, building structures and fittings or the natural
environment at outdoor events, for example).
If one or more of these factors is present, inspect fixtures within their first few hours of
operation to see whether cleaning is necessary. Check again at frequent intervals. This
procedure will allow you to assess cleaning requirements in your particular situation.
Follow these precautions when cleaning the fixture:
Work in a clean, dry, well-lit area.
Use gentle pressure only. A soft lint-free cloth dampened with a solution of water and a
mild detergent is recommended, under no circumstances should alcohol, solvents or
abrasives be used! Use care when cleaning optical components: surfaces are fragile and
easily scratched.
