About filter washing and drying
For environments where popcorn grease and such can contaminate the filters, Barco advises the client to
purchase one extra set of filters to cover drying time, as well as taking following extra precautions and
instructions pertaining to filter cleaning and drying.
Cleansing agent
To clean sticky, greasy dust filters we suggest usage of Sodium carbonate crystals (Na

). Sodium
carbonate (Often called washing soda, soda crystals, or sal soda in the detergent section of stores) is
widely used to effectively remove oil, grease, alcohol stains … The product itself is relatively safe, sodium
carbonate is used in toothpastes and as a food additive (E500). Potential Hazards are described in the section
“Hazards”, page 352.

This cleaning procedure assumes that the filters are already removed from their slots.
Take into account that the time needed to dry the dust filters may be 24 hours or more. For that, it's
recommended to have a second set of dust filters which can be used while cleaning the first set.
Required tools
