Wet dust back
It is possible to use a dust back cloth dampened with some cleaning solvent. However, this is not recommended due to OH&S concerns.
There are available cleaning machines that work in the same manner as wet dusting back, such as the ECO Film Cleaner shown in Fig 12.3. These machines use felt pads to supply solvent to the cleaning cloths. The cloths are replaced regularly, depending on how dirty the film is.
All the precautions to ensure the safety of the film and the person working on the film regarding ventilation and protective equipment must be followed.
