Clean your meeting room screen using a 70% alcohol (ethanol) spray. Do not use a product containing bleach.
Spray the liquid onto the glass screen face only and use a soft cloth to gently wipe over the whole unit. Be careful not to get liquid in the ventilation slots at the rear of the unit or any other openings. Alternatively, spray the liquid directly onto a cloth and then wipe the unit. Frequent cleaning in this way will not damage the glass screen.
Surface wipes that are impregnated with a synergistic blend of bactericides, surfactants and alcohol, can also be used.
