Can I use a canned air duster to clean my projector and are there any precautions I should take?
Epson recommends using a small vacuum designed for computers or a very soft brush (such as a paint brush).
You can use canned air dusters with non-flammable propellants to remove dust from your projector's external surfaces and intake filters. Do not spray the duster inside the projector.
Do not use canned air dusters that have a flammable propellant on or around Epson projectors. The gases may leave residue. Please read the label, or check with the manufacturer, to determine if the duster uses a flammable propellant before using it.
When air duster propellants are exposed to high temperatures, they can break down and generate toxic gases. Canned air gases can be heavier than air and may not easily dissipate or thin out. This can result in these gases remaining in or around an electrical device and possibly catching fire by static electricity, spark, or heat from the projector lamp.
