Techspray dusters (commonly called "canned air", "compressed air", and "dusting gas") blow away dust, microscopic contaminants, lint, metallic oxide deposits and other soils that can damage sensitive electronics. When these contaminants get in the way of vents or fans within the device, they create a build up which leads to overheating and/or shortages.
Techspray dusters do not contain additives that can contaminate sensitive electronics. Retail dusters generally have bitterant added to prevent huffing. This same bitterant can lead to unwanted and potentially harmful residues that can build up over time.
