Air dusters can emit solvent especially when full or shaken/used upside down and I wouldn't trust difluoroethane on plastic. Must be the same class as dichloromethane (.....ethylene?) which was early type switch cleaner, great on old ceramic switches but destroyed anything plastic. Isopropanol is much safer now - and less harmful to health and environment. I have a question about removing dust particularly on circuit boards.......I'm wary of inducing static by blasts of air or physical brushing with bristles and I know you can buy expensive vacuum cleaners to clean out the inside of IT equipment to avoid static damage; all the tools and tubing contain carbon to prevent the build up high air friction induced voltages which could fry sensitive ICs. So as my K3 #145 ages and needs a wash and brush up I wonder what is the safest way to remove the dust and spiders from inside?
