One solution, I use is to buy a new "liquid spray can" which uses air by room air being injected by hand presses of a trigger pump into a spray bottle to pressurise the 'liquid contents' up a plastic 'straw' to nozzle by squeezing a trigger. Like a disinfectant or surface cleaning liquid spray bottle. Do not re-use a formerly liquid containing bottle! Do not put anything into the new spray bottle, use in new and dry condition with a lot of trial presses beforehand. Store in a dry cupboard before use. "Spray air" across fan and parts to remove 'dust'. Have a vacuum cleaner nozzle at least two hands widths away from item being cleaned to suck in sprayed air and dust or rather pull air away from item being cleaned lasted air does not resettle on board or fan or heat pipes filters to atmosphere. Good finger exercise, noisy, can be fun. -- regards Eion MacDonald -- The Mailing List for the Devon & Cornwall LUG https://mailman.dcglug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
