I was told my a longarm repairman NOT to use the canned "air" that is sold for computers for this reason on my longarm and also another reason not to use it on my Elna--that the canned stuff is not really air--but is canned gas and that it not only is oiled and collects dust, but also will attract moisture in the air--certainly not needed in a machine! So he suggested if I can truly find canned AIR to use on my long arm,to go ahead--otherwise I can use our air compressor (not practical) a bike pump, or better yet, the vacumn cleaner. And he suggested only a vacumn for my domestic machine cause I wouldn't want to blow bits of stuff into the case where it lodges in moving parts. Now my cheaper, traveling machines that are not computerized and I can take apart are another story! I've looked but can't find true canned air, so plan to buy one of those little specialized attachment hoses for my vacumn to clean my machines (think Keepsake catalog has them??)
