I've heard that canned air is not good because it blows the fuzz deeper into the machine where you can't get it out. But I'm no expert on anything.

QUOTE=pollyjvan9;5414812]I have never been to a Harbor Freight but have been given items as gift that were bought there and I have been wondering if they have the cheaper canned air and if it is safe for sewing machines. I usually buy it on sale at Hancocks but it is still expensive and I use it a LOT. I am definitely going to get a set of those skinny brushes.[/QUOTE]
