Cleaning the Sewing Machine

Instead of canned air, get a "mini hose" set for your vacuumn cleaner. Computer and/or electronics stores usually have them (or used to).

Not only is canned air expensive, but blowing the dust/lint around isn't particularly helpful for over-all cleanup or allergies. Also, some canned air has propellants that are considered enviromentally unfriendly.

There is on the market--small tools to attach to the vaccum cleaner wand. I call this my Barbie vaccum cleaner set. Miniture extensions, brushes, etc. For the $8 they are handy for computers, sewing machines, electronics you need TINY for.
If you don't want to invest--try this.
Take the vaccum wand, use a small disposable bathroom cup-poke a hole in the end, insert a bendable straw--the bend part away from you. You may need to tape it in place. Put the cup over the end of the vaccum wand, and you have a mini throw away set.

This works for short timed projects. The straw can get into many places.

Also another idea: Take it outside and use the air compressor on it to blow out the dust/lint then oil up the machine and you should be ready to go again. My latest machine is 20 years young and still running. My older machine is 45 years old and still running smooth. Thousands of hours and all types of materials from car seats, coat leathers, to the finest wedding dresses/baptismal gowns have come off these machines.
