I am aware of it and do take caution when using it in an emergency. I always angle it to blow it away from the innards of the machine when and if I do use it. But thanks for the show and tell, it is worth more than a thousand words of caution.

The Lady that owns a sew and vac and also has a service dept. for all machines. She told me to use the canned air, said the lint and dust would just go to the bottom. Maybe she was trying to get more business for the repairmen.

I use my dustbuster with a straw stuck in the front opening. Sounds crazy but it works.

I also never use it on my keyboard of my computer. It also has a chemical that really dries out your components in there.

Major yikes, I was told years ago to never used canned air by the dealer.

Thanks for the info.

Oh it blows it to the bottom alright, but it sticks to the inners on the way down!

I heard about not using the canned air. So, I started using my hand vac - I duct taped a drinking straw to the hose and it worked rather well as long as I left a space open in the tape to release some of the suction. (or the straw just sucked shut!)
More recently, I bought a little gizmo that was supposed to be a vacuum for a sewing machine. TOTAL waste of money. It didn't have the power to lift a bit of lint let alone clean out an area of the machine. So, never to pass on a chance to make lemonade out of lemons, I combined the two. I used the attachment pieces from the tiny useless vac, and taped it onto the tubing from the handvac. Yeah baby! That works like a charm.

Oh my gosh that is amazing how much lint is in there. I was always told never to use canned air around electronics by our computer teachers in school as they shower us what it did to computer boards.

Thanks so much for this,I have some but haven't used it yet thank goodness.
