I used the canned air one time and was so worried while using it. I knew you weren't suppose to use it but I was desperate. Well, it didn't hurt anything, but I have never done it again. I have a 830 Bernina and I was just lucky I didn't cause any damage. I like the straw idea also. I think I am going to try that today. It needs to go to the shop but I'm in a frenzy trying to get my quilts done for Christmas and have no time to travel 1 1/2 hours to my dealer to get it cleaned.
