Wow is all I can say. I just am amazed at this forum and all that I have learned here, today I learned I may have saved myself a lot of headache. Thank you so much for the responses. I googled canned air/sewing machine cleaning,everyone is spot on. I did not realize there was a fine mist of liquid too. I will not use it again on my beloved Janome. I'll experiment with pipe cleaners, paint brushes, makeup brushes and figure out what works for me. Again thank you so much. And after looking at my pictures on here, looks like I need to remove the plate a little more often too.
