I tend to keep one foot on the foot pedal, so I TRY to remember to turn the machine off. I use canned air first to get rid of any loose stuff, then a cheap paint brush on every part I can reach, then use the canned air again, oil what needs to be oiled and it's good to go. I also got into the habit a long time ago of cleaning the bobbin area with canned air every time I change the bobbin, then give it a good cleaning when I'm done with each project. I usually sew three or four days a week, sometimes just to hem something and other times for a few hours at a time.
