As far as a clean up check list. I start in one end and go around the whole machine. I try to get every little part as I go. I get too distracted for a check list. I had a machine I was working on and the DGKs showed up. Well, I let them take out the lint and pick at cleaning oil out of it. We shined it up pretty... Then they left and the machine went into time out... BUT I totally missed something... and totally forgot I never finished working it over... I never did a test sew with that one - I assumed I had finished cleaning it. It was one of the worse stuck up machines - beautiful looking though... and it's motor was perfect but the machine would barely chug along. Somewhere we missed one little bit of dried on goo. It was fun letting the DGKs help but I should have gone back over EVERYTHING the next time I looked at the machine.
