My friend, M, came over and helped me scrub down my machine. No longer is it covered in caked-on decade-old grease. We brushed away all old lint. There was some caked on thread-grease gunk on the feeder feet. My husband had to take the machine outside, and turn it in all directions to get miscellaneous dirt and dust out of it. Not an easy feat as it weighs like 2039480928 pounds.
If you remember, this is the before (Sorry for the crap lighting).
It's like an entirely different machine. Here are the knobs.
