I would say the shiny spot around the spool pin is the clean area and the grungy dull area is the dirty part.
Use no chemicals, no Simple Green, no 409, no dish washing detergent, nothing I repeat NOTHING with alcohol in it.
Many say to use sewing machine oil and cotton balls. I've used the oil with a rag and it did work on some machines, on others not at all.
I've also used Goop non pumice hand cleaner with stain remover. That also works on some machines. Most people say to use Go-Jo non pumice hand cleaner, I'm going to try that next time I get to the auto parts place.
I've yet to find anything that will work on every machine. All they are covered with is oil residue, body oils, tobacco smoke and nicotine, fire place smoke and soot, grunge, and generations of dirt. It shouldn't be that hard to clean them. It wouldn't be except for the decals and lacquer or clear coat that's on them.
What part is broken? I don't see it. All I see is you need a new bulb and screw and nut for the bulb cover. And where is the bobbin winder?
