Cleaning rusty FW bobbin case
Hi everyone,
Just after posting about needing a bobbin case for my 1938 Featherweight, I took a chance and bought a vintage case (eBay) that comes with the bobbin case base and the gib (broken). The price was right -- $30. I just need the bobbin case. It's the same number as the one that I swap between my two Featherweights. My question is how to clean some small rust spots off the case... WD-40? Something else? I'm hoping that it's functional after some cleaning, but I don't know how to clean the bobbin case and I'm afraid to take it apart completely... there are some tiny little parts in there.
Help?
Ila
