Cleaning and Removing Rust: Restoring Vintage Sewing Machines
In this post, I'll walk you through the process of removing rust from your vintage sewing machine in order to clean and restore it. If there's rust on it, you don't want to risk having it spread to other parts of the sewing machine. Generally, most rust I've discovered is on the surface of the machine, rather than on internal parts, which were oiled/lubricated--this helped to prevent rust. Faceplates and other external metal parts seem especially prone to rust.

A Note about Vinegar
I often see the advice to soak something in vinegar to remove rust. I have not found this to be especially helpful in removing rust. For some reason, people go nuts over vinegar as a cleaning solution, but I have never seen the near-miraculous results always promised. It doesn't seem to hurt anything, but I've tried it multiple times now, and it also doesn't seem very effective.
Using a Dremel to Remove Rust from a Vintage Sewing Machine
The Rust Removal Process
This was what I started with. It's an ornate floral faceplate from a Singer 66.
I used the sanding sponge initially to remove the top layer of rust.
Then I used my dremel and metal brush attachments to finish it up. You can still see a bit of pitting and discoloration, but the rust is gone and overall, I think it turned out well!
