Restoring a Grain Mk1 - rust removal
Hello everyone - newbie here
I bought a lovely little hand crank Grain Mk1 miniature sewing machine from a junk shop a few months ago, my first vintage machine as an adult. It has a little bit of rust on the slide plates etc. I really don't want to dismantle and soak it as I've seen a lot of people recommend in evapo rust. I really just want to be able to gently remove the rust with a gentle chemical and a q tip or something to that effect. Do you have any advice?
Thank you so much!!!
