There is a vintage sewing machine and a featherweight site on QB. There is alot of information. I air the boxes out in the sun, wipe them down with lysol sprayed on a cloth. Do not spray right inside the box, makes a mess. Also, there is a distinct engine oil smell to most of these beauties. I spray pledge on a cloth and buff them up to a nice shine. I also store the machines with the boxes opened a bit. I put a febrez closet sheet in each of them. I hope you and Lydia enjoy many hours of enjoyment. Take her to sewing classes, she will love the outing.
