Regular oil in Morse machine?
My father in law was "helping" me and he oiled my mom's sewing machine for me. I think he used WD40 or something like that. Is the machine going to be ruined? I set it up and was about to use it in December and I got a shock so I need to get it rewired. It's been sitting in my garage since then unused. If he used cooking oil or something will it be frozen when I try to use it? I don't know why he even touched it....
