Zymol - Is it good/safe to use on machines?
Yes, I am back with another question. I just read where Zymol, a car wax product, is good for shining up those old black Singers and others. Has anyone used this or know anything about it? Do you need to clean up the machine with something else first before using it? And the big question: Is it safe to use on the old machines if they are in good shape to begin with ... so just for shining and protecting maybe? I usually only use sewing machine oil but wondered about this since it was recommended. Thanks!
