Cleaning Seat Cover From Singer Cabinet
I got a 1952 model 15-91 in a mahogany cabinet while visiting our kids in Missouri. The cover on the stool is in nice condition, but a little of the vinyl-like surface layer has chipped off on the corners. Most of the surface is kind of foggy and looks like it is showing a fabric pattern from someone's pants or dress.
Are there any recommendations, or warnings, about cleaning the surface of the cover?
