Was it ok to allow my mother to clean my recently aquired 1966 ss flaretip using hot water and vinegar on a paper towel? It looks shinier on the doors, inside, and on baseplate. The doors look like they even close tighter. If you watch from the side as they close you see the them close flush with the center piece then move away and flatten out. before they were just flush with center piece. The center piece even looks like its moving up and down with the doors opening and closing. I don't think it did that before. The tto knob feels like its running smoother as well.
