Both Armour All and Pledge are silicon based products. Any silicon based polish, whatever the name, will give the same results. I've used Murphy's oil soap on vinyl when I didn't have anything else, but it doesn't shine like silicon.
BTW, silicon is also a lubricant, hence the slide.
Great stuff, considering that they make gaskets and caulking with it as well.
As with all chemicals, read the label carefully.
