Being a “forever chemical” may sound scary but the “forever” part means that the chemical is highly stable and not prone to reactivity. Lack of reactivity means that it is less likely to cause cancer.

The wax itself is much more likely to contain cancerous chemicals than the added Teflon and it isn’t likely to contain much.

Want some real fear mongering? Any number of the fluids used in an automobile has far more likelihood to cause cancer than PFAS will. Gasoline alone contains huge quantities of benzene as a percentage of weight which is a known carcinogen.
