Pledge may not have silicones. I have been using it for 40 years on fabric airplanes, with no problems recoating.
cheaper stuff in similar bottles does have silicone - be careful.
My ancient Mustang convertible dash pad is 53 years old - no cracks after 40 years of routine Pledge applications.
The stuff is expensive, and only available in spray cans which run out of air before they run out of product. Still . . .
