Silicone will make plastic on the outside of your car appear like new again but the effect is short-lived, like two weeks, and there'll be a period after that where it looks blotchy. Door rubbers are OK with silicone but I've used vaseline to similar effect.
It was everywhere after my MIL wiped the whole house down. That spray was strictly not approved for indoor use, and it did not go away ever. My mother finally found a cleaning product that seemed to help, but this was a huge PITA for months and we were so mad. We thought about redoing all wooden floors for ~7k € (in a rented place after all).
I was also angry at me, because I know that several larger production facilities have strictly banned silicone based products from their premises, because it will contaminate everything it touches (and everything that thing touches) for the further production steps, e.g. painting. You will never ever get that product off these surfaces again, and it will continue to contaminate until you throw everything in the bin.
All the professionals we talked to were convinced that they know no way to get rid of silicone on surfaces (especially indoors in living quarters with small kids present), and sanding the floor down would probably just spread it - cross-contaminating the surfaces again.
There are uses for silicone spray (bicycle maintenance, outdoors, cars, etc.), and I would have one at home for these cases - but that whole product line is strictly forbidden at our home forever.
