Re: Smoking-free environment
Not an expert but I believe plastic is a porous material, meaning it can absorb things like a sponge. Obviously, it's not as good as a sponge, but over time it will slowly absorb things that it's exposed to like smoke.
It's why you can dye plastic different colors.
Ever see a coffee cup stain on a table? Same principle, at least to my limited knowledge.
