Kohler Seat Anchor Toilet Seat Types: Which Are Harder To Stain?

Toilet seat types: Which are harder to stain? - kohler seat anchor

I have two Bemis Toilet Seats $ 40 mark (wood bar with a white painted) at the Home Depot and seemed to be more easily under the seat of the seats stain cheap plastic $ 10 from my room bathroom. Is there any kind of toilet seat you can buy, which is more resistant to stains than others? I know my main options seem to Home Depot, painted solid polypropylene (plastic) and molded wood. The seats have noted that the reference is to the coloring Kohler, and most of those who say that "stain" and are made of polypropylene.

I am looking for answers from people in-the-know (contractors, plumbers, etc..)
