There is one spot below our sink that gets the most wear and tear because it's the cabinet where we keep our garbage and a lot of gunk gets on it, you can see where the paint has rubbed off a little, but it's very minimal and I have a super easy solution to touching it up.

I can't stand having layers of gunk on my face and with my sensitive skin, I don't like to clog it up with random products every day. (mindbodygreen.com)
Because there's lots of gunk in your gas tank, e.g. sand, rust or other debris, when you have the tank filled, this gets swirled around and sucked up by the fuel pump. (mechanics.stackexchange.com)
