If you're worried about the smell, in my experience the scent of the wipe far overpowers the scent of the poo. As for the visual part (or just the squick factor of having exposed poo in your trashcan), I find that the combination of using a lidded trashcan and folding the wipes carefully before throwing them away makes it a non-issue.
I've read they're not safe for flushing, so I don't buy them.
Yeah you gotta throw them in the trash, it's honestly not that big a deal but it is wasteful I suppose.
With possible skidmarks? A hell naw
