@iscosha,
I think most of them end up with clean smelling laundry, even if they have to add something just for the scent.
Fabric softener is often a bad choice. For winter clothing, it can impair the insulating ability. For summer clothing intended to wick moisture, that ability is also degraded.
As a matter of fact, fabric softener is mostly used by women to mark their territory. You might notice that when a young lady meets a nice, personable, and prosperous looking man, she will take a discrete sniff. If she gets a whiff of softener, she will quietly move along.
