P.M.
My idea of a "good smelling" house is one that simply doesn't smell like anything. I achieve that in my home by cleaning only with baking soda, white vinegar, unscented detergents, occasional borax and hydrogen peroxide bleach. People often comment on how fresh and "relaxing" my house smells, like the great outdoors. Most of the scented products available commercially actually contain toxic ingredients, some of which are central nervous system stimulants, and not exactly relaxing.
I started cleaning this way when I discovered I'm terribly sensitive to synthetic scents, including perfumes, many toiletries, air fresheners and scented detergents and fabric softeners. I have to leave people's homes quickly if they are strongly perfumed, which is awkward for the hostess and for me. So I've learned to ask first, which is also awkward, but easier to explain.
