If it even needs to be said, the boxes of baking soda in the refrigerator and freezer do make a difference. Buy the cheapest store brand, open the lid, and change them monthly. (You don't need those fancy expensive ones labeled as being for refrigerators.) And I do not keep any smelly organic garbage in my trash can--I keep it frozen in a ziplock, and get rid of it when the trash bag goes out to the dumpster. I clean the bottom of my Simple Human waste can with a mixture of baking soda and lemon juice--let it fizz for a while, then just rinse it out. So no garbagey trash can smell. I don't let the dirty clothes in the bin linger too long--when I have a load, I go down to the laundry room and wash it. And lingerie is washed daily by hand. I just try to keep the apartment clear of anything that might allow odors to build up. I don't get any car odors, but I don't let kids eat in my car, and I seldom eat in there myself. The trouble with dashboard dining is that you always end up spilling something sooner or later. I don't smoke, so there's no problem with smoke odors in my apartment or car. My dog is only ever in his crate in the car, so no odors from him. Any pet accidents in the house were always cleaned with Natures Miracle--highly recommended. The apartment has wall-to-wall carpeting, and I get it cleaned once a year with that dry foam method when the local vacuum store has a cheap sale. (They use it as a come-on to sell vacuums, but I just politely ignore that piece.) OP, we really need you to be more specific about what is causing the odors you are posting about.
