On occasion when I cook pasta sauce (large quantities frozen for future use), my house begins to smell quite a bit like Luigi's All Night Spaghetti Factory, and since my sauce usually cooks down over the course of a coupla hours, it rather permeates the house. My quick fix is to turn on the central air blower for a couple minutes and then spray odor-neutralizing into a couple of the intake vents. A few minutes later, the entire house has a vague scent of the fragrance without my having to walk around the house spritzing every corner. (My idea is useless, of course, if you have radiators. Sorry.)
Another "folk remedy" I discovered recently was another use for Swiffer dusters after they're used up; sticker burr removal! Here in eastern Colorado (and particularly on our ~3 acres), we have an annoying abundance of sand burrs, and now that it's fall, their spiney hooks have dried hard, making them very painful to remove by hand. My husband was doing yardwork yesterday and came into the house for help removing the burrs from his back (don't ask; I didn't). As it happened, a very used Swiffer handduster was nearby, so I took a quick swipe. IT WAS MAGIC! I got the seven or so off his back and then removed the two or three dozen from his pantleg (he'd done the other one outside by hand). I've never seen those things come off so quickly and easily.
If you come by sometime this week, you'll probably find me wandering around the property looking for other miracle cures with a Swiffer. Goatheads, here I come!!!
