Whether you're a smoker or not, you can probably agree that one aggravating aspect of tobacco is the odor that clings to everything. The smell of smoke will come right out of most fabrics when you wash them as normal, but fabrics that lock in odors and are sensitive to washing, like wool, are a bit trickier.
To remove tobacco odors from wool clothing, run hot water into the bathtub and add 2 cups white vinegar. Then hang the garment on the shower rod and close the bathroom door. The vinegar in the rising steam will remove the smell of smoke without damaging the fabric.
