For washables: Miriam Lukken, author of Mrs. Dunwoody's Excellent
Instructions for Homekeeping ($22, www.amazon.com ), suggests adding
1/2 cup baking soda (to absorb odor) and 1 cup distilled white
vinegar (to destroy bacteria) to the regular wash cycle.
For nonwashables: Lay them on a sheet in the sun to air out for a
day or two. Cover with a second sheet to prevent fading.
