Warm weather brings out all kinds of odors that have been lurking in our carpets. Do not reach for the carpet fresheners sold in the stores. They just mask the odor and ruin your vacuum. Liberally sprinkle baking Soda on the carpet and allow it to sit on the carpet at least overnight and then vacuum up. Baking soda absorbs odors, which means it takes the odors out of the air. You have now freshened your carpets the eco friendly way.
