How to freshen up carpet

The best way to freshen up your carpet without using harsh chemicals is by using baking soda.
Simply sprinkle baking soda over the entire carpet and allow it to sit overnight. The baking soda will soak up the odors in the carpet. Vacuum the baking soda the next morning.

Vacuum the entire carpet regularly. Go over all the carpet with the vacuum with three strokes on each section. If the carpet is heavily soiled, go over it seven times. Do this each time to keep the carpet looking fresh and clean.
