Stubborn carpet odors can be quite the nuisance! For me, a mixture of baking soda and essential oils has been a lifesaver. Sprinkle the mixture over the carpet and let it sit for several hours or overnight before vacuuming it up. This method neutralizes odors rather than just masking them. For particularly stubborn smells, white vinegar works wonders. I once had a spill that left a lasting odor until I dabbed a vinegar solution on it; the smell was gone in no time. In my search for an answer, I stumbled upon another helpful site that might be of interest. While we’re on the topic, steam cleaning occasionally can also help eliminate deep-seated odors effectively.
