The answer to 'my carpet is filthy' is that there are several common causes for heavily soiled carpets, including heavy foot traffic, spills, pet accidents, and lack of regular cleaning. Symptoms may include visible dirt and stains, unpleasant odors, and a dull, matted appearance. To address this, you'll first want to determine the extent of the soiling and whether it's a localized issue or the entire carpet that needs attention.
For light to moderate soiling, you may be able to handle carpet cleaning yourself using a rental machine or spot cleaning products. However, for heavily soiled or neglected carpets, it's best to call in a professional carpet cleaning service. They have the specialized equipment, solutions, and expertise to deep clean your carpets and restore them to like-new condition.
