The answer to 'carpet discolored' is that there are several common causes, including spills, sun damage, and general wear and tear. Symptoms may include faded, yellowed, or stained areas in the carpet. Solutions can range from DIY spot cleaning to professional deep cleaning or even carpet replacement in severe cases.
If the discoloration is limited to a small area, you may be able to address it yourself with a carpet cleaning solution and a scrub brush. However, for widespread or stubborn discoloration, it's best to call in a professional carpet cleaning service. They have the specialized equipment and expertise to properly clean and restore your carpets without causing further damage.
