The answer to 'why is my carpet discolored' is that there are several common causes, including spills, pet stains, sun damage, and general wear and tear. Discoloration can manifest as fading, staining, or a change in the carpet's original color. The symptoms may include noticeable spots, patches, or an overall dull appearance.
In many cases, you may be able to address minor carpet discoloration with DIY cleaning methods like blotting, spot-cleaning, or using a carpet cleaner machine. However, if the discoloration is widespread or the result of a stubborn stain, it's best to call in a professional carpet cleaning service. They have the tools and expertise to safely and effectively restore your carpet's appearance.
