The answer to 'why is my upholstery dirty' is that there are several common causes, including regular wear and tear, spills and stains, pet hair and dander, and accumulated dust and dirt. Upholstery can become dirty over time due to the oils and residues from human skin, as well as environmental pollutants and debris that settle into the fabric.
Symptoms of dirty upholstery may include visible stains, discoloration, a dingy appearance, and a buildup of grime. In some cases, the fabric may also feel rough or sticky to the touch. Proper cleaning and maintenance is important to keep upholstery looking its best and extending its lifespan.
