What phenomenon does fume fading refer to in carpets?

Fume fading specifically refers to the phenomenon where the color of carpets changes as a result of exposure to airborne pollutants. This can include a variety of substances such as smoke, chemicals, or even dyes from materials in close proximity to the carpet. Over time, these airborne pollutants can interact with the dye in the carpet fibers, leading to a noticeable alteration in color, which is often uneven and can create a patchy appearance.

Understanding fume fading is crucial for professionals in carpet cleaning because it highlights the importance of maintaining clean indoor air quality. While other factors such as sun exposure, inappropriate cleaning methods, or moisture can also affect carpets, fume fading distinctly focuses on the impact of environmental contaminants that may not be immediately visible but can cause significant long-term color alteration.
