Does Carpet Stains Fade Over Time? - An Expert's Perspective

Carpet stains can be a real nuisance, and if not removed promptly, they can cause permanent damage. Not cleaning or vacuuming them regularly can lead to a rapid loss of color. It is common for spots to reappear after carpets have been cleaned, and this is often due to the use of too much detergent. Traditional carpet cleaning methods, which lack sufficient suction power, are unable to extract all the chemicals injected into the carpet.

When inspecting carpets for stains, it is important to look for discolorations, darker areas along the walls, and reddish spots that could be from spills. If the stains are actually bleaching spots, it means that the carpet has lost pigment and there is no way to restore it with any cleaning. Absorption occurs when a stain is so deep that it has penetrated the fibers of the carpet until it reaches the back of the carpet. Some carpet cleaning companies use a pre-spray with bleaching solution to clean carpets, which can later appear in the form of light spots in places where the pretreatment was applied unevenly. If too much moisture is used when trying to remove a persistent stain, it can saturate the area and allow water to penetrate the support and the bottom layer of the carpet. The vulnerability of carpets to discoloration by light (or photooxidation of its original pigments) depends on the type of fiber in the carpet fabric and on the chemical composition of the pigments used in its manufacture.

When pigment is lost, an expert may need to cut out the discolored area and glue a patch with glue. In conclusion, carpet stains can fade over time if not removed promptly. However, if they are not cleaned or vacuumed regularly, they can lose their color quickly. If stains reappear several weeks after being professionally cleaned, it is likely due to excess detergent. Professional carpet cleaners may need to use pre-spray with bleaching solution to remove persistent stains.

The vulnerability of carpets to discoloration depends on its fiber type and chemical composition.
