Proper extraction is necessary to avoid which common issue with carpets?

Proper extraction is essential in carpet cleaning to prevent wicking, which is a phenomenon where soil and stains that have been deeply embedded in the carpet fibers are drawn back up to the surface after cleaning. This occurs particularly when moisture remains in the carpet or when the extraction method is insufficient, leaving residues behind.

Inadequate extraction can lead to the reappearance of stains, which is frustrating for both the technician and the client, as it seems the cleaning was ineffective. When extraction is thorough, it removes both the soil and cleaning solutions, minimizing the likelihood of wicking. This is critical in maintaining the appearance and cleanliness of the carpet over time.

Other issues mentioned, like fading, streaking, and breaking, are not directly tied to extraction methods but rather relate to different factors such as exposure to sunlight, incorrect application of cleaning solutions, or the quality of the carpet fibers themselves.
