What is a potential problem with using hot water extraction cleaning?

Using hot water extraction cleaning can indeed lead to the issue of overwetting the fabric. This method relies on a combination of hot water and a cleaning solution being injected into the fabric and then promptly extracted. However, if too much water is introduced or if the extraction process is not thorough enough, the fabric can become excessively wet. Overwetting may lead to several complications, including prolonged drying times, potential for mold or mildew growth, and damage to the upholstery structure.

In addition, overwetting can also contribute to soil resettling, as dirt and grime can remain trapped within the damp fibers. Proper technique and equipment are crucial to mitigate this risk, ensuring that just the right amount of moisture is used and removed during the cleaning process. Thus, when performed correctly, hot water extraction can effectively clean fabrics without causing these issues, but improper execution can lead to overwetting, which is a significant concern in upholstery cleaning practices.
