What are technicians advised to monitor for when cleaning fabric to avoid browning issues?

When cleaning fabric, technicians are advised to monitor for over-wetting because this can lead to browning issues. Browning typically occurs when moisture is allowed to penetrate into the fibers of the fabric excessively, particularly if the cleaning solution is not neutralized properly afterward or if the fabric does not dry quickly enough. This excess moisture can facilitate the release of sugars and oils inherent in the fabric, which can then oxidize and manifest as a brown discoloration.

Maintaining appropriate moisture levels during the cleaning process is essential to ensure that the fabric not only remains clean but also retains its original appearance. Techniques such as using the correct amount of cleaning solution, ensuring thorough extraction of moisture, and employing appropriate drying methods help mitigate the risk of browning associated with over-wetting. Proper training and adherence to best practices in upholstery cleaning solidify a technician's ability to avoid such issues effectively.
