Which cleaning method should be avoided to minimize cellulosic browning?

To minimize cellulosic browning, it is crucial to avoid over-wetting when cleaning carpets that contain cellulose fibers. Cellulosic browning occurs when cotton or other cellulose fibers become excessively wet, causing them to swell and then dry too quickly, which can result in the browning of the carpet. Over-wetting can lead to this issue because it allows moisture to penetrate deeply into the fibers, creating an environment conducive to browning as the water evaporates rapidly.

Maintaining appropriate moisture levels during cleaning helps preserve the integrity and color of the fibers. By avoiding excessive water, you mitigate the risk of damaging the carpet through unwanted browning. Selecting methods that ensure the carpet is cleaned effectively without saturating the fibers will help maintain the appearance and longevity of cellulosic carpets.
