What is a common problem associated with cleaning lamp shades?

When cleaning lamp shades, a common issue that arises is the separation of the decorative trim. This can occur because many lamp shades incorporate glued trim, which may not withstand the moisture and cleaning solutions used during the cleaning process. If the trim is not properly secured or if the adhesive fails due to exposure to water or chemicals, it can begin to pull away from the shade.

Understanding this issue is crucial for carpet cleaning technicians, as it highlights the need for careful handling and consideration of all materials involved in a cleaning task. Avoiding moisture on trims, or using methods that do not disrupt adhesives can help preserve the integrity of the lamp shade during cleaning. Other potential problems, such as discoloration, hardening of the fabric, or fading of color, can occur but are generally less directly associated with the cleaning process itself compared to the risk of trim separation.
