Final answer:
Restorers may anticipate problems with wet cleaning fabric lampshades with decorative trim, such as fraying and color bleeding.
Step-by-step explanation:
When wet cleaning fabric lampshades made with delicate decorative trim, restorers may anticipate problems related to damage or color bleeding.
The wet cleaning process can cause the decorative trim to fray, unravel, or come loose from the fabric lampshade. Additionally, the moisture in the cleaning solution may cause the colors of the trim to bleed onto the fabric, resulting in staining or discoloration.
To prevent these problems, restorers should take precautions such as spot-testing the cleaning solution on a small, inconspicuous area of the trim and using a gentle handwashing technique or a dry cleaning method instead of wet cleaning.
