To prevent marks or stiffness after wet cleaning velvet fabric, what should the technician do?

To prevent marks or stiffness after wet cleaning velvet fabric, grooming the velvet with a brush is crucial. Velvet is known for its plush, soft texture which can easily be disrupted during the cleaning process. The fibers of velvet are delicate and can become matted or misaligned if not treated properly after cleaning.

By using a brush specifically designed for velvet, the technician helps to realign the fibers and restore their natural luster. Brushing allows for the removal of any water marks that may have formed during washing and helps to fluff the fabric back to its intended softness. This step ensures that the velvet maintains its characteristic look and feel after cleaning, which is vital for customer satisfaction and the longevity of the fabric.

Applying steam may also help in some situations, but it carries a risk of water damage if not applied carefully on velvet. Similarly, using a vacuum cleaner doesn’t address the potential matting of fibers effectively and may not contribute to the restoration of the velvet's original texture. Thus, grooming with a brush is the most effective and appropriate method to care for velvet after wet cleaning.
