The phrase indicates a cleaning instruction applicable to certain items, primarily fabrics or materials that cannot withstand standard washing methods. It means addressing stains or dirt on a limited, specific area rather than submerging the entire item in water or using a machine. For example, if a couch cushion has a coffee stain, the recommended approach would be to treat only the stained area with a suitable cleaning agent, rather than washing the entire cushion cover.
This directive is crucial for preserving the integrity of delicate materials that might shrink, fade, or become damaged through regular washing. Items with intricate embellishments, special coatings, or specific constructions often require this gentle approach to maintain their appearance and functionality over time. Historically, before the advent of modern washing machines and synthetic fabrics, specialized cleaning methods were common due to the limitations of available materials and cleaning agents.
