Scrubbing vigorously is a cleaning technique that involves using a brush or other abrasive material to remove dirt, grime, and other debris from surfaces. It is often used in bathrooms, kitchens, and other areas where there is a lot of dirt and grease buildup. Scouring, which is the five-letter solution to this crossword puzzle, is a similar technique that involves using a stiff brush or other abrasive material to remove dirt and grime from surfaces.
