UGC kitchen commercial of a stain remover erasing a stubborn stain

A highly realistic 12-second vertical (9:16) UGC-style commercial filmed on a smartphone inside a bright modern kitchen during daytime. A middle-aged mother notices a stubborn dark stain on a white countertop and says with a doubtful smile, "I've tried everything... this stain just won't come off." Her adult daughter walks into frame holding a bottle of stain remover and replies naturally, "Just watch this." She sprays the stain once, waits one second, then wipes it with a microfiber cloth in a single smooth motion. The stain disappears completely, revealing a perfectly clean surface with realistic reflections and texture. The mother leans closer, gently rubs the cleaned spot with her fingers to make sure it's real, then looks at the camera, surprised, and says, "Okay... where did you buy that?" Both laugh naturally. Handheld smartphone camera with subtle shake, natural lighting, realistic facial expressions, authentic dialogue, accurate cloth movement, physically correct liquid spray, realistic wiping friction, no exaggerated effects, no jump cuts, no CGI, no slow motion, no background music, only natural kitchen ambience and dialogue, ending with the stain remover bottle clearly visible on the clean countertop.
