Lens 2 (overhead+follow-up): gently press the brush into the frying pan with foam water (the bottom of the pan is slightly greasy), quickly sweep the brush after it fits the pan surface, close-up: the greasy dirt is wrapped in foam by the brush hair, instantly dissolved and dispersed
Lens 3 (close-up of details): focus on the brushed area, the original oil stain disappears completely, leaving only the spiral texture formed by foam, showing the soft connection of brush hairs without scraping the pan
Touch lens 4 (close up): After cleaning, gently wipe the surface of the pot with a dry cloth, and take a close-up of the pot surface in a smooth and scratch free state;
