The video shows a person cleaning the inside of an oven with a cleaning solution. The person is using a sponge to scrub the oven's surface, moving it back and forth to ensure that all areas are covered. The cleaning solution appears to be foamy and is spread evenly across the oven's surface. The person's movements are deliberate and thorough, indicating that they are taking care to clean the oven thoroughly. The oven itself is a standard kitchen model with a glass door, and the cleaning solution is clear and appears to be effective at removing dirt and grime.
