In the video, a young woman is seen holding a muffin tin and a cupcake liner. She is wearing a bright yellow shirt and glasses. She then proceeds to demonstrate how to use the cupcake liner to clean the muffin tin. She places the liner inside the muffin tin and uses it to scrub the inside of the tin. She repeats this process several times, showing how effective the cupcake liner is at cleaning the muffin tin. The video is shot in a well-lit room, and the woman's actions are clear and easy to follow.
