Human: What's the best way to clean a ring that's been lost or dropped in the toilet? Assistant: 
The best way to clean a ring that has fallen into the toilet is to use a combination of baking soda and hydrogen peroxide. Mix equal parts baking soda and water, then add a few drops of hydrogen peroxide until you get a paste-like consistency. Scoop up some of the paste with a spoon and gently scrub the inside of the toilet bowl. Once it's cleaned, rinse off any remaining paste and flush the toilet to remove it from the bowl.
