How can I effectively clean a toilet bowl to ensure it is sparkling and sanitized?

To effectively clean a toilet bowl and ensure it is sparkling and sanitized, start by applying a toilet bowl cleaner or a mixture of vinegar and baking soda. Use a toilet brush to scrub the bowl thoroughly, paying special attention to under the rim and around the edges. Let the cleaner sit for a few minutes before flushing. For extra sanitation, consider using a disinfectant spray or wipes on the exterior surfaces of the toilet.
