Forget baking soda. I live in Las Vegas, where water is extremely hard and forms a ring around the toilet. I have tried everything for 16 years. I now use a pumice block. It is so amazing. It’s been at least 3 months, nothing has formed around the toilet. I just clean with a brush, once a week.

Make a paste of baking soda and hydrogen peroxide and apply to your toilet surface. Let sit for 1/2 hour or so and then scrub thoroughly with a scrub brush. Repeat as necessary.

Here is a great video that shows how to do it with baking soda and vinegar: https://www.youtube.com/watch?v=ZucsFQHdCKE

Drain the water from the bowl. Apply the baking soda straight or making a paste of baking soda and hydrogen peroxide. Then scrub and rinse.
