Here's how: Pour a full can around the rim so that it fully coats the bowl, then let it sit for at least an hour to allow the acids in the soda to break down the stains. Scrub with a toilet brush, then flush.
Or just use heated up white vinegar and Dawn, let sit overnight and flush. You can use this weekly to keep your toilet clean.
