Pour your baking soda (a gentle abrasive cleaner) into the toilet bowl. Scrub with a toilet brush. Then flush. Pour vinegar (a great disinfectant and deodorizer) into the toilet and repeat the scrubbing process.
It may be fun to mix the two ingredients together. (Remember your middle school volcano science project?) However, the chemical reaction just results in diluted salt water and the benefits basically disappear.
