If you hate scrubbing your toilet (who doesn’t?) have I got a safer and less expensive solution for you! Cola! This dark soda is packed with phosphoric acid (it’s strong but non-toxic) plus bubbling carbonation that will clean and shine, remove stains and dissolve rust, lime scale, calcium buildup, and other deposits from your porcelain fixture. Simply pour a can in your toilet and leave overnight. In the morning swish with a toilet brush and flush. You will be left with a sparkling bowl.
