It may seem counterintuitive to use Coca-Cola as a cleaning product, but if you are in a pinch it can actually come in quite handy. The ingredients can be abrasive and help you to clean certain items, especially a toilet bowl in a pinch. All you have to do is heat up the coco-cola, pour it into the toilet bowl, and let it sit overnight. The next morning, after a flush, it'll be as good as new.
There is a rumor that Coca-Cola and other sodas were actually originally created as cleaning supplies. Whether or not that is true, this hack is probably making you a little suspicious.
