Can COCA-COLA® be used to clean toilets ?

It can, and you get a similar effect if you use other acidic foods and drinks, like lemon juice. But these are not very good choices for cleaning. COCA-COLA® contains phosphoric acid, a safe food ingredient used in some of our beverages which can help clean off dirt. However, because COCA-COLA® is a beverage, not a cleaning agent, it isn’t effective at killing germs, and there are lots of products that are much better at cleaning.
