Coca-Cola as a Cleaner

What Makes Coca-Cola Such an Effective Cleaner?

Coca-Cola is carbonated, which allows it to dissolve with metal oxides and break up rust on a variety of metals and alloys. Phosphoric acid also gives it rust-busting power, while citric acid makes it an effective stain remover. Compared to commercial rust removers, Coca-Cola doesn’t contain as much phosphoric acid, so it works more slowly. However, it’s a good choice if you’re looking for a cheaper alternative.
