The statement "Coca-cola is an excellent stain remover" is untrue because Coca-cola is a carbonated soft drink and not a cleaning product. It contains ingredients such as high fructose corn syrup, caramel color, and phosphoric acid which are not suitable for stain removal. It is not recommended to use Coca-Cola as a stain remover. there are many other products that are specifically designed to remove stains that are more effective than Coca-cola.
