Diet coke is a popular diet soft drink and can leave stains if spilled. The chemical composition of diet coke includes carbon dioxide, water, caffeine, phosphoric acid, and artificial sweeteners. These components can contribute to staining or damage on surfaces such as fabrics or carpets.

Maintaining a clean and orderly environment is important for ensuring that spills can be cleaned up and potential damage is minimized.
