What Makes Coca-Cola a Cleaning Agent?

Coca-Cola isn’t just a drink — it’s a chemical cocktail. Its cleaning power comes from three main components:

• Phosphoric Acid: This gives Coke its tangy flavor but also makes it mildly corrosive. It’s strong enough to dissolve rust, limescale, and mineral deposits.
• Carbonation: The fizz helps lift grime and debris from surfaces, especially when combined with gentle agitation.
• Sugars and Caffeine: While not directly cleaning agents, they contribute to Coke’s overall chemical profile, which can help break down organic material.

Why Add Salt?

Salt enhances Coca-Cola’s cleaning power by adding a mild abrasive texture that helps scrub surfaces without damaging them. Salt is especially useful for:

• Scouring metal surfaces without scratching
• Absorbing moisture and aiding in stain lifting
• Breaking up gunk and grime when combined with acidity

Together, Coke and salt form a gentle yet surprisingly effective cleaner for household tasks.

How to use it:

• Mix Coke and salt in a bowl.
• Drop in the tarnished items.
• Let them soak for 5–10 minutes.

⚠️ Important Tips and Precautions

• Always test first: Before using this method on delicate surfaces or fabrics, test in a small, hidden area.
• Don’t use on granite or marble: The acidity in Coke can damage natural stone.
• Rinse thoroughly: After cleaning, always rinse with water to remove sticky sugar residues.
• Avoid on electronics: As tempting as it may be, never clean electronics with Coke — the liquid and sugar can cause damage.
