Overview

• Consumer outlets have validated DIY cleaning hacks using cola, salt, baking powder and vinegar as eco-friendly, low-cost replacements for chemical oven cleaners.
• Cola’s phosphoric acid can dissolve organic residues and light rust when applied to cooled trays for at least 30 minutes or overnight.
• Mixing cola with baking powder into a paste boosts its power to lift years-old burnt-on stains within two to three hours.
• Heat treatments using table salt or a baking powder-and-water paste soften light to moderate grime by warming trays at low temperatures before gentle wiping.
• Soaking trays in a mixture of vinegar, hot water and optional lemon juice then heating at 200 °C for 15–20 minutes helps break down grease and neutralize odors.
