Keep your coffee tasting great and your machine running smoothly with De'Longhi’s EcoDecalk descaler. Limescale buildup from water minerals is a major cause of machine problems and bad-tasting coffee. This eco-friendly solution is made with plant-based lactic acid – it’s powerful enough to dissolve scale but biodegradable and safe for your machine’s food-grade parts. It’s not just for De'Longhi; it works great with other brands like Breville, Ninja, Philips, and more. Each bottle has about 5 uses, so this 2-pack is roughly a 30-month supply if you descale every 3 months. Just pour 100ml (one dose) into your water tank and run the descaling cycle as per your machine’s instructions. It’s an easy, affordable way to protect your investment and enjoy perfect coffee every time.
