Full product description
Most machines will tell you when to descale. What they will not tell you is that the branded solution they want you to buy is usually citric acid and water at a heavy markup, sold in single-use packets.
This is the same working chemistry as a concentrate. Measure 2 to 4 tablespoons depending on your water hardness, mix with water, and run your machine's own descale cycle. One 12 fl oz bottle covers 8 descales at the standard 3-tablespoon dose, or up to 12 at 2 tablespoons for light buildup.
Features:
- Professional-strength citric acid – A concentrated solution formulated to remove mineral and limescale buildup from coffee machines, espresso makers and hot water systems.
- 8 to 12 uses per bottle – 8 descales at the standard 3-tablespoon dose, up to 12 at 2 tablespoons for light buildup, 6 at 4 tablespoons for heavy buildup.
- Universal compatibility – Works with De'Longhi, Keurig, Breville, Nespresso (Original and Vertuo), Ninja, Philips, JURA, Gaggia and most popular coffee machines.
- Simple process – Measure, mix with water and run your machine's existing descale cycle. No powders to dissolve and no packets to fumble with.
- Unscented and bleach-free – Supports consistent water flow and brewing performance as part of routine maintenance.
How to use:
- Measure 3 tablespoons for a normal descale (2 for light buildup, 4 for heavy).
- Add to the water reservoir and top up with water. On a Nespresso Vertuo Next, VertuoPlus or Vertuo Pop, use the 17 oz of water Nespresso's descaling guide calls for.
- Run your machine's descale cycle per the manufacturer's instructions.
- Run at least two full rinse cycles with fresh water afterwards.
