Full product description
A citric acid descaling concentrate for Keurig single-serve brewers. Two tablespoons per descale clears the calcium and mineral buildup from the heating element and water lines, without the vinegar smell or aftertaste. One 16 fl oz bottle gives 16 descales, about four years at a quarterly cadence.
Features:
- 16 descales per bottle - 2 tablespoons (1 fl oz) per descale.
- Mixes instantly - Liquid concentrate that mixes in cold water. No tablets, no soaking, no scrubbing.
- Vinegar-free - Citric acid buffered with food-grade sodium citrate. Phosphate-free, dye-free and fragrance-free.
- Rinses clean - No lingering smell, so your next cup tastes right.
How to use:
- Empty the water reservoir and remove the water filter.
- Pour 2 tablespoons (1 fl oz) of concentrate into the reservoir and fill with fresh water.
- Run descale (brew) cycles until the reservoir is empty.
- Rinse by running three full reservoirs of plain water.
Descale every 3 to 4 months, or when the DESCALE light comes on.
