Descaling removes the mineral scale buildup that forms on the heating element of all coffee equipment.

Dezcal is very easy to use! Just dissolve 1 packet of descaler powder into 32 ounces of warm water; add the solution to the water tank of the machine; turn the machine on and run the brew cycle; and discard the solution. Rinse with clean water several times and you're done! Note: this product is not meant to clean a coffeepot. It is a descaling product for coffee machines only. No returns.
