Domestic Appliance Descaler is a formic acid-based, food-safe descaler for use on appliances where scale build-up could present a problem. It is most commonly used in kettles, coffee machines, steam irons and showerheads, please ensure you are in a well-ventilated area when using this product as formic acid has quite a sharp odour which can linger.
Full usage instructions can be found on the label and on the technical data sheet below.
N.B. Domestic Appliance Descaler should not be used in central heating systems, visit our Plumbing and Heating page for help instead.
