This review is from: De'Longhi Natural Descaler for Bean to Cup Machines, 2 x 100 ml (Kitchen & Home)
You really have no choice but to use this product which does exactly what is required and is recommended by the machine manufacturers. handy dispensers so easy to use. Worth using the used liquid to descale your kettle or other household items after prime use before discarding.
