“Does a great job for less cost than the Miele tabs. Leaves no residual flavors after use.”
“We have been buying this brand for our Breville espresso machine for years. It does do a good job in descaling the machine. I notice it in how well the steamer knob works after using it. My machine is too expensive to experiment with cheaper brands.”
