Cascade soap for dishwashers has been around for awhile and I have used this brand in powdered form for some time. I recently decided to give the liquid form of Cascade a try and I am so glad that I did. It leaves the china as well as silverware sparkling clean. Even the pots and pans seem to shine. The soap dissolves quickly and i don't have to worry if the water is hot enough. The light scent of the soap adds assurance that the dishes are clean. Probably the biggest plus of the liquid Cascade is the cap on the bottle. When closed it assures no more spilled soap under the sink and it seems we have less waste from overfilling the soap dispenser. The soap mixes with the water better than the powder and the plates and glasses come out sparkling clean. Even pots and pans seem to be cleaner and I love the fresh clean smell of Cascade. I really haven't taken time to compare the cost of using boxes of soap to using the liquid as I enjoy the convenience of the liquid and feel that the liquid is worth any difference.
