I love my Dishmaster and always use the Dishmaster soap.
I ordered the liquid and have more than once. I have had a dishmaster for years and let's just say they don't make them like they used to, nut we love the look and so we are on the hook. The soap works and is the only soap you can use on these units, however the price plus shipping is a bit much. I would be very helpful to offer free shipping.
Love the dishmaster faucet. Wouldn't have anything else
Have tried other soaps but as the directions say, use ONLY soap specifically designed for the unit. Just like knock off printer ink---it clogs the system. NOT GOOD!
