Best Detergent For A Classic KA DW
Hi Nick, I order to make a recommendation it is helpful to know several factors at your home.
What model DW do you have, and what cycle do you use ?
How hot is your water and how hard is it ?
How dirty are your dishes going into the DW ?
In general the tablets are better for the DW, they are not as aggressive so they don't damage the racks, pump seals, the porclean interior as the old phosaped powders can. However some tablets can foam too much and cause loss of washing pressure and possible leaking out under the door.
