I have a theory about these new detergents, including all the fancy new Cascade dishwashing products. You know how most of the products (like cereal, as one example) just reduce their size/volume and change the same amount of money?
Well, I'm convinced that the detergents do it a little differently. I think that they have made their base products less effective--in common English, watered them down! The base dishwashing products are near-useless anymore. I have to wash a dish three times before all of the grease is gone, and a simple run through the dishwasher is useless unless I've "washed," (not to be confused with rinsed) the dish first.
I have a new Whirlpool dishwasher, so it can't be blamed on the new dishwasher like I used to blame it on the old dishwasher.
So what has changed? Why the need for all the "new and improved and more costly" products if we lived just fine with the base products all these years. The need, of course, is a growing corporate profit, and the only way to do this is to convince us that we need the more expensive products. How to convince us? To make the old (base) products less effective.
It only makes sense, if you think about it. Anyway, that's my theory.
