@Jerrod. Finish Powder (american, phosphate free) is a very weak detergent.
For years(Finish) called Electrasol produced nothing but, weak, Chlorine Detergent with a 3-4 Phosphorus, while Cascade was producing an Enzyme Powder with 7 percent Phosphorus.
Now, they produce a sorta weak, but functional powder, with 40% Washing Soda (weak, but functioning water softener) and a combination of 10% Sodium Percarbonate (Oxygen Bleach action, for Coffee Mugs, and Tea Stains), and 1% Enzyme. Basically, it'll dissolve through a little bit of Food, but, it's not going to pull of a Miracle like A lasagna Pan..
But.. What's intresting is, a Company called "Huish Chemical" out of Utah, is producing a really, good store (private label brand) Powder for Walgreens,Walmart,Target,Kmart, and a bunch of other stores I'm too lazy to list..
Anyway, there formulation, is Washing Soda + Sodium Citrate, so, you basically get the power of Washing Soda, and Lemon Juice Salt (very similar to LemiShine, however, unlike Lemishine, This salt doesn't kill the Enzymes. But, not only does it have a better water softener, it has almost double the formulation of Enzymes, and it also has the added benefit of Oxygen Bleach (Tubberware Sparkling Agent

)
The only thing, horrible, is there private label knockoff Cascade Pacs. They have a blue film cover on them, instead of the liquid Cascade uses, and this film can slowly discolor your plastic ware, and dishwasher tub..
Obviously though, If you like the Powder, I suggest sticking with it, as it works good for you. However, if your looking for something a little bit better, maybe you'll like my advice
