Dishwasher power with TSP can still be bought for commercial applications. Any idea what the difference is between STPP and TSP?

TSP leaves a mineral crust. Either stick with STPP or get one of the many rinse aids on the market, like Lemi Shine, the Walmart house brand, etc.

Well, STPP is food grade. TSP is much harsher and can be corrosive to your appliance.

Detergents with phosphates are difficult to find depending on where you live, and overpriced. Usually you have to buy the commercial stuff.

One plus of buying STPP on its own is that you can add it to your washing machine as well as your dishwasher. I don’t think there are any clothes detergents on the retail shelf with phosphates in them.

Lack of phosphates also causes crud to build up in your dishwasher, hurting an already inefficient device thanks to the EnviroTards. As well as shortening the life of the appliance.
