I got TSP. I put one Cascade (no phosphorus of course) in one little cavity in the door and filled the other one (smaller) with TSP.
The dishes came out OK, but it wasn’t a heavy load. I looked closer and saw that the smaller cavity was labeled “pre-rinse.”
But even if I put TSP in the other cavity, doesn’t it dissolve right away and rinse away very quickly? I would like it to be released gradually, like the commercial detergent.
The first reason I want it TSP to be there throughout the wash is that I think it will make the dishes cleaner.
The second is that I have read that since cascade removed phosphates, some of the vital parts of dishwashers are going to hell. For example, there are reports of water pumps getting clogged.
I guess the best bet would be a controlled release detergent with phosphates, but the eco-nazis have gotten to the federal govt. of course, and many state govts., and so all the corporations play ball.
I mix my TSP with the detergent with a spoon. I have kept experimenting, and I think they come out better when I used powdered detergent than liquid.
I still can’t believe we have to do this.
