Have been using it for a while and haven't noticed any problems - well, other than a slight green aura eminating from everyone living in the house, but that means we could get rid of the night lights. Given there's a couple of rinse cycles after the wash cycle, I'm not too worried about it.
I also found a couple of sources for STPP. Curiously enough, it comes in three grades, the highest being food grade, where it's used as a seafood preservative! Will see how that compares to TSP.
Last time I looked all they had was the fake stuff, we both live in HOU so I'll check around some more.
That's what I was going to do too, mix it in gallon containers with tight lids.
For almost a big box of detergent now I've used the following combination of procedures with flawless results.
#1. Mixed ONE CUP of TSP with a 75 oz box of Great value power from wal-mart
#2. only fill the cups in the DW about half full
#3. Add one cup of white vinegar to each load
#4. set the dw to "heated wash" even though i run my water heater at 140 and it's about 10 feet away.
I mixed the TSP with the entire contents of powder in a large bowl, with a large serving spoon, then cut a cross shaped slit in the top of the detergent box, and put it back in with a kitchen funnel. The box can then still be used as designed.
ok, where do you get this proposed "STPP" ?
If it left a residue, it's not likely they would shine. And THAT is what we've been missing. Shine.
There's someone on eBay selling 10lb bags of the stuff for about $40 including shipping. This place also has it for about the same price:
Have no idea how reputable either source is, of course.
Did some further research. It looks like both TSP and STPP have been used as binders for dishwashing and clothes detergent. STPP is a complex phosphate that has lower alkalinity and some other beneficial properties that made it the preferred choice in recent years.
I did a test load yesterday with about a half a tablespoon of TSP in addition to the regular dishwashing stuff. The one thing that was different was that baked on chocolate cake residue that previously had to be scrubbed off by hand after the dishwasher failed to remove it was almost totally gone.

And apparently also can be bought in food grade. TSP sales are illegal here, so I figure as long as I have to order it I might as well get the most appropriate thing.
where is "here" ?
