Has anyone tried boosting non-phospate DW detergent w/STTP

I've had good results in the past with Wal Mart dishwasher detergent until last week...new formula with no phosphates. It's awful! I had to go out and buy Finish to rewash the load.
 
I make an exception for ALL my cutting knives. None of them go into the dishwasher. It's bad for them, as well as the potential for damage to the dishwasher racks that you pointed out.

The high heat of a modern dishwasher (the Bosch can heat to 161F) will dull the edge on a good knife. Additionally, the heat can separate the handle from the tang, or at least warp the handle. I also handwash most pots and pans. They either take up too much room in the DW or they have features that would be damaged by the DW process.
 
I was trying to say, when one HAS a DW and NEVER even one single item is hand-washed, then perhaps there is a fear of loss of appendage.............

:-)

Of course I'm more joking than anything else. But, I have seen so many DW- users attempt to put stemmed glasses in horizontally. Occasioanlly I mention that a nice chunk of glass in the pump can kill a machine faster than sabotage.
 
Thank you, westyslantfront

When you say something, I've learned to listen. And so in agreement with you about the anti-phosphate movement. It seems like another feel-good issue that won't accomplish anyhting useful for the environment but will make our lives a little more difficult.
 
plain TSP

Does anybody know is plain tsp works in dishwasher or washing machines. At Ace hardware they sell "lundmark tsp". The employee says it's the real thing, because it does not say "substitute" on the label. I bought some and it makes no difference in the washer. I am either using too little or it is fake. Do they only sell tspp at chemical supply stores? The water at my house is so hard that a can put Palmolive in the dishwasher and absolutely no suds will appear.
 
Probably you'll have to go to a chemical supply house to get STPP.

TSP would not work very well in a washing machine. And with very hard water, it might cause problems with your dishwasher as well.

I would recommend adding about 30% by weight STPP to laundry or dishwasher detergent.
 
Thanks for the advice

Sometimes I use glass magic in the dishwasher. I started doing that because my kids saw me using hydrogen chloride in the dishwasher, and wanted to do the same (mommy does it). Glass Magic is 20% phosphate, 80% ???. At $5 a small box, its outrageous. I am glad to find out about tspp from this thread. I think it would be better on the environment to use a little tspp, then to use 3X detergent and twice to water to get the dishes clean. In the desert algae buildup is not a problem, conserving water is.
