Thanks to everyone who posted information about their experiences with the new phosphate free formulations of dishwasher detergent.
Recently, unknowingly I purchased a box of the newly reformulated Cascade and had chalky white film all over the inside of the dishwasher, dishes and silverware after the first use. I realized it was "phosphate free" when I closely looked at the box trying to figure out what happened. I know the problem is the new formulation because I ran another cycle with what I had left of the old product and everything came out flawlessly. My water temperature is about 130 deg F, I use rinse agent, run the water at the tap before starting the dishwasher and use the sani rinse option. Our water is very hard at about 12 to 15 gr/gallon. The phosphate makes a big difference with the hard water.
I went to my local Big-Lots and found they are clearing out the old formula of the great Cascade Complete with Bleach Hydroclean Action. I stocked up. I also found a source of STPP for when I run out of the old Cascade.
Two questions:
1. When I use the STPP, how much should STPP and detergent should I put in the dishwasher? I have a new KitchenAid with the main and prewash cups. I typically fill both cups completely with detergent.
2. Is STPP OK to use in a front loading high efficiency machine? I have a new LG (model WM2050). Again, how much should I use for a normal wash? Should I put it right in the bottom of the tub or with the liquid detergent in the dispenser? Will the STPP harm clothes in any way over time?
Thanks very much.
