Not quite PB...
So, this morning, I had a load ready to go, and thought why not try it out? Sadly, I recognized that I'm actually living a somewhat healthy lifestyle (not that I actually would do, LOL) and there is not one thing in this house that could be used as a substitute for PB.
So I used 2 glases, one tall, one shorter, both covered in toothpaste, the shorter sprinkeled with choclate drink powder, dried in by spending 30sec in the microwave and 1 1/2 minutes with our hairdryer.
That load in the bottom rack wasn't blocking the spray a lot, but at least a bit.
Cycle was Auto, store brand tablets (~30% phosphates).
Everything came clean, except for a plastic cup that flipped over and accumulated the drink powder.
Sorry for the bad lighting, it was early and my tablet has no flash.
Not a comparabel test, but worth a try.
