So, I've done it again. I assumed that all of the pieces for my boyfriend's meat grinder were stainless steel and I threw them in the dishwasher. (We've had it for a while, but this is the first time I've used it since we moved into a house with a dishwasher.)
The tray, blade, and plate came out fine, but the bigger pieces were apparently a coated aluminum. They came out with the black residue all over them.
He read online that if you clean all of that off, let it dry, and it turns black again, throw it away. Does this mean if it DOESN'T turn black, it's safe to use? Or do I need to buy him a new grinder? :(
