I find it mildly upsetting that I can make my blender clean by putting some soap & water inside, and then turning it on.
If I put soap and water into the fridge and close the door, it doesn't get clean. It just makes a mess. If I put soap and water into the air fryer and turn it on things turn out even worse.
I can't clean my kitchen knife by mincing up a bar of irish spring. I soap up my frying pan and then put it in the sink, not on the stove. If I put dish detergent into the coffee maker and run it, that is going to improve neither the coffee maker nor the coffee mug.
Something just seems fundamentally wrong about the blender situation. Paradoxical. It is an inversion. Like digging up to get out of a hole.
I think the thing that I don't like isn't necessarily that I'm blending soap. What gets me is the implication that during its normal operation, I'm using the blender to clean food.
