And truthfully, what I messed up in the first video was not getting into the nuance of water hardness and detergent amounts.
People who follow the directions on powder to "fill cups completely" are going to be in for a rough time if they have soft water. I didn't get into that, so people started using powder, used too much, and had worse results.
So I went further, showed how you can actually get away with very little detergent, which imo is yet another reason to prefer powder.
