Opened a new box of detergent (kudos to those who make their own) and I always mark a line on the cup with a permanent marker. While I was doing so, I was thinking about how the manufacter makes the cup much bigger than the box recommends you use and that's for extra large loads. They really only recomend half the cup for a regular load. We all know to use a quarter or so of that cup but how many people just dump in a full to the top cup and don't even think about it. And why make the cup so big?? Got me wondering what other products encourage you to use more than you really need.
