From Kathy at DIY Life:
After we bought our new high-efficiency washing machine, I was warned by a few different people not to use too much detergent. High-efficiency washers use less water and require less detergent to do their job (hence, the efficiency.) I didn’t give it too much thought, though. What’s the worst that could happen?
Then one day I went out walking in one of the torrential rainstorms the South is so famous for. When I got home my jeans were drenched, and I noticed something curious: a row of white suds had formed above each knee. I realized that my walking action had agitated the denim and brought trapped, excess detergent to the surface. I had to wash my clothes with no detergent just to get rid of the embedded soap.
