Today I did a load of handwash that had been handwashed last week.

Much, much different.

Wash water got dirty, but not the murky pukey grey of the first wash. It only took 2 rinses to get the water clear. (clear, not colorless; there is some dye coming out in the rinse)

Seriously, I'm going to do double rinses when I get my washing machine. What an education this has been!
