I kind of assumed that a person would have already washed the pots before disinfecting....that's what I do. Sorry I didn't spell it out in my post.
I am reminded of my grandmother washing her laundry. She would first wash the clothes, then rinse, then put them in a bleach solution to disinfect them...then one more rinse. Lots of water, but the clothes (and the clay pots) are clean and disinfected.
