Wash my lettuce in a diluted hydrogen peroxide solution.

I was just thinking about a 'wash' that would be effective.
Dilute bleach? impart an odor that would destroy using it?
Might do a little testing.

I think much less than hydrogen peroxide would be effective.

I’ve washed questionable produce in a bath of warm soapy water in the kitchen sink and then rinsed. That will kill or wash off any e-coli or other harmful pathogens for the most part.

White vinegar also makes a good harmless “disinfectant” for product.
