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.
Yes, vinegar I’ve heard and I see no reason why dish soap wouldn’t work.
