Fruit and vegetable cleaning process

1a. Are most juicing outlets washing / cleaning pre-pressed produce by hand – or is an automated process (partial or entire) being incorporated? 1b. As for automation, what machinery may be purchased to ensure fruits and vegetables are washed in ways consistently meeting / surpassing health department standards?

  1. Have any certain methods or washing solutions compromised the integrity of organic produce?

Thanks everyone! I continue to appreciate all you who so freely offer input. Amazing!
