Vegetables are bleached with a very diluted chlorine although it will crack the skin and make the vegetable look unacceptable. Very controversial way on how you wash vegetables. One of biggest limiting factor is water on brown eld since they don"t have a easy access. You have to get people to haul water to your site.
