After buying fresh produce at the market we wash everything in a bucket using a water and baking soda solution. If there's a lot of dirt, we scrub them with a brush. The mechanical rubbing action and rinsing is very good at removing contaminants. Then finally, we rinse them off with fresh running water running our pressure sprayer (to conserve water, pictured above) and let them dry in the sun. They need to be completely dry, otherwise they may rot faster (moisture accelerates rot).
Washing produce in baking soda prevents foodborne illness and substantially reduces exposure to pesticides, it is more effective than using a vinegar solution (because it needs to be used full-strength, and that can get expensive). This washing technique is the same for fresh greens and fruits, although for berries it is best to wash them right before eating them.
