… pesticide residues are removed by cold water washing.
Here are some other ways people are washing:
Vinegar Soak
Whip up a solution with 10 percent white vinegar and 90 percent water and soak your veggies and fruits in them. Stir them around and rinse thoroughly. Be careful while washing fruits like berries, and those with a thin peel as the solution might damage their porous outer-skin.
Blanch and Peel
Treat your vegetables to warm water for a short while and this should remove any leftover residue. Peeling is another efficient way to remove residue and comes highly recommended especially when there might be some residue in the crevices of the fruit. Also, when cooking with chicken or meat, cut off the excess fat and skin as it could have absorbed unwanted pesticide residue.
