Wash with warm water
Though pesticides are applied on the leaves and stems, a considerable amount of it also gets accumulated on the fruits and vegetables as well. A thorough wash in warm water can help to get rid of these toxins before they are consumed. Very hot or very cold water will not help to remove the entire residue from the produce. Instead use warm water to clean it.
Rinse them in salt water
There are some popular fruits and vegetable that falls under the dirty list, for having excess chemicals. Soak the vegetables and fruits in a large bowl of water and add half a teaspoon of salt in it. Let the produce sit in the solution for a couple of minutes and then rinse them again with normal clean water. For a better option, store bought vegetable and fruits washers such as Vegfru wash etc can also be used. But the most important thing to be remembered is to always wash the produce before cooking, no matter where they come from.
Use dilute vinegar solution
Most pesticides contain organophosphates, carbamates, organochlorines, sulfonylurea, pyreathoids, etc which is potentially harmful for the body. The presence of these contaminants is not just superficial but they also get absorbed by the peel as well. There is no need to buy fancy vegetable and fruit cleansers from the stores when it can be easily prepared at home. Just take about a teaspoon of vinegar in a large fruit bowl and dilute it with water. Leave the fruits and vegetables in it for some time and then wash them under tap water.
