In many households, washing store-bought fruits and vegetables is the norm. While it’s a good practice to remove dirt and harmful bacteria, it may not be enough. Fresh fruits and vegetables pass through various hands before reaching grocery stores and farmers’ markets. Thus, its cleanliness is questionable. Even if it's organic food, it is prone to contamination and dirt.
Since fruits and vegetables are an essential part of a daily diet, they may need more than just tap water to clean them. This is done to remove any residue that may still be left behind. Here are some effective ways to ensure that your fruits and veggies are pesticide-free before you consume them.
List of produce with the highest pesticide residues
- Spinach
- Strawberries
- Kale, collard, and mustard greens
- Grapes
- Peaches
- Cherries
- Nectarines
- Pears
- Apples
- Blackberries
- Blueberries
- Potatoes
The best way to clean your fruits and vegetables
It’s best to wash your fruits and vegetables right before you’re planning consume them. Clean your hands before you start and ensure the sink and utensils you plan to use are also thoroughly clean.
Baking soda
This one won’t fail you, as it is a science-backed way of removing up to 96% of the pesticides. All you have to do is pour 2 cups of water into a bowl and add 1 teaspoon of baking soda to it. Soak your fruits and veggies for 12 to 15 minutes. Gently wash the surface, take them out, and rinse the fruits and flowers in running water.
Vinegar
Vinegar can also be used in place of baking soda. Simply add 1 tablespoon of vinegar to 2 cups of water and soak fruits and veggies for about 5 minutes. Finally, clean them under running water.
Running water
For leafy greens, which pick up visible dirt, soaking in water for a few minutes helps. Wash the surface thoroughly and gently with your hands. Rinse under running water, and repeat the process 2-3 times.
What to avoid
It is best to avoid using chemical disinfectants, soapy water and detergents, as they do more damage than good, making your produce unfit for consumption.
Properly washing produce is one of the most effective ways to reduce exposure to pesticides, as well as bacteria and soil. While no method removes 100% of residues, several evidence-based techniques can significantly lower the levels.
1. The Baking Soda Soak (Highly Recommended)
Research, including studies from the University of Massachusetts, suggests that a baking soda solution is more effective at removing certain pesticides than plain water or bleach.
The Ratio: Mix 1 teaspoon of baking soda for every 2 cups of water.
The Process: Soak your fruits or vegetables for 12–15 minutes.
The Finish: Rinse thoroughly with fresh tap water.
2. The Vinegar Rinse
Vinegar is excellent for killing bacteria and can help break down some surface waxes and pesticide residues.
The Ratio: Use 1 part white vinegar to 3 parts water.
The Process: Soak produce for about 5–10 minutes. This is particularly good for berries (it also helps them last longer in the fridge).
The Finish: Rinse well to remove any lingering vinegar taste.
3. The Salt Water Soak
A simple saline solution can also be effective, especially for green leafy vegetables and cauliflower where pests and residues may be hidden in crevices.
The Ratio: 2 teaspoons of sea salt per 4 cups of water.
The Process: Soak for 15–20 minutes.
The Finish: Rinse with clean water.
Important Tips for Specific Produce
Firm Produce (Apples, Carrots, Potatoes): Use a clean vegetable brush to scrub the skin under running water. This physical friction is very effective.
Leafy Greens (Spinach, Cabbage): Remove and discard the outermost leaves first, as they often contain the highest concentration of pesticides.
Soft Fruits (Berries, Grapes): These are delicate. Place them in a colander and spray them with your cleaning solution, let sit for a minute, and then rinse gently.
Peeling: If you are deeply concerned about a specific fruit (like a non-organic apple or cucumber), peeling is the most certain way to remove surface pesticides, though you will lose some fiber and nutrients found in the skin.
What to Avoid
Commercial Produce Washes: Most health organizations, including the FDA, state that these are no more effective than plain water or baking soda.
Soap or Detergents: Never use dish soap or laundry detergent. Fruit skins are porous and can absorb the chemicals in the soap, which are not safe for ingestion.
A Note on "The Dirty Dozen"
If you are looking to prioritize which items to buy organic versus conventional, the Environmental Working Group (EWG) releases an annual list called the "Dirty Dozen." These are the crops that typically test highest for pesticide residues, such as strawberries, spinach, and grapes. Conversely, the "Clean Fifteen" (like avocados, sweet corn, and onions) usually have very low levels of residue.
