Research shows an alkaline solution can remove more surface pesticide residue than water or bleach, though it does not eliminate chemicals that penetrate beneath the peel.

A study examining methods to reduce pesticide residues on fruits and vegetables found that soaking produce in a baking soda solution for several minutes significantly improves removal of surface chemicals compared with common washing techniques.
Researchers at the University of Massachusetts, Amherst reported in the Journal of Agricultural and Food Chemistry that a 12- to 15-minute soak in a baking soda and water mixture removed the majority of detectable surface pesticide residues. The findings compared three methods: rinsing with tap water, soaking in a dilute bleach solution commonly used in post-harvest processing, and immersing produce in a baking soda solution.
According to the study, a brief rinse with tap water resulted in limited removal of pesticide residue. A short soak in a bleach solution reduced some contamination but left measurable amounts behind. The baking soda solution, by contrast, removed nearly all surface-level residues tested in the experiment.
Researchers attributed the results to the alkaline properties of baking soda, which can break down certain pesticide compounds while also helping dislodge residues from the surface of produce. The study noted that this chemical degradation distinguishes the method from simple rinsing, which relies primarily on physical removal.
The analysis also identified important limitations. Some pesticides can penetrate beyond the outer layer of fruits and vegetables within a short period of time. In controlled testing, a portion of one commonly used fungicide moved beneath the peel within approximately 30 minutes of application. Once inside the fruit, these compounds could not be removed through washing.
Researchers concluded that peeling may reduce exposure to those internal residues, though doing so can also remove nutrients concentrated in the skin.
The study examined two types of pesticides: one that primarily remains on the surface and another that can be absorbed into plant tissue. The difference between these compounds helped explain why washing methods vary in effectiveness.
Health researchers have long examined links between pesticide exposure and a range of outcomes, including neurological, endocrine, and cancer-related effects. The study did not assess health outcomes directly but emphasized that reducing exposure where possible may be beneficial.
The findings suggest that preparation methods can influence the level of pesticide residue remaining on produce. A baking soda solution—commonly prepared using approximately two teaspoons per liter of water—was identified as an effective approach for surface cleaning. Researchers also noted that combining acidic substances, such as vinegar, with baking soda neutralizes the solution and reduces its effectiveness.
While washing cannot eliminate all forms of pesticide contamination, the study indicates that certain methods can significantly reduce residues present on the surface of fruits and vegetables.
