Preparing fruits and vegetables at home does not call for a homemade hydrogen peroxide wash. Start with the produce label and established food-handling guidance rather than a chemical recipe. This article does not recommend peroxide for washing food, preserving produce or treating plants.
Start With Clean Hands and Equipment
Keep fresh produce separate from raw meat, poultry and seafood during shopping and preparation. Clean your hands, utensils and preparation surfaces before handling food. Use different cutting boards where practical, and clean equipment between tasks.
Use Running Water, Not a Peroxide Soak
The FDA’s produce-handling guidance recommends washing produce under running water before preparing or eating it, including items whose peel will be removed. Gently rub the surface while rinsing. A clean produce brush can be used for firm items such as cucumbers and melons. Dry washed produce with a clean towel or paper towel.
Do not wash fruits or vegetables with peroxide, household cleaners or disinfectants. FoodSafety.gov advises against chemical washes for produce. More chemicals, a longer soak or a stronger solution are not substitutes for food-handling guidance.
Check the Packaging and Condition
Produce labeled ready-to-eat or pre-washed can be used according to its package instructions without washing again. Remove bruised or damaged portions and discard rotten produce. Refrigerate pre-cut produce and store other perishable items as directed; ask the seller if you are unsure about a particular item.
What “Food Grade” Does Not Mean
A grade description is not a home-use recipe or permission to swallow a chemical. Do not interpret the words food grade as approval to add hydrogen peroxide to a meal or a produce-washing bowl. Commercial processing instructions are not interchangeable with household preparation.
Rinsing is not a guarantee that contaminated or recalled food becomes safe. Follow recall instructions rather than trying to salvage affected produce with peroxide or another chemical.
