Wash: A Meta-Analysis
The fruit-and-vegetable-washing debate, settled by the two men least qualified to hold a sponge. Jobs brings minimalism. Gates brings 47 studies, a spreadsheet of log-reduction percentages, and opinions about hypochlorous acid. Somewhere in the middle is actual advice you can use at your sink tonight.

The actual takeaways
| Method | Verdict |
|---|---|
| Cool running water + rub + towel dry | The winner. 30+ seconds under the tap, rub firm produce, dry with a clean towel — friction removes most surface bacteria. FDA-recommended. |
| Baking soda soak (12–15 min) | Best-studied method for surface pesticides: the UMass apple study showed it beats water for thiabendazole and phosmet. Rinse after. |
| HOCl 50–200 ppm | Real chemistry, used commercially for produce sanitation; neutral taste at proper concentration. Home DIY generators: verify concentration with test strips — unregulated. |
| Vinegar soak | Modest effect, leaves flavor residue. Rinse well after. |
| Salt water | Fine for bugs in leafy greens. Otherwise mostly vibes. |
| Commercial veggie wash | Studies show no better than plain water. Expensive water. |
| Soap or detergent | Never. FDA says no — residue, not safe on produce. |
- Berries: rinse just before eating — pre-washing speeds mold.
- Leafy greens: separate the leaves, cold water, then dry.
- Peeling: removes surface residue but also the fiber and nutrients near the skin.
- Drying with a clean towel is a real decontamination step, not a formality.
