Plain running water is the only method the FDA recommends for washing fruit — soap, detergent, and commercial produce wash are all explicitly advised against.
A quick rinse under the tap handles the routine job, and it does it without leaving anything behind on the skin. Soaking fruit in baking soda or vinegar can pull off more pesticide residue than water alone, but the size of that gain depends on the chemical and the produce, and it comes with real trade-offs in taste, texture, and time.
Here’s what the official guidance actually says, what the research shows about the two popular soaks, and which method fits your kitchen.
What Does the FDA Recommend for Washing Produce?
The FDA’s consumer guidance is to wash produce thoroughly under plain running water before preparing or eating it, and it states plainly that there’s no need to use soap or a produce wash.
Soap, detergent, and commercial produce wash are all on the agency’s do-not-use list. The reason is physical: produce is porous, so soap and household detergents can be absorbed into the flesh even after you rinse, and that residue can make you sick. The same caution applies to home-grown fruit, and the USDA NIFA guide to washing fresh produce echoes it, adding bleach solutions to the list of things that should never touch your food.
Commercial produce wash gets a specific mention because its safety and effectiveness have not been evaluated or standardized. You are paying for a product the FDA does not recommend using.
Technique matters as much as the method. Rinse whole fruit before you cut it, not after — washing before cutting keeps surface contaminants from transferring to the flesh your knife exposes. Firm-skinned produce benefits from a scrub with a clean brush under the running water. Dry with a clean towel afterward.
Does Baking Soda or Vinegar Beat Plain Water?
Both soaks can reduce more pesticide residue than a tap-water rinse, but neither eliminates it, and the advantage varies widely depending on the pesticide and the fruit.
Those are medians across many different studies and chemicals — not guarantees for the apple in your fridge.
| Method | Median Residue Reduction | The Trade-Off |
|---|---|---|
| Tap-water rinse | 30.2% | Fast, FDA-recommended, zero effect on taste |
| Tap-water soak | 33.7% | Roughly the same result as rinsing, with more waiting |
| Baking soda soak | 50.9% | 15-minute wait; requires a rinse afterward |
| Vinegar soak | 54.2% | Can leave a vinegary taste and may soften texture |
| Commercial produce wash | Not standardized | Not recommended by the FDA; safety untested |
| Peeling | Often higher than soaking | Removes edible skin plus some nutrients |
| Soap or detergent | Never use | Residue absorbs into porous produce and can cause illness |
How Do You Actually Do a Baking Soda or Vinegar Soak?
Two things get skipped constantly. One is the rinse after soaking — a soak without a rinse leaves the solution on the fruit. The other is the vinegar taste, which USDA NIFA notes may also affect texture. Soaking berries that long turns them to mush.
Peeling deserves an honest mention. It can be more effective than soaking for residues on or near the skin, and one article citing study findings notes baking soda did not fully remove residues that had penetrated apple peel. The cost is the skin itself, along with its fiber and nutrients.
For everyday fruit, plain running water remains the safe, simple default. If you want the extra reduction, a 15-minute baking soda soak is the easier of the two to live with.

Common Questions
Is it worth soaking fruit in baking soda every time?
For routine washing, no. Water alone is the official baseline and takes seconds. A baking soda soak makes more sense when you want the extra reduction on smooth-skinned fruit like apples, and you have 15 minutes to spare. Peeling or scrubbing accomplishes similar goals with different trade-offs.
Can vinegar damage fruit texture?
Yes. USDA NIFA notes vinegar washing may affect texture and taste. Berries and other soft produce are most vulnerable, and a long soak makes them break down quickly. If you use vinegar, keep the soak short, rinse thoroughly afterward, and stick to firm produce where texture holds up.
Should I wash fruit before or after cutting it?
Before. Rinsing whole fruit first keeps surface contaminants from transferring onto the flesh your knife exposes. Once cut, the interior is no longer protected, and washing after cutting spreads whatever was on the skin into the edible part. Wash, dry, then cut.
