Most produce advice falls into two camps: rinse it under the tap and hope, or soak it in something that promises to strip away every trace of pesticide. The honest answer sits between them, and it depends a lot on what you are washing.
What you are actually removing is three things: soil, whatever has been handled by other people between the field and your kitchen, and surface pesticide residue. Plain running water plus friction handles the first two well. The third is where the specialty rinses make their claims, and where one cheap kitchen staple has real evidence behind it.
This guide covers the method that works for most produce, the things that need different handling (berries, leafy greens, firm-skinned items you peel anyway), and the two things you should never wash produce with.
What You'll Need
- A colander: The single most useful piece of equipment here. It lets water move around and past the produce instead of pooling, which is what does the actual cleaning.
- A soft vegetable brush: For anything firm-skinned: potatoes, carrots, melons, squash. Friction removes more than water pressure does. A clean brush kept just for produce beats using your fingers.
- A surface for drying and prepping: Washed produce has to drain and then get cut somewhere. A ROO Mat gives you a wipe-clean silicone surface next to the sink for that handoff, and the pouch takes the tops, stems, and trimmings straight off the board as you go.
How to Wash Fruits and Vegetables, Step by Step
Wash your hands first
Twenty seconds with soap before you touch the produce. It sounds like a throwaway step, but hands are the most common way anything gets onto food between the shop and the plate. Skipping this makes the rest of the washing partly pointless.
Rinse under cool running water, not in a standing bowl
Running water carries dirt away. A bowl of standing water just redistributes it across everything in the bowl. Hold the item under the tap and turn it so every surface gets flow. Twenty to thirty seconds per item is plenty.
Add friction for anything firm
Potatoes, carrots, cucumbers, melons, and winter squash all benefit from a scrub with a brush while the water runs. The rubbing is doing more work than the water. For melons, scrub the rind even though you are not eating it, because the knife carries whatever is on the outside straight through to the flesh.
For berries and leafy greens, soak briefly instead
Delicate produce falls apart under a running tap. Put berries in a colander and dunk the colander into a bowl of cold water, swirl, and lift the colander out so the grit stays behind. For leafy greens, separate the leaves first, then swirl them in a big bowl of water and lift them out rather than pouring the whole thing into a colander.
If you want to reduce pesticide residue, use baking soda
A 2017 University of Massachusetts study published in the Journal of Agricultural and Food Chemistry soaked apples in a baking soda solution, roughly a teaspoon per two cups of water, and found it removed more surface pesticide residue than plain tap water or a bleach solution. Give it 12 to 15 minutes, then rinse thoroughly with plain water. The caveat the study is clear about: it works on surface residue, not on anything that has moved into the flesh.
Dry it before you store it or cut it
Pat with a clean towel or spin greens in a salad spinner. Drying removes some remaining surface bacteria along with the water, and it stops the produce going slimy in the fridge. Wet produce also skids under a knife.

Produce is porous and absorbs soap residue, which is not meant to be eaten and can upset your stomach. Food safety agencies specifically advise against soap, bleach, and any household cleaner on produce. Water and friction, not chemistry.
It feels efficient and it shortens the life of almost everything. Moisture accelerates spoilage. Wash produce right before you use it, with the exception of leafy greens, which store fine if you dry them completely first.
Avocados, melons, citrus, and squash all get cut through the skin. Whatever is on the outside rides in on the blade. Wash the outside even when you have no intention of eating it.
One dirty item contaminates the whole sink of water, and the sink itself is rarely as clean as people assume. Use a bowl or a colander, and change the water between batches.
Upgrade Your Prep Workflow: The ROO Bundle
Washing produce is only half the job. The other half is the wet, slippery handoff from the colander to the knife, which is where a board slides and a cucumber rolls off the counter. The ROO Mat grips a smooth counter so the board stays where you put it even with wet hands, wipes down in seconds when you are working through a sink full of produce, and its built-in 7-cup pouch takes the stems, tops, and peels as you trim them. The Bundle pairs it with a 13.75" x 9.75" rubberwood board and a reusable storage bag.

Frequently Asked Questions
Is it better to wash fruit in vinegar or baking soda?
Baking soda has better evidence behind it. The 2017 UMass study found a baking soda soak removed more surface pesticide residue than a bleach rinse or plain water. Vinegar is often recommended for bacteria rather than pesticides, and it can leave a taste on delicate fruit.
Is Dawn dish soap safe to wash vegetables?
No. Dish soap is not formulated to be eaten, and porous produce holds onto the residue. Food safety guidance is consistent on this: no soap, no detergent, no bleach. Running water and friction.
How do you wash strawberries?
Leave the green tops on so water does not get inside, put them in a colander, and dunk the colander into a bowl of cold water. Swirl, lift out, and dry gently. Hull them after washing, not before, and wash them the day you eat them rather than the day you buy them.
Do you need to wash pre-washed bagged salad?
It is not required, and re-washing it in a home kitchen can introduce more than it removes if your sink or colander is not spotless. If you would rather wash it anyway, use a clean bowl of cold water and dry it thoroughly.
Does washing remove all pesticides?
No. Washing removes surface residue. Some pesticides are systemic, meaning the plant takes them up into the flesh, and no amount of rinsing reaches those. Washing is still worth doing for dirt, handling, and the residue that does sit on the surface.
Cool running water, a bit of friction, and drying properly afterward covers most produce. Add a baking soda soak when you specifically want to reduce surface pesticide residue. Skip the soap, skip the full-sink soak, and wash things when you are about to eat them rather than the moment you unpack the bags.
