You may have heard of people putting their produce in vinegar baths to remove pesticide residue. While this may seem like some new health fad, there’s a lot of science to back this technique up.
Indeed, a recent study out of America’s Test Kitchen found a combination of vinegar and water was the most effective way to clear germs from produce. According to testers, it’s best to use a ratio of one part vinegar to three parts water.

You should never use dishwashing detergent to clean fruits or vegetables. While these cleaning products get rid of germs, they will remain on your onion after you wash away the suds. Consuming soap can have serious adverse effects on your health, so please never put it on your food.
Also, please never use bleach to get rid of pesticides on your produce. Like soap, bleach residue will stick to your produce and make them toxic to eat.

Let this mix sit for at least 12 minutes before removing your produce and washing them with cold running water. Be sure to dry your produce thoroughly before using them.
If you don’t have the time to give your onions a baking soda bath, then you might want to keep an Arm & Hammer produce spray bottle nearby.
