Let’s find out.

As already mentioned, considering the potential side effect of neem oil consumption, preventing oil ingestion should be your top priority. First of all, you should thoroughly wash all vegetables treated with neem oil in lukewarm water.

The warm water here plays a significant role since oil does not mix well with cold water and the layer of oil remains unaffected. You may also use a mild soap solution for dissolving the oil from the edible leaves and vegetables. Any substance capable of lowering surface tension like soap helps in removing grease and oil. Moreover, rinsing the same with lukewarm water two to three times can remove the layer of oil together with this soap solution.

Things needed for washing neem oil:

Depending on the amount of harvest you want to wash, you may require a bowl of lukewarm water or a large can for effective washing of the vegetables. For instance, if your domestic harvest comprising small amounts of veggies, then you may not need a lot of substances. But if it is a commercially produced large scale yield, then you would definitely have to arrange for more.

You will require running tap water and a bowl of clean lukewarm soap solution for washing off small produce. But a watering hose or can may be required if you want to wash the vegetables before they are harvested. For large-scale plantations, a spray bottle can be used for spraying the warm water directly onto the veggies. Thus, you should be ready with the following things:

  • Bowl: Required only in the case of washing a small harvest
  • Mild cleanser: For removing the layer of oil easily by lowering the surface tension
  • Water: Most important element for washing
  • Nozzle: Needed for adding pressure to the water force
  • Hose: Necessary for transportation of water in large scale washing

Steps for washing off neem oil:

If you don’t want to use soap in edible items, you may skip it. Even though using soap leads to faster and more effective results, warm water can also get the job done.

The next step is to spray the soap solution directly on the vegetables generously and allow them to rest for some time. Lastly, you must rinse the soap with water by thoroughly washing the veggies with water. Allow running tap water time to flow over the vegetables rather than dunking them because the high pressure helps in removing the neem oil effectively.

After following these steps closely, your vegetables are free from neem oil and are safe for consumption. You can eat them raw or use them in a salad without any worries.

Other effective alternatives

Some people are skeptical about the use of soap water when it comes to washing edible things like fruits and vegetables. And if you are one of them, there are several other excellent alternatives to this.

1. Soaking in salt water

It is a proven fact that if you can soak your vegetables in a 10 percent saltwater solution for about half an hour, it will get you rid of most variants of pesticides including neem oil.

2. Soaking in vinegar

Vinegar is yet another remarkable protection against pesticides. A properly prepared mixture of vinegar and water will not only help in the removal of neem oil from the vegetable skin but also some harmful bacteria which may have found their way to the veggies.

3. Soaking in baking soda solution

It is also highly effective in soaking your vegetables in a solution made with 1 part baking soda and 100 parts of normal water. But you should be careful while soaking vegetables with thinner skin in these solutions as the porous outer layer may allow these solutions to seep through the vegetable skin.

This step is very useful for those vegetables with thick skin. To wash off the neem oil from the outer layer, give it a nice scrub with a brush in any of these solutions. This will reduce the chances of contamination up to 96 percent. Allow it to dry out and the vegetables are ready for consumption.
