Insecticide on Broccoli
I sprayed my broccoli with an insecticide. How do I clean it before cooking it?

Most insecticides have a time period that they break down in. Simply waiting that time period will cause it to go away. The time period varies depending on the type you used. You can also soak the vegetables in water for a few hours and discard the water.
In the future, you may want to consider using a human consumable insecticide. We recommend neem oil. It will kill bad bugs but has no adverse effects on people and pets. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
