I use potassium permanganate crystals dissolved in water (so its a pink color) to wash fruits and veggis and then rinse it with water.
Mostly for bacteria (e coli, salmonella etc).

You cannot wash pesticides away. They are integrated with the plant.

I have always rinsed produce well in plain water. So far so good.

Produce wash washing liquid?

Does a simple rinse under the faucet do the job or is there a better method to ensuring pesticides are washed away without damaging produce?
