Hot running water is actually quite effective. Some solid and oily toxins are considered technically insoluble in water since so few milligrams will dissolve in a liter. Unlike familiar things that are obviously soluble in grams like salt or sugar. Now the pesticides are developed to be highly toxic in milligram amounts, but the advantage is that there is likely only to be a few milligrams on the farm produce that needs to be washed off. Solubility is a function of solvent temperature and volume, so the hotter and the greater number of liters or gallons, often astronomically more of an "insoluble" material can be taken up into a solvent compared to the very minuscule amount soluble when cold. Naturally thorough flushing and/or repeated rinsing with fresh hot solvent will be more effective than a single bath, since the first bath sees the highest concentration of solute. Which can re-deposit upon evaporation. I'm sure people have not thought it was that bad and have occasionally eaten something like an unwashed grape or strawberry, or even quite a number of them whether focusing much awareness on it or not. Take fruit from that same batch and run it under good amounts of hot water and see if you can taste the difference too. Carefully using an appropriate vegetable brush is a good idea as well.
