I had a relative involved with a study on pesticide removal. Unfortunately, unless you're using a wire brush, the pesticide isn't coming off your fruit.
This is what modern, efficient, large-scale farming is all about. We use fungicides, pesticides, herbicides, to exterminate almost every living organism from the vicinity except for the crop itself.
You would almost certainly starve if you tried to eat only things that have been grown without any such chemicals. Most "organic" type of certifications do not blanket prohibit them.
