Some of the chemicals are bonded in a waxy sealer. Gotta bust the seal to get the chems off. Even hot-hot-hot water doesn't really get it all, and on apples, for instance, you can see the residue after a wet wash.

Cain't you taste it on yore apples?!?

Sure, I could buy organic, but the wash is said to remove so much of the chems that it's an affordable option to organic.
