Daconil doesn't wash off my fruit

Hi guys, I combat powdery mildew and other funguses constantly.

When I use daconil, it leaves spots on the fruit.

When I harvest and wash the fruits, the spots seem to disappear. But when I dry the fruit the spots reappear. The tomatoes are too soft to scrub the spots.

Does anyone else have this problem, and if so what do you do?
