Are the white spots wooly and white? If so, there are Wooly Aphids, and Aphid drip a near transparent excrement, that if it lands on a windshield, dries like clear filmy spots.
That residue on other plants and hard surface can provide growth to black sooty mold too.
You did not say how the tree dripped. So this is what came to mind.
Is that possible?
You could go to a local garden supplier and ask for a systemic insecticide to water into the root system - may be available.
