Pollen:
The yellow dust you see in the air made up of small cells from blooming plants and are one of the most common allergy triggers. The pollen from trees are the main concern, vehicles get hit with pollen laced trees that include: oak, western red cedar, elm, birch, ash, hickory, polar, sycamore, maple, cypress and walnut.
Pollen isn't removed by air friction as you drive because it adheres to a surface with microscopic barbs that can attach to even a very slightly uneven surface, and adheres to a natural wax better than a synthetic polymer
As well as being an allergic it is both an abrasive and a corrosive type dust especially when mixed with water and should therefore be removed from paint surfaces as soon as is practicable.
For dry pollen dust use a (California Car Duster) lightly brush the surface using long strokes in one direction only. If the pollen is wet remove with a damp waffle weave towel, to avoid scratching, using as little pressure as possible, again wiping in one direction only.
As soon as is practical, thoroughly rinse the vehicle with a hose and clean water to ensure all acidic pollen is neutralized / removed.
