[Physics] Does fog clean the air of fine dust

Question

When fog forms, the air is usually saturated with moisture. Thus, small droplets form and creates fog. Suspended fine dust can serve as condensation nuclei during the formation of fog.
So my question is: when fog forms overnight over a city, is the air cleaned of fine dust, as the dust particles are now trapped within the water droplets?

Answer 1

only if the fog descends and then one of two things happen: 1: it rains or 2: the fog blows away
