After spilling a liquid or mopping/steam cleaning, how does blowing a fan on the damp area speed up the drying process?

I know about basic evaporation of water into the air, is it the same concept if the liquid is not water? I was under the impression that heat was what sped up evaporation, not increased airflow.

The liquid in question is probably mostly water.

The blowing air is providing energy, a kick, to the water to evaporate. While heat is part of it, any temperature of water can become vapor. The way to think of it is that air is a sponge. You have a puddle you need to wipe up. If you heat the area, the sponge becomes a bigger sponge (hot air holds more water than cool air). If you blow air on it with a fan, it’s like using more sponges.
