When washing the exterior of an aerial apparatus, where should you start?

Starting at the top when washing the exterior of an aerial apparatus is the most effective method for several reasons. Beginning at the top allows gravity to assist in the cleaning process, as water and soap will flow downward, carrying dirt and debris away from the surface rather than moving it around or pushing it into already cleaned areas.

This technique ensures that contaminants and grime do not recoat lower sections of the apparatus after they have been cleaned. As you work your way down, you can address each section thoroughly without risking contamination from previously cleaned surfaces. Additionally, washing from the top downward helps to avoid unnecessary rework, as it streamlines the cleaning process, ultimately resulting in a more efficient and effective wash.

Cleaning strategies that start at the bottom or in the middle may lead to a less thorough job, as debris may be pushed onto already cleaned areas, requiring additional effort to achieve the desired cleanliness.
