What type of equipment is used to decontaminate the exterior of a boat?

A pressure washer is the most effective piece of equipment for decontaminating the exterior of a boat. It uses high-pressure water jets to dislodge and remove debris, organisms, and contaminants that may be present on the boat's surface. This method is particularly beneficial because it can reach areas that are more difficult to clean manually, such as the hull and any crevices.

While other options, such as a hose or a sprayer, can be used for cleaning, they do not provide the same level of power and thoroughness as a pressure washer. A hose offers water flow but lacks the high pressure necessary to effectively remove all potential invasive species and contaminants. A bucket might be used for manual cleaning tasks, but it requires more effort and does not guarantee comprehensive decontamination.
