Steam cleaning vessels involves using high-pressure steam to clean and sanitize the interior and exterior of boats or ships. This process effectively removes dirt, grime, algae, and marine growth from surfaces. Steam cleaning is an environmentally friendly method, as it typically requires no chemicals, and it can be used to clean various parts of the vessel, including hulls, decks, engines, and interior spaces. The high-temperature steam not only cleans but also disinfects, making it a valuable technique for maintaining vessel cleanliness and preventing the spread of contaminants.
