As per our customers request, we customized our cleaning system for this box cooler job. We lifted the box coolers into the engine room where they were treated with MultiGel to dissolve the marine growth. Then we waited until the sea chests were painted and dry before lowering them down. Then we high-pressure washed them using our angled nozzle to reach between the pipes. Doing it this way saved the trouble of hp-washing inside the engine room.
