Use a shop vacuum cleaner to vacuum up any dirt, dust and sand from the bottom of the Achilles Inflatable Boat.
Fill a bucket with a gallon of cool fresh water and a 1/4 cup of a mild soap, such as liquid dish soap or liquid laundry detergent.
Dip a soft cloth or sponge into the soapy water. Clean the rubber interior and exterior rubber surface of the Achilles Inflatable Boat.
Rinse the soap from the boat with cool, fresh water.
Rub a soap pad lightly over any remaining spots or stains to remove. Dampen a soft cloth with fresh water and wipe away any residue left from the soap pad.
Allow the Achilles inflatable boat to air dry, in a shaded area. Do not leave the boat in direct sunlight.
