How Do You Remove Mildew From Boat Seats?

To remove mildew from boat seats, clean the affected areas with baking soda and a solution of white vinegar and water. Tough mildew stains can be removed using a chlorine bleach solution. Typically, the boat seats can be cleaned in about an hour and may take up to a day to dry.

  1. Clean with baking soda

    Sprinkle a small amount of baking soda on each seat, and then scrub the seat gently with water and a soft brush to remove any excess debris. Do not rinse the seats.

  2. Wash the seats with vinegar

    Mix a solution of half white vinegar and half water in a spray bottle, and spray each seat with the mixture. After the vinegar and baking soda stop bubbling, put on gloves, and wash the seat with a soft cloth or brush. Rinse each seat thoroughly.

  3. Wash stains with chlorine bleach

    If mildew stains are still present after washing with vinegar and baking soda, mix 1 cup of bleach with 9 cups of water. Wearing gloves, apply the solution to the stained areas with a soft cloth, and then rinse the area with cool water.

  4. Allow the seats to dry

    If possible, dock the boat in a sunny location to promote faster drying.
