Regularly cleaning vinyl seats will help them to stay in excellent condition for an extended period. Vinyl seats in boats and cars need proper maintenance because they are susceptible to mold and mildew due to the porous material. The cleaning method needed for the seats will depend on the stain you are removing from the seats. Once the seats are clean and free of dirt and debris, an application of a vinyl protectant will help to keep your vinyl in extraordinary shape.
Vacuum the vinyl seats to remove dirt and debris. Run the vacuum nozzle between crevices and creases to remove hidden dirt.
Apply rubbing alcohol to a cotton ball. Rub the alcohol directly onto the stain with a minimal amount of pressure. Wash the area with hot water immediately or the rubbing alcohol will damage the vinyl.
Combine 2 tbsp. of dishwashing soap with ½ gallon of warm water. Mix the two together slowly to prevent making many bubbles. Apply the cleaning solution to the vinyl seats, and use a scrubbing brush to remove even tougher stains.
Add ¼ cup of ammonia to 1 cup of water. Place this mixture in a spray bottle. Spray the stained or mildew area with the mixture, and scrub it with a soft bristle brush. Rinse the seats with cold water to remove the ammonia.
Apply vinyl protectant to the seats to keep the vinyl clean in the future. Follow the directions on the package when applying the protectant.
Dry the seats off after cleanings. Use a clean towel to remove moisture from the seats to prevent mold and mildew from forming.
