How to Clean Stains From Vinyl Boat Cushions

Vinyl is an excellent material for outdoor furniture because it is strong, durable and weather-resistant. However, vinyl still requires regular cleaning and maintenance to ensure that mold, mildew and other stains are managed. This is particularly true in damp climates or on boats where vinyl cushions are exposed to moisture on a constant basis. If left untreated, vinyl boat cushions can develop mildew and mold stains that are difficult to remove. Fortunately, several methods are available to clean stains from your vinyl boat cushions with little fuss.

Step 1

Dip the Mr. Clean Magic Eraser sponge into warm water and wring it out so it is just damp.

Step 2

Scrub the stains on the vinyl cushion with the Magic Eraser sponge, moving in a circular motion until the stains begin to diminish.

Step 3

Spray your cleanser for marine stains or mold and mildew remover into a rag or cloth.

Step 4

Rub the cloth over the surface of the vinyl cushion, applying extra pressure to the areas with heavy soil. Repeat as necessary.

Step 5

Fill a spray bottle with white vinegar and screw the cap on tightly.

Step 6

Spray the front and back of each vinyl cushion with the vinegar. This will disinfect the cushions, kill any existing mold and prevent the growth of any new mold.
