Wipe the vinyl cover with a slightly damp clean cloth. For minor cleaning such as dusting, you don’t need to apply any cleaner to the surface of the cover.
Read the directions that came with the custom cover to find out the manufacturer’s recommendation for cleaning the cover. The instructions are determined by the material the cover is made from and its method of construction. Their instructions preempt any other cleaning instructions.
Soak a clean cloth in a solution of warm water and mild soap, then ring it out and wipe the cover using light pressure to remove stains.
Clean the seams and stitching of the cover, which often picks up dust and dirt. You may need to use a thin piece of plastic or wood to remove any material that has seeped into the groove of the seams.
Apply a vinyl cleaner to perform a deeper cleaning of the vinyl surface. Using only water and soap cleans the surface of the cover but doesn’t condition the vinyl and keep it moisturized.
