Volkswagen manufactured the Cabriolet from the mid-1980s through the mid-2000s. The earlier Cabriolet models were essentially VW Rabbit convertibles, while the later Cabriolet models were VW Golf convertibles. Replacing a convertible roof can cost hundreds of dollars, so maintaining the top can extend its life and save you money. Part of this maintenance involves routine cleanings of the roof. You must take care while doing this, however, as you can damage the roof.
Vacuum or wipe away any debris on the roof.
Rinse the top thoroughly with cold water.
Wash the roof with a cleanser or auto shampoo that is not detergent-based and does not contain bleach. If possible, use a cleanser recommended for cleaning canvas. Scrub the canvas with a soft scrub brush, wiping it gently on the canvas.
Rinse the roof thoroughly with water to completely remove the cleanser. Wash the roof again if it's still dirty.
Dry the roof by blotting up the water with a synthetic chamois or microfiber towel.
