To maintain a convertible soft top, clean it gently with a product made for fabric or vinyl roofs, remove any green algae or mould before it stains, and reproof it so water beads off and UV damage is kept at bay. Standard car shampoo and brushes do more harm than good. A little regular care keeps the hood looking sharp, waterproof and free of the leaks that ruin convertibles. For a full restore, our convertible top treatment handles it all.
Why soft tops need special care
A soft top is fabric or vinyl exposed to constant weather, so it behaves nothing like painted bodywork. It absorbs moisture, grows algae and mould in damp spells, fades under UV, and loses its waterproofing over time. Treating it like the rest of the car, with ordinary shampoo and stiff brushes, strips the proofing and frays the material. It needs its own routine.
Cleaning the hood safely
Brush off loose dirt and leaves first, then use a cleaner made specifically for soft tops with a soft brush, working gently along the weave. Avoid high-pressure jets at close range and never use household detergents. Rinse thoroughly so no product is left in the fabric, and let the roof dry fully before putting it down.
Dealing with mould and green algae
Green staining down the sides of a hood is algae, and dark spots are mould, both common on cars parked outside or under trees. Treat them early, because the longer they sit the more they stain and weaken the fabric. A dedicated mould and algae treatment lifts them without bleaching the colour. Heavy or set-in growth is best left to a professional soft top treatment.
Reproofing for waterproofing and UV
Cleaning strips some of the roof's water repellency, so reproofing afterwards is essential. A quality waterproofing agent restores beading so rain runs off instead of soaking in, and UV protection slows fading. If your hood has stopped beading water or you notice damp inside after rain, it is overdue for reproofing.
How often to treat a soft top
As a guide, clean and reproof a soft top once or twice a year, and more often if it lives outside or under trees. Catching algae and proofing early prevents the expensive problems, leaks and rot, that come from neglect. We treat fabric and vinyl hoods on all makes across Derby and the East Midlands.
