Step 2: Remove Debris

So, start off nice and easy brushing off any loose debris. Leaves. Mud. Dirt. And/or grime off your soft top convertible roof. Everything at this stage should be nice and light. Use your soft brush or sponge to gently remove any loose debris from the surface of the roof.


  • Do: pay close attention to the seams and corners where dirt may accumulate.


  • Don’t: over do it with the brush. If the stain/mark is too hard to remove. Just be patient we got more to come. So, it shouldn’t be getting away that easily!

Step 3: Wetting Your Roof

So, simply and thoroughly wet the entire surface of your cabriolet roof with water. Using a hose or bucket. No need for a pressure washer. Here, we’re trying to bring the dirt a little bit more closer to the surface. Another way of describing this step is to flood your cabriolet roof with water.


  • Do: make sure to wet both the fabric. And any plastic or vinyl components.


  • Don’t: use a pressure washer… Except if you’re experienced and know what your doing.

Step 4: Apply Your Cleaning Solution

So now, simply dilute a mild detergent or specialized cabriolet roof cleaner according to the manufacturer’s instructions. Then apply your cleaning solution to the entire surface of the roof using it’s spray mechanism (if available). If not a soft-bristle brush or sponge should do. And you can use your sash brush for the finer areas.

Here, you can be a little more aggressive than you was when flooding your cabriolet roof top with water. So, scrub your soft top. But, in a circular motion.


  • Do: when scrubbing, pay extra attention to any stained or soiled areas.
  • Do: use the sash brush for more sensitive areas. Whilst taking more care.


  • Don’t: be too aggressive. Try to agitate your soft top roof. Not scape it!


So, as an extra benefit. If you are experimenting with a new cleaning solution… You can scrub only half your cabriolet roof first. Then after you’ve finished cleaning only this half of your soft top roof… You can then compare it to the other non-cleaned side. Photographing this difference can assist you to compare your new cleaning solution to a previous one… Or any future ones!

Step 5: Rinsing Your Cabriolet Roof

So, using clean water, thoroughly rinse off the cleaning solution from your cabriolet roof top. Try to ensure that all traces of soap. Or detergent are completely removed. In fact, to ensure all traces of the detergent are completely removed you may have to gently scrub your damp soft top again. So do it. But gently! If you see your roof soaping up again… Even a little bit… Then you’ll have to rinse it with water again.


  • Do: scrub the entire roof (or half – if your doing the experiment) before rising it again. But again be gentle when scrubbing.
  • Do: try to rinse your soft top roof from the middle down to the sides. Allowing any detergent or soap to flow away from the roof.


  • Don’t: use a pressure washer… Except if you’re experienced and know what your doing.

Step 6: Drying Your Cabriolet Roof

Next up is drying… So simply and gently pat the roof dry using a soft microfiber cloth or towel. Keep going until relatively dry.


  • Do: use an absorbent cloth or towel. Having more than one at hand can speed up this process up dramatically.


  • Don’t: pat your soft top convertible roof too aggressively to prevent damaging it. Some people can get heavy-handed at this stage.

Step 7: Finishing Touches

Well, you’re almost done… So, simply inspect the roof for any remaining stains or spots. Also and if necessary, repeat the cleaning process on specific areas until desired results are achieved. Finally for added protection, consider applying a specialized cabriolet roof protective spray or sealant according to the manufacturer’s instructions.

Important Tips:
  • Firstly, always refer to your vehicle’s owner manual for any specific cleaning instructions. Or product recommendations.
  • Secondly, avoid using harsh chemicals. Abrasive brushes. Or high-pressure washers as they can damage the fabric. Or its waterproofing properties.
  • Lastly, try to regularly clean your cabriolet roof to prevent dirt building-up. And maintain its appearance.
