Our products for your convertible roof: cleaning and impregnation

Your convertible top will start to look less nice over time. Even if you park under a roof as much as possible, the convertible's roof will become stained due to bird droppings, resin, green deposits and rain streaks. The result? Your roof will look less nice and you will face an increased chance of leaks.

It is therefore important to maintain your roof properly. This prevents dirt from causing wear to the material. Clean and impregnate the roof regularly. To enjoy a beautiful convertible top for longer, make it waterproof and dirt repellent.

You can avoid many common problems by maintaining and preventively treating your convertible roof. Leaks at the seams, rain streaks, weather stains and green deposits will be a thing of the past. Your roof will retain its original colour and the rain will roll off it.
