Question: "I am interested in your cabriolet roof cleaning service, but do you also clean mould from the inside of the roof?"
Answer: Cars with convertible roofs are more prone to leaks than other cars. When the hood is closed, there are all sorts of rubber seals that need to be clean and snug fitting. There's also additional drainage systems which can get blocked up. It sounds to me like your car has a leak which is letting in water, which causes a nice damp environment for mould to grow. Mould is something which should be taken seriously, so we'd recommend fixing any leaks and drying the car, otherwise the mould will just grow back.
