In principle, the convertible soft top needs, in our opinion and having regard to any special care.
For cleaning, we recommend hot water and a soft brush.
The water can really be very hot, even boiling water would be – at least for the soft top – harmless. The top fabric is laminated to one another with much higher temperatures and the glues used are all well over 100 degrees heat resistant.
If you use detergent – of any kind – please make sure to rinse the lye residues with plenty of clear water.
If you consider this, you can use special cleaners for cleaning of course.
