The products for the exterior (polish, wax etc…) should only be used on clean and dry vehicles.
Avoid using the products with paper towels (risk of damage to finish).
For interior cleaning products in the Fabric Cleaner/Stain Remover group on delicate surfaces, such as alcantara, try a little on a non-visible area. In the case of seat stain removal, it is recommended to clean the whole seat in one go in order to avoid ringed stains.
