The EvoEnzymes line by Fra-Ber complies with the provisions stipulated by VDA (Verband Der Automobilindustrie). A German automotive industry association incorporating members that are also leading German car manufacturers, including Audi, Mercedes, Porsche and their suppliers.
Class A obtained by Fra-Ber products is synonymous with more protection of delicate parts of the vehicle, such as galvanised parts and aluminium.

The Evoenzymes line has been tested to reduce the risk of damage caused by corrosion for various car body and components, through external laboratory tests on specific surfaces, such as, for example, on decorative surfaces made of aluminium or galvanised bolts. A surface was considered resistant when no damage or corrosion were visible on plain sight. All Evoenzymes placed on the market have undergone these tests.

Moreover, many products of the Evoenzymes line for use on the vehicle exterior bear the green seal “VDA di Klasse A”; this guideline was drawn up in order to more effectively prevent damage to vehicles subjected to washing, offering a proper balance between car-wash, vehicle and chemical detergents. The products are evaluated in terms of their aggressiveness and corrosive effect on sensitive types of surface protection at high temperatures.

The VDA publication applies to:

• Manual self-service and power washers.
• Gate-type car-washes.
• Conveyor-type car-washes.
• Wash components.

The purchased product has undergone tests to reduce the risk of damage due to corrosion to the components and the body of the vehicle. The products are evaluated in terms of their aggressiveness and corrosive effect on sensitive types of surface protection at high temperatures. The detergent is approved by a VDA seal when the treated surface, according to the guidelines, is resistant to corrosion damage and optical deterioration.

It is important for the client who buys a product with a VDA seal to know that since it falls under a “self-service” application, it is impossible to pre-determine the setting time of the products such as the “insect
remover” or the “Rim Cleaner” that are sprayed prior to washing. Therefore, it is essential to make sure to have a Class A VDA seal like Evoenzymes products.
