Diversey, a world leading company who manufactures cleaning products, performed a compatibility study of the effect of its cleaning products in earthenware and porcelain products.

Costa Verde was selected for this test as it is one of the biggest earthenware and porcelain manufacturing companies for the European Horeca market.

The following products were used in this study:

• 1 Suma Revoflow Max P1 (powder detergent with a high level of alkalinity and containing chlorine).
• 2 Suma Revoflow Max P2 (detergent similar to P1 but without chlorine).
• 3 Suma Nova L6 (liquid detergent).

Diversey concluded that the plates manufactured by Costa Verde did not present any evidence of damage following approximately 450 mechanical washes using the selected products (with or without hypochlorite).

We, thus, once again had confirmation of our products' resistance level to industrial washing as well as to chemical agents. Also, this confirmation is not issued by us, but rather by an independent entity, Johnson Diversey, a world leading company in the professional hygiene and cleaning sector.
