Water and detergents contain mineral salts that form insoluble deposits on the fabric, which can act as a fuel if exposed to flames.

UAO is a fabric-based rinse agent with a pH 5.5 formulation that is perfect for contact with the skin. Thanks to its excellent cleaning capacity, UAO separates any inorganic trace and detergent from the fabric that can decrease its fire resistance. When UAO is used, no deposits are created on the fabric and inside the washing machine.
UAO must be dosed inside the washing machine in the special compartment dedicated to fabric softeners.
The amount of UAO softener to be used is specified on the fire certification of reference.
