SOLUTION
Fill the solution tank with clean water at a temperature no greater than 50°C and add
liquid detergent in the proper concentration, following the instructions of the
manufacturer. The formation of excess foam could damage the suction motor, so use
only the minimum amount of detergent necessary.
Always use low foam detergent. To avoid the production of foam,
before starting to clean, put a minimum quantity of antifoam liquid
into the recovery tank.
Never use pure acid.
