An apparatus and a method for dispensing a wash solution, conveyed into a washing device, at a desired concentration of detergent chemical. The apparatus includes a first tank for a wash solution at a desired concentration. Supply water passed through measuring elements is divided into partial flows along at least two lines. At least one line conveys detergent chemical along with water into the tank, and at least one second line supplies plain water. The apparatus includes at least one second tank, into which at least a detergent chemical-containing partial flow is conveyed into the first tank. The second tank has a first surface level sensing element which indicates the attainment of a design volume and the amount of water which has flown through the measuring elements at the indication moment and which provides a basis for determining the concentration of detergent chemical in the second tank.
