Herein disclosed is a foaming nozzle to be mounted in the front of a spray nozzle of a sprayer so that a liquid detergent may be sprayed in a foamed state onto a window glass or the like to clean it. The foaming nozzle has its mouth so shaped that the mixed cluster of the mist and foam from the foaming nozzle may be sprayed in a band, elliptical, rectangular or triangular shape and at a wide angle. At the same time, the positional relation between a spray port and the foaming nozzle is so determined that the mist spin-sprayed at a high swirling speed may be partially mixed with the foam, which is formed by the impingement of the mist upon the inner face of the mouth of the foaming nozzle, and that the mixture may be sprayed at a wide angle. The foaming nozzle is composed of first and second foaming nozzles, of which the first one is mounted in the spray nozzle, as described above, whereas the second one is formed into the shape of a circular cylinder and removably hinged to the first one so that the mist-foam mixed cluster may be sprayed in the sectional shape of a band from the first foaming nozzle with the second foaming nozzle being removed and so that foam may be sprayed in the sectional shape of a circle with the second foaming nozzle being unremoved. In short, the user can selectively spray either the mist-foam mixed cluster having the band section or the foam cluster having the circular section freely, if necessary.
