The apparatus includes an elongated wash tank and an elongated rinse tank each having a plurality of conduits disposed adjacent to the bottom thereof. Conduits in the washing tank are connected to a Wye. One inlet branch of the Wye is supplied with air at a pressure of at least 15 psi and the second inlet branch of the Wye is connected to a recirculating pump having an output of at least 30 psi. A mixture of pressurized air and water is discharged from apertures in the elongated conduits and forms vortices in a bath of water held in the tank. Window blinds are suspended in the tank in contact with the vortices. The elongated conduits in the rinse tank are supplied with air at a pressure of greater than 15 psi. Air is discharged from the elongated conduits in the rinse tank through vertically directed openings. After the blinds are washed in the wash tank they are inserted in the rinse tank and thereafter removed and air dried.

Window blinds are cleaned by suspending a blind in a tank containing a bath of water. Pressurized air and water are discharged from openings in elongated conduits into the bath so as to form vortices contacting the blind. After the blind is washed, it is rinsed and dried.
