1. A device for removing stains from fabric using cleaning solution, comprising:
- a hollow base member having upper and lower surfaces, said base member including an opening in the upper surface thereof;
a screen superimposed over the opening in the upper surface of the base member;
a support member integrally mounted to the base member, said support member extending upwardly from the upper surface of said base member and having a first opening therein for receiving cleaning solution and a second opening therein for delivering cleaning solution to the stained fabric;
a piston/nozzle assembly disposed within said support member, comprising;
a cylinder disposed within the support member, said cylinder capable of projecting from and retracting into the second opening of the support member and including a closed end and an open end;
a piston disposed within the cylinder capable of projecting from and retracting into the open end of the cylinder;
multiple nozzles for delivering cleaning solution to the stained fabric; and
attachment means connecting the nozzles to the piston;
a lever fixably mounted to the support member; and
means for transporting cleaning solution from the base member to the piston/nozzle assembly.

Abstract
A device for removing stains from fabric is a household laundry appliance that mechanically removes stains or spots from fabric. A piston/nozzle assembly lowers from a piston housing in the device until it contacts the non-stain side of the fabric. Multiple nozzles force cleaning solution through the stained fabric at a high pressure, thereby exculpating the particles causing the stain. The cleaning solution flows through the fabric, through a screen below and into a reservoir in the hollow base of the device. The cleaning solution may be recycled for later use.
