A stain removal accessory that cooperates with a stain removal device for treating a stained area is attached to a front head of the stain removal device, namely to a water and/or steam venting face of the stain removal device. The stain removal accessory includes a container like a pad, a cartridge, a sachet, or a capsule provided with a permeable external layer, for containing a stain removing material, and a flap-flip piece including a holder for holding the container, whereby the stain removal accessory is adapted to release the stain removing material on the stained area when cooperating with the stain removal device by facing a flow of water and/or steam generated by the stain removal device.
