After blending your stain with the TAWABIKA stain remover stick, sprinkle the stain generously with Terre de Sommières and leave for several hours, or even overnight for the toughest stains. Then brush gently to remove the terre de Sommières. If necessary, repeat the process until the stain is completely gone. Terre de Sommières is an effective natural stain remover for greasy stains such as oil, butter and grease. This product is made in France.
