This 12oz bottle of stain treatment will help repel even the toughest stains. See what happens when soy sauce is poured on a piece of stain treated fabric in this blog post. For sofas 1-4 bottles is recomended. For upholstered chairs 1-2 bottles is recomended. Use 2-4 bottles on rugs.
We recommended spraying the textiles you want to stain treat every night before you go to bed until wet. Do this until all of the stain treating solution is gone. Usually 1-2 weeks.
