SOAK Flatter is a starch-free smoothing spray made to relax wrinkles and keep fabric looking fresh for sewing, quilting, and everyday wear; This Pineapple Grove full-size bottle delivers 248 mL (8. 4 fluid ounces) of scented pressing prep that works well on cottons, linens, and blends. Mist lightly, smooth by hand or press with an iron once the fabric settles, and always test first on an inconspicuous area before treating the whole project.
