Before use, apply a small amount to an inconspicuous area to test for colorfastness, allow test area to dry completely and observe any color changes. Do not use on wool, silk or leather. Soak up excess liquid or residue. Saturate problem area with product. If treating carpet, cover two times the carpet area to be sure you are using enough product to reach the carpet backing and padding. Let sit for 3–5 minutes, then blot gently with a clean, damp colorfast sponge or cloth. Repeat if necessary. Not intended for use in carpet cleaning machines.
