Shake bottle well. 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. Remove excess waste with a paper towel, then saturate the problem area. If treating carpet, cover two times the carpet area to be sure you are using enough product to reach the carpet backing and padding. Allow at least five minutes for the product to penetrate the surface, then blot excess with a clean white cloth or paper towel. Allow area to dry naturally. Once the area is completely dry, any residual odor will disappear. If odor persists, repeat as needed.
