Visible stain detection powders

These powders should only be used indoors. A visible stain powder should be selected based on its natural color blending with the color of the target object. It should be carefully dusted on the object with a soft applicator brush. When contact with the object is made , a transfer occurs. When the transferred powder contacts moisture, such as perspiration, facial fluids or water, the powder goes into solution and a resulting vivid color appears.
