Stone drying mat for use around a faucet and sink, made of diatomaceous earth. Care instructions: 1. When you first use the mat, you may notice a small amount of powder on the surface. This is completely normal and is due to the presence of diatomaceous earth in our product. You can easily remove it by wiping the surface with a damp cloth. 2. If your mat's surface is dirty, you can clean it by wiping it down with a damp cloth. For tougher stains, use the included sandpaper to gently sand the area before wiping it clean.
