Using the Elkay 3 - Hole Deck Plate/Escutcheon is easy. Just place it over the three faucet holes in your sink. Make sure it's centered for a nice look. When cleaning, use a mild soap and a soft cloth. Avoid using abrasive cleaners as they can scratch the surface. To keep it looking great, dry it thoroughly after each use. This will prevent water spots and rust. If you notice any dirt or grime in the corners, you can use a small brush to gently clean those areas. Also, check regularly to ensure it's still firmly in place over the faucet holes.
