Using this POSEIDON basin is easy. Just install it above the counter as it's designed. For everyday use, simply use regular water and a mild soap to clean the basin. Avoid using abrasive cleaners as they may scratch the matte white ceramic surface. When it comes to the pop - up waste, since it's sold separately, make sure to install it correctly according to the instructions that come with it. Check it regularly to ensure it's draining properly. Also, don't put large or hard objects down the drain to prevent blockages.
