Using your Duravit Starck 3 Undermount Sink is easy. Just place your faucets according to your needs, and you're ready to use it for your daily washing. When it comes to cleaning, use a mild soap and a soft cloth to wipe the sink regularly. Avoid using abrasive cleaners or hard - bristled brushes as they may scratch the surface. For maintenance, check the overflow regularly to make sure it's not clogged. If there are any stains, you can use a non - abrasive stain remover. Keep in mind that this sink is designed to be undermounted, so make sure the countertop is properly installed and supported to prevent any damage.
