Using your POSEIDON white ceramic basin is easy. Just install it on your countertop as directed. When using, avoid dropping heavy objects into the basin to prevent cracking. For daily cleaning, use a mild soap and a soft cloth. Don't use abrasive cleaners as they may scratch the matte white surface. If you notice any clogs in the 32mm waste, try using a simple drain cleaner. Remember, the plug and waste are sold separately, so make sure to install them correctly.
