Using your POSEIDON oval matte white ceramic basin is easy. Just place it on your countertop as it's designed for above - counter mounting. When it comes to the pop - up waste, make sure to install it properly according to the instructions if you've purchased it separately. For daily use, you can use mild soap and a soft cloth to clean the basin. Avoid using abrasive cleaners as they can scratch the matte white finish. Don't place heavy or sharp objects in the basin to prevent cracking or chipping. Regularly check the mounting and the pop - up waste to ensure they're in good condition.
