Care & Maintenance
Daily Cleaning Wipe the sink down after each use with a soft sponge and warm soapy water to prevent residue buildup.
Stain Removal Use a mixture of baking soda and water for stubborn spots, rubbing gently in the direction of the stone grain.
Hard Water Care Periodically rinse with a 50-50 mix of vinegar and water to eliminate mineral deposits from the black onyx surface.
