How to Restore Black Granite Sinks

Originally published during the early development of the Supreme Surface® Care Methodology, this video demonstrates one of our first successful composite sink restoration processes.

At the time, we used the best products available to solve real customer problems. Through years of professional restoration, field testing, and customer feedback, that process evolved into today's Supreme Surface® Composite Sink Restoration System.

If your black composite sink looks rich and dark when wet but becomes hazy, chalky, or faded when it dries, the cause is usually bonded mineral deposits, surface contamination, and years of wear—not permanent damage.

Today, our proven restoration methodology combines three Supreme Surface® Product Solutions:

✔ RESET
Removes bonded soap scum, hard water minerals, and surface contamination without unnecessarily degrading the surface.

✔ HEAL
Restore, Revive & Refresh Composite Sink Treatment. Developed from years of real-world experience to restore color, improve appearance, and recondition resin-rich composite sinks.

✔ GUARD
Clean, Beautify & Protect with ioSeal®. Helps resist hard water buildup, stains, and everyday contamination while making routine cleaning easier.

Although this video demonstrates our original restoration process, the current Composite Sink Restoration System has been refined and improved over many years of professional use.
