White Haze On Granite Composite Sinks
One of the more common issues related to a granite composite sink is preventing and removing the white haze. When a composite granite sink is new, the colors are vibrant and the surface has a nice sheen. With proper care and some do's and don'ts, these sinks are simple to keep looking like new for years to come. Even on the darker colors, brown and black.
White Haze More Noticeable On Black Composite Sinks
The white haze is usually more noticeable on darker colors such as black and brown vs the lighter colors, white and cream. There are two things that typically cause the white haze; etching and mineral deposit buildup. If your sink has become etched, the damage is irreversible, but in many cases can usually be masked.
Mineral Deposit Buildup, Calcium & Limescale, Causing the White Haze
Unless you wipe your sink out after every use, water will evaporate leaving behind minerals. These minerals (calcium and lime) bond to the surface, progressively building up and causing the white haze to occur.
Removing Mineral Build-up Causing The White Haze
According to the Marble Institute of America, all natural stones should be cleaned with pH neutral cleaners. As a note, pH neutral or balanced cleaners are not formulated to remove mineral deposits. Most leading brands that are formulated to remove the white haze/mineral buildup, are considered harsh and can etch the surface, causing permanent damage.
White Haze Caused by Etching
When a granite sink has been etched, particularly on black composite sinks, it resembles the look of burnt charcoal or a white haze. Much like polishing a piece of black granite, the color transitions from a charcoal color to a dark black reflective surface. But when etched, it does this in the reverse order. If this is the case, although it can be masked to look better, it is typically irreversible without the help of a professional stone care product.
Prevent The Haze and Restore The Look
As we mentioned above, try to wipe the water out of the sink after every use. This will reduce the exposure to mineral deposit build up.
Prevent The Haze With ioSeal
Supreme Surface® Granite Quartz & Marble Treatment is formulated with ioSeal. This unique product bonds a protective barrier to the surface, helping prevent mineral deposit buildup, calcium and limescale. Colors tend to become more vibrant every time you clean. Add a level of preventative maintenance to new sinks or improve the look and feel of damaged sinks.
