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 to occur and one of them causes permanent damage.

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 cause permanent damage.

The Supreme Surface Scum and Mineral Deposit Remover is a safe and effective way to remove the minerals causing the white haze without damaging the sink.

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 made to look better,  it is typically irreversible without the help of a professional stone care product.

Helping Prevent The White Haze

As we mentioned above, try to always wipe the water out of the sink after every use. This will reduce the exposure to mineral deposit build up.
The Supreme Surface All-In-One Granite, Quartz & Marble Treatment with ioSeal will clean, polish and progressively seal with every use. Although “NOT” formulated to “remove” mineral deposits, it will help protect against this type of damage.
