White Haze On Granite Composite Sinks

White Haze On Granite Composite Sinks

When a composite granite sink is new, the colors are vibrant and the surface is easy to clean. With proper care and some do's and don'ts, granite sinks are simple to keep looking like new. Even with the darker colors, such as brown and black.  

Causes of The White Haze on Composite Sinks

There are two very common issues that resemble the look of a white or chalky haze on black granite composite sinks. One is caused by mineral deposits (calcium and lime) and the other is a damaged surface. A sink with a damaged surface is particularly noticeable on black sinks and caused by either chemical etching or some sort of an abrasive pad. 

Although removing mineral deposits is an easy fix, we recommend you learn a couple simple steps to avoid advancing to a bigger issue, etching. 

The first step is to identify which issue exists. It all starts with a thorough cleaning with a specific type of product. You'll need to remove all soap scum, grease, oil, and mineral deposits such as calcium, lime and rust. We embedded a 2:00 minute video located below to help you accomplish this task. 

Mineral Deposit Buildup, Calcium & Limescale, Causing the White Haze

Many homes have hard water and this is typically where the issue starts, even if you have a water softener connected. Unless you wipe your sink out after every use, water will evaporate leaving behind minerals. These minerals (calcium and lime) bond to the surface. Early on they can be seen as water spots located in the corners and progressively build up and transition into a white or chalky haze. Although it is highly recommended to use preventative care and maintenance, it is even more important to know how to safely remove calcium and lime without causing serious damage. 

pH Neutral Cleaners Don't Remove Mineral Deposits

Many popular brands of dish soap and all brands of natural stone and granite cleaners are pH neutral. Cleaning products that have a neutral pH are not capable of removing mineral deposits such as calcium and lime.

Harsh Cleaners and Abrasives Cause Etching and Damage Granite Sinks

Before attempting to remove mineral deposits, it is important to know that nearly every product formulated to remove calcium, lime and rust, are too harsh or abrasive for granite sinks and causes etching. This is why it is important to practice preventative care and maintenance. Specialty products and specific technics can avoid an expensive replacement. 

Safely Remove Calcium and Lime From Granite and Prevent Future Issues

With just a few simple steps you can improve the look and performance of your sink. Consider practicing a little prevention by using cleaning solutions formulated with  ioSeal protectants.

Prevent The Haze and Restore The Look

As as already mentioned, try to wipe the water out of the sink after every use. This will reduce exposure to mineral deposit  and soap scum buildup.

Treatments or cleaning solutions that contain ioSeal™ bond a protective barrier to the surface. This barrier helps prevent mineral deposit buildup, while improving ease of cleaning and making colors more vibrant. An additional level of protection every time you clean!

      I called Tom about the damage I had done to my sink by using a vinegar and baking soda solution while soaking some greasy filters. I thought the damage may have been irreversible, but Tom and courage me to try the composite granite sink restoration kit. I got it within 2 days and tried it right away following all his instructions and my sink is like new. I can’t believe how well it worked and I’m so thankful!
