Maintenance : Composite Granite Sink

My black composite granite sink developed a white haze after about 8 months. Mr. Clean's Magic Eraser removed the haze with ease.

What mineral makes granite pink :
Orthoclase feldspar


Vinegar, with a pH of 2.8, is very acidic and as a result will etch any sealed finish on your granite. Typical etchings will appear as hazy areas, dull spots or rings.

How to clean composite granite sink :
According to a website by FRANKE fine sinks and baths, http://www.frankeksd.com/cleaninginstructions.php?node=30&cleanid=3, clean a granite sink by using a soapy nylon brush in circular motions. Rinsing and drying is very important in avoiding film build-up. Never use abrasive cleaning products. Please refer to the site for additional suggestions about cleaning stains.

Granite Composite - The most durable sinks on the market today. Thanks to an extremely high density of rock particles at the sink's surface, these sinks offer supeiour scratch, chip and heat resistance. These sinks will weather hot pans, dropped utinsils, tomato sauce stains and other harsh conditions beautifully. And they offer heat resistance to 535 degrees Fahrenheit, which means a pan can go from stove to sink without burning or marring the surface.
