Understanding Granite Sink Material

The first step to cleaning your hard surface granite sink is knowing what it’s made of. Granite is a natural stone composed mainly of quartz and feldspar. Quartz is a hard mineral made from sea sand. Feldspar is a crystalline material that is full of aluminum oxide.

When quarried, granite is revealed from earth material such as sandstone. Pieces of granite are collected, and the layers of rock are arranged in a horizontal plane. After the granite is removed from the quarry, it travels through a stream of hot water. This softens the surface of the granite. After the granite is steamed, it is cooled under water. The stone is carved into the desired shape and size. It is after that that acid is applied to the surface of the stone. The acid is what gives the granite its unique color.

Problems with granite include staining and etching, especially from acidic foods like wine and juices. Acidic liquids can affect the protective wax coating on your granite sink, causing it to wear away. If the protective coating wears off, the acidic liquid can stain the granite. The acid can also lead to etching, which is a process that causes tiny holes to develop in the surface of the granite. Etching can be prevented by keeping acidic foods away from the sink.

Possible Granite Sink Problems

It is important to keep the sink clean and periodically polished. If you do not follow proper cleaning procedures, you may end up with stains and spots on your sink.

There are several possible sink problems that can be avoided if you follow these procedures.

The first and simplest problem arises from splashing water. Water splashes may leave deposits or rings on your sink. This can be prevented if you wipe the water off after every use.

Another problem that may arise is from excessive water retention. This may happen if you put a glass on the sink or bowl and the water drips onto the granite, which it will if it is not level.

The accumulation of hard water may also result in stains and rings. This can be avoided if the water softener in the house is regularly checked and maintained.

If your sink has been damaged, you can use the following procedure to repair the sink. First lightly sand off the top layer of the granite. Then rub in a thin layer of epoxy over the damaged area. All that you have to do now is restore the shine to the epoxy.

How to Clean Granite and Composite Granite Sinks

Cleaning a granite or composite granite sink may seem like a daunting task but the process is actually quite simple. Keeping your sink clean and looking its best will extend the life and keep it looking beautiful.

Wash and Scrub the Sink with a Scouring Pad. A granite sink is a lot like a cast iron pan when it comes to cleaning. You must use hot, soapy water and a scouring pad. The same goes for composite sinks. Scouring pads are abrasive, so beware of this if you have a delicate surface.

Use a Scouring Powder for Granite Sinks. Another method of cleaning sinks is to use a powder cleaning agent. The powder cleaning agent will provide a less abrasive scrub and is made with natural sea minerals.

Clean the Sink with Baking Soda and Vinegar. This is great for surfaces that are stained or for a sink that has a boring finish. Baking soda and vinegar create a cleaning agent that lifts stain from the surface. The concoction also acts as a polish and has a disinfecting property that will kill bacteria living in the sink. Make a paste out of the two ingredients and scrub. Rinse.

Hope you enjoyed our "How-to" guide and found it useful. Before we wrap up, we wanted to share some general advice regarding Granite and other hard materials that hold up well to water, heat and pressure.

The chemicals used in cleaning products and detergents, sealers and abrasives used in home maintenance products, and bathroom and kitchen cleaners, have a devastating effect on Granite surfaces.

The natural pH balance in acidic liquids and cleaning liquids change chemically when mixed with Granite, and without understanding and knowing the potential outcome of this type of chemical reaction when applied to a Granite surface, homeowners are left with a damaged countertop.

To illustrate and demonstrate the disastrous consequences of applying an acid to any Granite surface, we will show you a YouTube video created by a company that distributes granite sealants and products used to maintain Granite surfaces.

This company focuses on a particular product called Granite Gold Maintain pak, and demonstrates the effects a standard household cleaner, in a well-intended but misguided attempt to clean a Granite surface, has on a Granite countertop.
