Natural stone can be classified into two general categories according to its composition:

  • Siliceous stone
  • Calcareous stone

Siliceous stone is composed mainly of silica or quartz-like particles. It is usually very durable and relatively easy to clean with mild acidic cleaning solutions. Types of this stone are: granite, slate, sand-stone, quartzite, brownstone and blue stone.

Calcareous stone is composed of mostly calcium carbonate. It is extremely sensitive to acidic cleaning products and sometimes requires different cleaning procedures. Refer to your fabricator. Types of this stone are: marble, travertine, limestone and onyx.

Sealing

The purpose of sealing your granite is to keep it from getting cloudy or stained due to extensive use. It is recommended to seal every one to two years, but if the stone gets a lot of use, sealing every six months is better.

How to clean granite counter tops

The easiest way of cleaning is to simply use warm water and mild, phosphate-free, biodegradable liquid dish soap, preferably light-colored and containing no aromatics. This is a gentle way to clean the grease and grime from your granite counters without damaging them. If you use plain soap and water, this can lead to soap build up and over time, will dull the glossy finish of your polished granite.

After cleaning you should rinse the counter tops thoroughly and dry with a cotton cloth

Never use powdered cleansers to clean your stone as they contain pumice which is an abrasive.Never use acidic cleaners that may include ammonia when cleaning granite counter tops.You can also buy special mild granite cleaners specifically designed for cleaning stone.

Avoiding Scratches

Granite is a quartz based material and can be scratched by anything harder than quartz (such as diamonds). Although knives cannot scratch granite, granite will dull your blades quickly - so it is not recommended to cut on granite surfaces. Certain stoneware dishes containing silica sand (such as pizza- stones) pose a risk of scratching.

Cutting Board

If you use a marble cutting board make sure the rubber or plastic feet remain secure - remember anything as strong as granite can scratch granite! We even suggest removing diamond rings before cooking.

Fissure

A fissure is a small surface crack that originates from the heat and pressure process the stone experienced during it's formation. These fissures will not effect the quality of your installation or the durability of the countertop. Occasionally, if the fissure is large enough, it can be filled with epoxy and color- matched. Please be aware that you may or may not notice the fissures during the selection process as the lighting in your kitchen may be different from the showroom.

Formations

You may occasionally notice a piece of Quartz or other stone type that is molded into your granite slab. These rocks may not match perfectly to the flow of the stone, but they certainly make your stone an original. These small rocks found their way into the granite while it was heated, and as it cooled, the formation solidified around it. It is possible, on occasion, to cut around these types of formations, but no fabricator can guarantee a perfect stone.
