Natural Stone and Quartz Countertops:
Clean stone surfaces with a neutral cleaner, stone soap, or a mild liquid dishwashing detergent and warm water.
Similar to any item cleaned in your home, an excessive concentration of cleaner or soap may leave a film and cause streaks. Follow manufacturer recommendations.
Use a clean soft cloth on surfaces for best results.
Rinse the surface thoroughly after washing with the soap solution and dry with a soft cloth.
Change the rinse water frequently.
In the bath or other wet areas, soap scum can be minimized by using a squeegee after each use. To remove soap scum, use a non-acidic soap scum remover or a solution of ammonia and water (about
1/2 cup ammonia to a gallon of water). Frequent or over-use of an ammonia solution may eventually dull the surface of some stone types.
Many suppliers offer products used for stone cleaning.
Products containing lemon, vinegar or other acids may dull or etch calcareous stones. Do not use scouring powders, creams, and/or sponges as they often contain abrasives that may damage countertops.
Many commercially available rust removers (laundry rust stain removers, toilet bowl cleaners) contain trace levels of hydrofluoric acid (HF). This acid attacks silicates in addition to other minerals. All stones, including granite and quartzite, will be attacked if exposed to HF.
Do not mix ammonia and bleach. This combination creates a toxic and lethal gas. Natural Stone and Quartz Countertops:
Honed or Leather Finish
For daily cleaning of honed or leather finished stone or quartz products, use Countertop Magic® or mild dish soap with warm water and a soft clean cloth.
All of the cleaners mentioned above can be purchased at most hardware stores.
Quartz (excluding some honed or leathered products) surfaces do not require sealing.
Natural Stone (excluding Soapstone)
Your countertops have been sealed prior to installation. Some stones will only need sealing every few years depending on the stone’s porosity and your daily use of the countertops. To determine if your countertop needs resealing, perform a “water test”. Learn how in the “Additional Information” section.
Few granite and most marble, limestone, and travertine require an immediate application or multiple applications of sealer by the homeowner. The natural porosity of these stones and its use in your home requires them to have more initial sealing.
To seal your countertops, stone sealers are available through various stone suppliers and hardware stores.
General Sealing Instructions (always follow the directions provided with your product.)
Sealer penetrates the stone, buying you time to wipe spills up. Sealer is not a lacquer type coating; therefore spills should be wiped up in a timely manner. Spills left over a period of time could seep into the stone and cause staining.
If you are uncertain if your stone needs to be resealed, perform a simple “water test”. Place some water onto your stone. If within 15-20 minutes the water begins to absorb into the stone, it is time to reseal. Wait for the water spot to evaporate before resealing.
It is extremely difficult to chip your countertop. In the event you get chip save the pieces, it can be repaired by a stone technician.
Even though it is extremely difficult to scratch granite and quartz surfaces, the use of a cutting board is recommended.
Granite does NOT harbor bacteria or mold. Tests conducted by the Hospitality Institute using e-coli contaminates show granite is second only to stainless steel in bacteria resistance.
Stains can be removed. Depending on the nature of the stain the most common method is a poultice of peroxide and cornstarch. This paste applied to the area and allowed to dry will pull the stain from the stone. Occasionally more than one application is required. For more information on stain removal please see https://www.naturalstoneinstitute.org/consumers/care/
Natural pits or fissures in the stone do not have anything to do with how porous it may or may not be. Do Not use plumber’s putty or any oil based adhesives on your tops.
Do Not use Scotch-Brite®, scouring or steel wool pads, or any acid based cleaner on your countertops.
Do Not use a Crock Pot, Insta Pot, Rice Cooker, or similar directly on your quartz countertops.
Quartz is more susceptible to scorching or cracking from high heat items. For added protection use a trivet or cutting board.
Etching. (Slate and most granites are acid resistant.) When acid comes into contact with a stone surface, a chemical reaction takes place that may cause etching. Sealing will give you time to wipe up spills but can not stop the chemical reaction. Many household foods and cosmetics contain acids that can degrade a stone’s surface. Some acidic foods are: juice, coffee, wine, soft drinks, tomato based products, and lemons. Do not leave these items resting on your countertops for any length of time.

This warranty is issued only to the original purchaser (the party whose signature appears on this warranty, or if no signature appears, the party by whom Rock Tops was paid), and is not transferable. However, this warranty also governs any claims which may be filed by the original end-user. The following guidelines are intended solely to clarify an understanding of certain properties, characteristics, or conditions associated with Rock Tops products and installation services. They do not represent all of the properties, characteristics, or conditions which may be covered or which may be excluded from coverage under this warranty. Color and veining: Stone countertops are composed of natural materials and are subject to variations in background color, veining distribution and veining pattern. The color, shade, veining, color concentrations (blotches), and any other variances in the appearance of natural stone will exist and will vary between a sample you may have used in the selection process and the actual stone(s) used on your project, between two stones, and even within the same stone. Such naturally occurring variations are to be expected in stone and are not considered defects. Finish: Your countertop will come with a polished finish (unless ordered in another finish). Irregularities in the finish and gloss levels of natural materials like stone are common, reflecting the unique natural patterns and finish that give each stone countertop its distinctive appearance. Finish and gloss will vary from piece to piece and on the same piece. Surface irregularities and thickness: Natural stone is composed of minerals and is earth-formed over hundreds of millions of years. Fissures, pitting, mineral pooling, and other naturally occurring features in stone should not be considered as defects, and are not covered under this warranty. The thickness of stone slabs vary, therefore thickness designations (i.e. 3 centimeter) are nominal rather than exact. When pieces of different thicknesses are joined, it is common practice to grind the underside of one piece to blend evenly with the other piece. Seaming: Placement of seams (including the use of “rails”) is solely at the discretion of Rock Tops, will be discussed at the time of template and finalized during engineering. Seams will be visible to the eye and touch. Every effort will be made to insure the seam is placed in the best location for the structural integrity of the countertop and to make it aesthetically pleasing. Due to the unique characteristics of stone, it is not possible to guarantee a match in color, veining (including the direction of veins) or finish when seaming two pieces together. Additionally, stone slabs may contain some bowing or warping, therefore in some instance’s seams may not be level across their entire length. Staining: All countertops are sealed prior to installation. Annual sealing is recommended to enhance stain resistance, and such sealers may be purchased easily. When properly sealed and maintained, stone countertops are generally quite stain-resistant to common beverages and foods. In those instances when a stain occurs, it is generally not possible to remove it, and such stain is not covered under this warranty. It is very possible for certain chemicals and cleansers to stain stone. If such liquids are spilled on stone, they should be wiped off immediately with soap and water. Most home centers sell a line of products designed specifically for the care of stone countertops. Additionally, you may use warm soap water or mild household cleaning agents to clean your countertop. Avoid strong chemicals and solvents. Do not use nail polish remover, permanent markers, inks, oil soaps, furniture cleaners or paint strippers on the countertop. Also, avoid using high alkaline/PH level cleaners, such as oven cleaners on the countertop. Scratching: Many types of stone countertops (i.e. granite) are extremely hard surfaces and very resistant to scratching. In the rare instance when a scratch is discovered, it is generally not possible to repair or remove it. The top should not be used as a cutting surface since it will dull your knives. The use of cutting boards is recommended. Temperature: Stone countertops are very heat resistant and unlikely to scorch. Thermal shock or cracks may occur if the countertop is subject to extreme temperature changes. It is recommended that you protect your countertop from extreme heat by using trivets or hot pads, as damage resulting from heat is not covered under this warranty. The following is an excerpt from Section 14 of “A Homeowner’s Guide to Natural Stone Countertop Installation” published by The Marble Institute of America is an integral part of this warranty: Fissures occur naturally in many stone types. A fissure is defined by the American Geological Institute as “an extensive crack, break, or fracture in the rock, which may contain mineral-bearing material.” The term “fissure” is used commercially in the stone industry to describe a visible separation along intercrystalline boundaries or the voids between mineral crystals. This separation may start and stop within the field of the stone or extend through an edge. A fissure differs from a crack in that it is a naturally occurring feature in the stone. Cracks occur in stones as a result of mechanically induced stresses during handling, fabrication, transport, or installation. When cracks are detected in slab material prior to fabrication, the best method is to simply avoid them during the layout process. In stones with lesser soundness properties, this option may not be possible. When working with such stones it is common practice to repair cracks by cementing them together with epoxy or polyester resin. (Repaired cracks are not indicative of defective product or workmanship, and are specifically not covered under this warranty). Chips can occur in stones either as a result of sawing operations or handling. Chips may be repaired with epoxy or polyester resin if the completed repair is consistent in color and texture with unrepaired areas of the slab. Pitting of the countertop surface, particularly in granite, is a common characteristic of natural stones. Granites are made up of several different minerals, each mineral having a different hardness. Granites contain quartz, feldspars, biotite, amphibole, ferrous titanium oxides, and other minerals. On the Mohs Scale, diamonds are the hardest mineral, with a rating of 10. Quartz and feldspar have a hardness of 6.5 to 7 and are very durable. Biotite (mica) is very soft (2.5) and flakes easily. All true granites have biotite in their composition. Because biotite is soft and flaky, the first few layers are removed during the polishing process, causing pits throughout the slab. Some granites have more biotite throughout their composition than others. The higher the biotite content of the stone, the more pits it will have. Most polished igneous rocks will have varying degrees of pits, depending on the amount of biotite, muscovite, and phlogopite in their composition. The pits do not make the granite less durable or otherwise inferior. Pits are common in all granites and should be expected. I have carefully read and thoroughly understand all of the information contained in this warranty.
