An etch is a dulling mark on stone that appears as a stain. An etch is a chemical reaction between the calcium in the stone and any liquid that has an acidic PH

Liquids such as beverages, food items and cosmetic items with an acidic PH can etch the finish of your stone.

The acidic nature of any item will react to the calcium in your stone leaving a dull mark that cannot be removed with cleaning.

Scratches can occur on softer stones such as marble, limestone, travertine, onyx and soapstone.

Scratches ruin the finish of your stone and cannot be removed with cleaning.

Our Slate Cleaning & Polishing Process

Our natural stone cleaning systems are performed to IICRC standards for S210 stone restoration. We use the most cutting-edge technology to deliver the ABSOLUTE BEST CLEAN. Our standard natural stone cleaning process removes any topical soil. Any staining or damage not removed by our standard natural stone cleaning process will require either a “partial restoration” or a “full restoration”.

  5. Emulsify: a chemical rinse that is the 2nd rinse step synergistically reacts with the pre-treatment to attract all chemical and soil to the surface

  6. Neutralize: a chemical rinse that is the 3rd step in the rinse step that flushes all residue and solutions out, neutralizes them, and brings the tile & grout PH back to balance PH7 to prevent re-soiling.

FAQ'S

  • Hot water extraction cleaning method is recommended over other methods

  • Residential cleaning frequency is once every 12 months or once every 6 - 12 months for high moisture areas.

Drying time after service vary based on room temperature, relative humidity, and air movement. Generally grout remains damp after service for 4-8 hours.

Floors are walkable immediately after service.

Counter tops and vanities are usable immediately after service.

Natural stone covers a broad spectrum of materials such as marble, granite, slate, terrazzo, onyx, blue stone, sand stone, travertine, limestone, flagstone, among the more popular. Each type branches out to several different families. For example, Marble has over 15 common types that are quarried from all over the world, and all range in hardness, patterns, application, finishes. To further explain, you may have a mosaic – emperador brown – polished finish – 3/8″ used on a floor application. To make a long story short, every floor is different, and likewise would have different need of service.

Natural stone covers a wide array of materials such as marble, granite, limestone, travertine, terrazzo, onyx, sandstone, flagstone, bluestone and slate. These materials come in many different styles of finish such as polished, honed, tumbled, flamed, antiqued, textured, and natural. In today’s market, the use of natural stone has grown in demand, and the dynamics of which they are used range anywhere from floors, to countertops, to wall coverings both interior, and exterior.

All natural stones are pores by nature, which means they need to be sealed regularly to prevent staining. Natural stones that are placed in a high moisture area such as showers, and countertops need to be sealed more often. The schedule for re-sealing natural stone depends on several factors such as amount of use, hardness of water in the area/city, and the types of chemicals used or come in direct contact with natural stone surfaces.

Along with being pores, natural stones are PH sensitive. High PH cleaners may dull your finish, and remove existing sealers. Acidic PH chemicals may etch and damage a finish, and cause pitting. Contrary to popular belief, vinegar water is NOT a good way to clean natural stone. Vinegar, along with most food items and beverages are acidic in PH and may ruin the finish of your stone.

I had a very good experience with CSI. They helped me to save black marble that was ruined by acidic cleaner. Stone looks like new! They are easy to reach over email, they provide a free estimate, they also show up on time! Most important they do a great job! Very professional! I'm glad I went with this company!!!

Andre was outstanding. The actual price he charged was significantly lower than the estimate due to the condition of my marble bath (talk about honest).  He was right on time, super efficient, thorough and careful (put up lots of plastic and covers on his shoes).   The results exceeded my expectations, so I asked him of he could squeeze in the kitchen before he left.  For a nominal fee he polished up my kitchen counter & island.  On Monday morning I received an updated invoice with detailed listings of the price changes.   Nice job !!
Thanks
