To protect stone floors, walls and counters, we recommend using a penetrating sealer such as MP90/MP90 Eco Plus. Care must be taken to avoid cleaning natural stone with harsh or abrasive cleaners, especially those that contain phosphoric ACID or glycolic acids. Be aware that acidic materials such as vinegar, and lemon juice can etch some stone surfaces such as some of the softer limestones. For maintenance, we recommend FilaCleaner for our tumbled stones and MOSAICS and brushed and honed products. Occasional deep cleaning may be required to restore and maintain the stone’s natural PATINA. Please consult with our sales staff for recommendations.
Creamic & Porcelain Tile
Most of our glazed tiles are fairly maintenance free and require only a regular cleaning schedule. Most cleaning can be done with just an ACID free detergent, soft cloth and clean water. Frequent changing of the water will prevent dirty mop water build up in textured areas of the glaze and the GROUT lines. We recommend FilaCleaner for routine maintenance, PS87 for heavy duty cleaning, Deterdek for inorganic stains (grout haze, rust, limescale) Fuganet for grout joints.
Glazed Ceramic Tile
Most of our glazed wall tiles do not require sealing. Crackled or crazed glazes should be treated with a penetrating sealer prior to GROUTING to prevent STAINING. We recommend MP90/MP90 Eco Plus. Periodic resealing is a necessary maintenance procedure for crazed glazes in wet areas such as showers.
Glazed CERAMIC TILE generally requires little care beyond regular cleaning with gentle soap that contains no acids and a soft cloth. We recommend avoiding the use of cleaners that contain phosphoric acids or glycolic acids that may cause etching and damage to glazes. FilaCleaner PH Neutral is the recommended choice.
Glossy glass tiles require simple regular cleaning with products designed for glass. Use a soft lint free cloth for cleaning and polishing. Never use abrasive cleaners or pads on matte or glossy glass tiles.
Sanded or matte glass must be thoroughly degreased and cleaned with denatured alcohol using a soft lint-free cloth. Murphy’s oil soap can be used to restore the LUSTER on our sanded or matte surfaces. FilaCleaner for routine cleaning and PS87 for heavy duty cleaning and CR10 for vertical surfaces are excellent for Glass Tiles.
Our terra cotta tiles should always be sealed prior to GROUTING. Use PRW200 as a grout release prior to grouting. Re-sealing is required on a routine basis as a part of maintenance. FilaFOB solvent, MP90 Eco Plus, Stoneplus or Fila Wet are the recommended sealers.
Regular mopping with FilaCleaner will help to maintain the LUSTER and PATINA. We also recommend Fila’s waxes for maintenance and color enhancement.

Get to Know Your Stone
The first step in proper stone care and maintenance is to understand your stone’s geological classification and composition. This information will help you to identify what cleaning products to use and how best to care for your natural stone.
Natural stone is categorized into three basic geological classifications by their respective formation processes: Sedimentary, Metamorphic and igneous. Additionally, stones in each category can be either Calcareous or Siliceous. Calcareous stone is composed mainly of calcium carbonate, a chemical compound commonly found in natural stone, shells and pearls.
Calcium Carbonate is sensitive to acidic solutions so mild, non-acidic cleaners are recommended.
Siliceous stone, as the term implies, is one composed primarily of silicates, such as quartz, feldspar, mica, etc. as such, a siliceous stone is generally resistant to most acids found in kitchen settings, although acidic cleaners are still not recommended, as these stones may contain trace levels of minerals that are acid sensitive.
Easy Care Tips
To get the longest life and preserve the beauty of your natural stone, follow these simple tips:
Coasters: Use coasters under all glasses, particularly those containing alcohol or citrus juices.
Trivets: While many stones can withstand heat, the use of trivets or mats is recommended.
Dust Mopping: Dust mop interior floors frequently using a clean non-treated dry dust mop. Sand, dirt and grit are abrasive and can damage natural stone.
Mats/rugs: Mats or area rugs inside and outside an entrance will help to minimize the sand, dirt and grit that may scratch the stone floor. Be sure that the underside of the mat or rug is a slip resistant surface.
Vacuum cleaners: If used, be sure the metal or plastic attachments or the wheels are not worn as they can scratch the surface of some stones.
Spills: Blot the spill with a paper towel immediately. Don’t wipe the area, it will spread the spill. Flush the area with water and mild soap and rinse several times. Dry the area thoroughly with a soft cloth. Repeat as necessary.
- 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 rag mop on floors and a soft cloth for other 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.
- In outdoor pool, patio or hot tub areas, flush with clear water and use mild bleach solution to remove algae or moss.
- Many suppliers offer products used for stone cleaning.
- Products containing lemon, vinegar or other acids may dull or etch calcareous stones.
- Scouring powders or creams often contain abrasives that may scratch certain stones.
- 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.
Sealing is a common step taken on some stones as an extra precaution against staining. In fact, the sealing products used in the stone industry are ‘impregnators” which do not actually seal the stone, but more correctly act as a repellent rather than a sealer. Sealing does not make the stone stain proof, rather it makes the stone more stain resistant. When consulting with your stone supplier, you may find that many stones do not require sealing. However, applying an impregnating sealer is a common practice.
When considering sealing, remember that sealing the stone does not make the stone stain proof, it makes it more resistant to staining.
If a sealer is applied in a food preparation area, be sure that it is non-toxic and safe for use.
Consult with your supplier or sealing manufacturer specific to the type of sealer and frequency of use recommended.
Stain Identification Tips
identifying the type of stain on the stone surface is the key to removing it. Stains can be oil based, organic, metallic, biological, ink based, paint based, acid based. If you don’t know what caused the stain, consider likely staining agents that may have been present. Here are some questions you consider:
Where is the Stain Located?
- Is it near a plant, a food service area, an area where cosmetics are used?
- What color is it?
- What is the shape or pattern?
- What occurs in the area around the stain?
WHAT TYPE OF STAIN IS IT?
The following sections describe the types of stains you may have to deal with and the appropriate household chemicals to use and how to prepare and apply a poultice to remove the stain.
(grease, plumbers’ putty, tar, cooking oil, milk, cosmetics)
An oil-based stain will darken the stone and normally must be chemically dissolved so the source of the stain can be flushed or rinsed away. Clean gently with a soft, liquid cleanser with one of the following: household detergent, mineral spirits, or acetone.
(coffee, tea, wine, fruit, tobacco, paper, food, urine, leaves, bark, bird droppings)
May cause a pinkish-brown stain and may disappear after the source of the stain has been removed. Outdoors, with the sources removed, sun and rain action will generally bleach out the stains. Indoors, clean with 12% hydrogen peroxide (hair bleaching strength) and a few drops of ammonia.
(iron, rust, copper, bronze)
Iron or rust stains are orange to brown in color and follow the shape of the staining object such as nails, bolts, screws, cans, flower pots, metal furniture. Copper and bronze stains appear as green or muddy-brown and result from the action of moisture on nearby or embedded bronze, copper or brass items. Metal stains must be removed with a poultice. (See website on Using a Poultice –
www.marble-institute.com/consumers/poultices.cfm. Deep-seated, rustystains are extremely difficult to remove and the stone may be permanently stained.
(algae, mildew, lichens, moss, fungi)
Clean with diluted cleaning solution. Use a 1/2 cup of any of the following: ammonia, bleach, or hydrogen peroxide and a gallon of water. Reminder: do not mix bleach and ammonia.
(magic marker, pen, ink)
On light colored stones, clean with bleach or hydrogen peroxide. On dark colored stones, clean with lacquer thinner or acetone.
Small amounts can be removed with lacquer thinner or scraped off carefully with a razor blade. Heavy paint coverage should be removed only with a commercial “heavy liquid” paint stripper available from hardware stores and paint centers. These strippers normally contain caustic soda or lye. Do not use acids or flame tools to strip paint from stone. Paint strippers can etch the surface of the stone; repolishing may be necessary. Follow the manufacturer’s directions for use of these products, and flush the area thoroughly with clean water. Protect yourself with rubber gloves and eye protection, and work in a well-ventilated area. Use only wood or plastic scrapers for removing the sludge and curdled paint. Normally, latex and acrylic paints will not cause staining. Oil-based paints, linseed oil, putty, caulks and sealants may cause oily stains. Refer to the section on oil-based stains.
Water Spots and Rings
(surface accumulation of hard water)
Buff with dry 0000 steel wool.
Fire and Smoke Damage
Older stones and smoke or firestained fireplaces may require a thorough cleaning. When the smoke is removed, there may also be some etching (due to carbonic & other acids in smoke). Commercially available “smoke removers” may save time and effort.
(caused by acids left on the surface of the stone)
Some materials will etch the finish but not leave a stain. Others will both etch and stain. Contact your stone dealer or call a professional stone restorer for refinishing or repolishing etched areas.
(a white powder that may appear on the surface of the stone)
It is caused by the deposition of mineral salts carried by water from below the surface of the stone. When the water evaporates, it leaves the powdery substance. If the installation is new, dust mop or vacuum the powder. You may have to do this several times as the stone dries out. Do not use water to remove the powder; it will only temporarily disappear. If the problem persists, contact your installer to help identify and remove the cause of the moisture.
Scratches and Nicks
Slight surface scratches may be buffed with dry 0000 steel wool. Deeper scratches and nicks in the surface of the stone should be repaired and repolished by a professional.

Spills and Stains
Blot the spill with a paper towel immediately. Don’t wipe the area, it will spread the spill. Flush the area with plain water and mild soap and rinse several times. Dry the area thoroughly with a soft cloth. Repeat as necessary. If the stain remains, refer to the section in this brochure on stain removal.
Identifying the type of stain on the stone surface is the key to removing it. If you don’t know what caused the stain, play detective. Where is the stain located? Is it near a plant, a food service area, an area where cosmetics are used? What color is it? What is the shape or pattern? What goes on in the area around the stain? Surface stains can often be removed by cleaning with an appropriate cleaning product or household chemical. Deep-seated or stubborn stains may require using a poultice or calling in a professional. The following sections describe the types of stains that you may have to deal with and appropriate household chemicals to use and how to prepare and apply a poultice to remove the stain.
Making and Using a Poultice
A poultice is a liquid cleaner or chemical mixed with a white absorbent material to form a paste about the consistency of peanut butter. The poultice is spread over the stained area to a thickness of about 1/4 to 1/2 inch with a wood or plastic spatula, covered with plastic and left to work for 24 to 48 hours. The liquid cleaner or chemical will draw out the stain into the absorbent material. Poultice procedures may have to be repeated to thoroughly remove a stain, but some stains may never be completely removed.
Poultice materials include kaolin, fuller’s earth, whiting, diatomaceous earth, powdered chalk, white molding plaster or talc. Approximately one pound of prepared poultice material will cover one square foot. Do not use whiting or iron-type clays such as fuller’s earth with acid chemicals. The reaction will cancel the effect of the poultice. A poultice can also be prepared using white cotton balls, whitepaper towels or gauze pads.
Cleaning Agents or Chemicals
Poultice with baking soda and water OR one of the powdered poultice materials and mineral spirits.
Poultice with one of the powdered poultice materials and 12% hydrogen peroxide solution (hair bleaching strength) OR use acetone instead of the hydrogen peroxide.
Poultice with diatomaceous earth and a commercially available rust remover. Rust stains are particularly difficult to remove. You may need to call a professional.
Poultice with one of the powdered poultice materials and ammonia. These stains are difficult to remove. You may need to call a professional.
Poultice with dilute ammonia OR bleach OR hydrogen peroxide. DO NOT MIX AMMO-NIA AND BLEACH! THIS COMBINATIONCREATES A TOXIC AND LETHAL GAS!
