Deep cleaning of grout and tile
State of the art equipment and a revolutionary process restores the clean, crisp natural beauty of your tile and grout, safely and gently. This process should be done every two to three years; depending on traffic. We also recommend grout be sealed at the time of cleaning to prolong the life and cleanliness of the grout.
Cleaning Your Granite and Engineered Stone
Do not use general purpose cleaners on your granite or you may damage your stone or the sealant. We have a full-line of cleaners, some with antimicrobial protection that we recommend for cleaning granite. These cleaners are developed specifically for natural stone and tile care. Their unique blend of neutral cleaning agents are gentle to your stone.
Cleaning Marble, Limestone and Travertine
Many common foods and drinks contain acids that may etch or dull the stone surface. Also, some toiletries (e.g. perfume, toothpaste, and mouthwash) may damage the stone surface or degrade the sealer. Do not use general purpose or soft scrub cleansers. Gramar Stone Center, Inc and industry professionals, recommend a pH balanced cleaner. Additionally, a cleaner that also contains a sealer will help to extend the life of your stone.
At home maintenance guidelines for all types of natural stone surfaces
Marble, granite, travertine or natural stone shower:
Daily: Wipe shower walls and floor down with a squeegee to remove most soap scum and water. Dry any areas where water might puddle with a towel.
Weekly: Use a squeegee to wipe down entire shower. Next, spray disinfecting shower cleaner onto walls (one wall at a time) and wipe dry with a towel. Repeat process for all walls and floor.
Yearly or bi-yearly: Once natural stone tiles loose luster, become pitted, have permanent water streaks or look worn, it is time to call a professionally trained stone technician restore your shower back to its’ original condition.
Marble, granite, travertine or natural stone floor:
Weekly: Once a week, your natural stone floor should be dust mopped with a cotton dust mop (12” - 18” wide head). In week 2, your natural stone floor should be mopped with a cotton string mop and a stone soap solution consisting of 2 gallons of warm clean water and 6 - 8 oz of stone soap (pH7). Mop floor with a damp (well wrung out) mop of this solution. Be careful not to subject floor to too much water. Allow floor to air dry.
Yearly or bi-yearly: When floor becomes dull, looses its luster, numerous scratches appear and water spotting occurs, it is time to call a professionally trained stone technicians to restore your floor back to original condition.
Marble, granite or natural stone countertops:
Daily: Wipe off debris with a dry paper towel. After large debris has been removed wipe down entire countertop with either a 1.) Natural stone, anti-bacterial safe wipe (or) 2.) Natural stone soap and a clean damp paper towel.
Note: All countertops should be cleaned with a neutral stone soap (pH7) to prevent long term damage to your stone investment.
Every 2 to 3 years (granite countertops): Countertops should be re-sealed to guard against staining, create easier wipe-up, strengthen countertops and preserve their natural beauty.
Yearly or bi-yearly (marble, limestone or travertine countertops): As countertops loose their luster, become water and chemically spotted a professionally trained stone technician needs to be called in to restore countertop back to original condition.
Tile and grout (ceramic, porcelain and most other man made materials):
A couple times weekly: Sweep floor free of debris (dirt, dust and sand) into dustpan.
Weekly: Mop floor with a damp (not too wet) cotton string type mop combined with a high alkaline cleaner and hot water. Follow instructions on alkaline cleaner for proper mixing ratio. Change mop water as soon as it appears to have a brown color.
Yearly or bi-yearly: If grout on floor begins to become permanently discolored, it is time to call a professionally trained stone technician to have it professionally cleaned to restore grout and tile back to original condition.
Natural Stone Stains Removal
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.
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.
Types of Stains and First Step Cleaning Actions
OIL-BASED
(grease, 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 bleach OR household detergent OR ammonia OR mineral spirits OR acetone.
ORGANIC
(coffee, tea, 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, normal sun and rain action will generally bleach out the stains. Indoors, clean with12% hydrogen peroxide (hair bleaching strength) and a few drops of ammonia.
METAL
(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 section on Making & Using a Poultice) Deep-seated, rusty stains are extremely difficult to remove and the stone may be permanently stained.
BIOLOGICAL
(algae, mildew, lichens, moss, fungi)
Clean with diluted (1/2 cup in a gallon of water) ammonia OR bleach OR hydrogen peroxide. DO NOT MIX BLEACH ANDAMMONIA! THIS COMBINATION CREATES A TOXIC AND LETHAL GAS!
INK
(magic marker, pen, ink)
Clean with bleach or hydrogen peroxide (light colored stone only!) or lacquer thinner or acetone (dark stones only!)
PAINT
Small amounts can be removed with lacquer thinner or scraped off carefully with a razorblade. 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; re-polishing may be necessary. Follow the manufacturer's directions for use of these products, taking care to 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 fire stained fireplaces may require a thorough cleaning to restore their original appearance. Commercially available "smoke removers" may save time and effort.
ETCH MARKS
Etch marks are 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. Once the stain has been removed, wet the surface with clear water and sprinkle on marble polishing powder, available from a hardware or lapidary store, or your local stone dealer. Rub the powder onto the stone with a damp cloth or by using a buffing pad with a low-speed power drill. Continue buffing until the etch mark disappears and the marble surface shines. Contact your stone dealer or call a professional stone restorer for refinishing or re-polishing etched areas that you cannot remove.
EFFLORESCENCE
Efflorescence is a white powder that may appear on the surface of the stone. It is caused by water carrying mineral salts from below the surface of the stone rising through the stone and evaporating. 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 re-polished by a professional.
Poultices
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
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
OIL-BASED STAINS
Poultice with baking soda and water OR one of the powdered poultice materials and mineral spirits.
ORGANIC STAINS
Poultice with one of the powdered poultice materials and 12% hydrogen peroxide solution (hair bleaching strength) OR use acetone instead of the hydrogen peroxide.
IRON STAINS
Poultice with diatomaceous earth and a commercially available rust remover. Rust stains are particularly difficult to remove. You may need to call a professional.
COPPER STAINS
Poultice with one of the powdered poultice materials and ammonia. These stains are difficult to remove. You may need to call a professional.
BIOLOGICAL STAINS
Poultice with dilute ammonia OR bleach OR hydrogen peroxide. DO NOT MIX AMMO-NIA AND BLEACH! THIS COMBINATIONCREATES A TOXIC AND LETHAL GAS!
Applying the Poultice
Prepare the poultice. If using powder, mix the cleaning agent or chemical to a thick paste the consistency of peanut butter. If using paper, soak in the chemical and let drain. Don't let the liquid drip.
Wet the stained area with distilled water.
Apply the poultice to the stained area about1/4 to 1/2 inch thick and extend the poultice beyond the stained area by about one inch. Use a wood or plastic scraper to spread the poultice evenly.
Cover the poultice with plastic and tape the edges to seal it.
Allow the poultice to dry thoroughly, usually about 24 to 48 hours. The drying process is what pulls the stain out of the stone and into the poultice material. After about 24 hours, remove the plastic and allow the poultice to dry.
Remove the poultice from the stain. Rinse with distilled water and buff dry with a soft cloth. Use the wood or plastic scraper if necessary.
Repeat the poultice application if the stain is not removed. It may take up to five applications for difficult stains.
If the surface is etched by the chemical, apply polishing powder and buff with burlap or felt buffing pad to restore the surface.
