FAQ

Although granite is quite resistant to scratches, to properly maintain this type of countertop material, it’s advisable to follow a few simple procedures.

  1. Spills have a tendency to soak into the surface, so to avoid deep staining wipe up spills immediately.
  2. For stone surfaces a neutral cleaner, such as stone soap or mild dishwasher liquid and warm water, is safe to use.
  3. When cleaning with a soap solution, use a soft, clean cloth and then rinse the surface thoroughly. Finish off by drying with a soft, clean cloth.
  4. If you do happen to stain the surface, removal depends on the type of stain. First, try removing it with this paste: mix together a cup of flour, 1-2 tablespoons of dishwasher liquid, and water. Place the paste over the stain, cover in plastic wrap, and leave overnight. In the morning, use a wooden utensil to scrape away the paste and give it a rinse. This should work except for stains made from grease, oil, or milk. In these cases, instead of dishwasher liquid use hydrogen peroxide in the paste, or ammonia.
  5. For organic stains resulting from coffee, tea, or fruit, a mixture of 12% hydrogen peroxide combined with a few drops of ammonia should work wonders.
  • Ink, marker and wine stains on darker stone require a lacquer thinner or acetone for removal. Hydrogen peroxide works well on light-colored granite.
  • Another method to remove wine, ink, or any other non-oil stain is to mix molding plaster and pure bleach into a paste. Apply for 30 minutes, remove, and rinse.
  • For oil-based or fat-based stains, create a paste of molding plaster and water. Apply an even layer over the stain for 3 hours, after time has expired remove and rinse surface.
  • Granite countertops require resealing every two to three years, but ask your installer for suggestions as to when this needs to be done.
  • Of course, on surfaces that will be used for food preparation, use a non-toxic sealer.
  • New disinfectant cleaners on the market now come in formulas designed for granite countertops; purchase this type of product if you prefer disinfectant cleaners to other cleaning options.
  • For any problem that you can’t handle on your own or are not familiar with, call a professional to handle the cleaning job.
  • Use coasters, especially for alcoholic and citrus beverages, as the acid in these drinks can dull the stone’s surface.
  • Always test these cleaning methods on small discreet area for color fastness or granite damage.
  • There are also new products for removing stains in hardware stores, like Home Depot and Lowes. However, always follow the instructions provided on the products label.
Because natural stone is porous, it is recommended that a sealant be applied to the surface of the stone to help protect its natural properties. Most granite companies use surface sealants that they claim protect against staining by creating a barrier that sits on top of the stone, resisting substances from penetrating into the pores. This is cost-effective for fabricators, but not ideal for homeowners for three main reasons. Surface sealants wear off and require constant re-sealing (at least twice a year). Surface sealants can give the stone a cloudy appearance. Sunlight and the fact that the stone is unable to breathe through the pores can cause the sealant and/or the stone to change colors over time.
Care and Maintenance 

Caring for your Cambria investment is easy. Our quartz countertops never require sealing, polishing, or reconditioning and are stain resistant. Just use a little warm water, soft cotton cloth, and mild soap, if desired. 

Surface Damage

We make Cambria products to be durable-though any surface can be damaged or chipped in wrong circumstances. Hitting edges around sinks and dishwashers could cause chips. Cutting on a Cambria surface could show scratch marks on our more monotone designs. It is best to always use a cutting board.

Heat

Sudden or rapid temperature changes near edges or prolonged exposure on top could damage natural stone surfaces. We recommend you use a closed-weave hot pad or solid trivet such as a breadboard under pots and pans, electric frying pans or griddles, slow cookers, air fryers, roaster ovens, and heat lamps.

Stain Resistance

Cambria quartz countertops are nonporous and nonabsorbent—making them resistant to stains, reducing potential for bacterial growth, and eliminating the need to seal. Any residue can be simply removed with warm water, a soft cotton cloth, and mild soap, if desired.

What to Avoid

Take the following precautions to keep your countertops in optimal condition.

1. Do not expose, in use or otherwise, Cambria Product to abrasive, strong alkaline, acid, free radicals, oxidizers, or cleaners of the like (whether high, neutral, or low pH). Various chemicals are corrosive and/or erosive in their ability to attack any surface, including Cambria Product. Be very aware of these potential damages to its surface.

2. Cambria is not heat-proof, chemical-proof, or fracture-proof in any form. Be aware of damaging exposure to these potentially damaging acts. 

3. Do not use or expose Cambria Product to certain cleaning products, including, but not limited to, bleach, oven cleaners, Comet®️, Soft Scrub®️, S.O.S.®️ pads, products with pumice, batteries, paint removers, furniture strippers, tarnish or silver cleaners, or the like. 

4. Do not use abrasive or harsh scrub pads and do not apply any sealers, penetrants, or topical treatments to Cambria Product under any circumstances. Such products will wear off and cause the gloss to appear dull or inconsistent.
