CLEANING PROCEDURE - CAMBRIA® NATURAL QUARTZ SURFACE

Overview - Cambria® Natural Quartz Surface

 Cambria is created from pure natural quartz,

an extremely hard stone crystal mined di­rectly from the earth. In fact, quartz is the
hardest non-precious stone to be found in
the earth's surface.

 Cambria is non-porous, making cleanup easy

and preventing food and moisture from
penetrating its surface (the main source of

growth for harmful bacteria).

 Cambria has been certified by NSF International for use as a food

preparation surface.

Cleaning - Cambria® Natural Quartz Surface

Clean as often as desired with warm water and a pH neutral, non-abrasive
cleaner such as Formula 409® or Simple Green®. Rinse with clear , clean
water. No sealing, buffing or re-polishing is necessary.

Other guidelines to observe:

 For dried spills, use a wet cotton cloth.
 Avoid bleach, alkaline (high pH) cleaners such as oven cleaner, abrasive

cleaners such as Comet®, Soft Scrub® products, or other products
containing pumice, SOS® pads, and other similar products, paint removers,
furniture strippers, tarnish or silver cleaners or the like.

 Do not apply any sealers, penetrants or topical treatments to Cambria®

under any circumstances.

 Natural stone surfaces can be damaged by sudden and rapid change of

temperature especially near the edges, as well as direct or sustained heating
of the top.

 Cambria® may not withstand the direct transfer of heat from pots and pans

and other cooking units such as electric frying pans and griddles, and some
crock-pots or roaster ovens and heat lamps. Therefore, the use of a hot pad
or trivet is always recommended.

 Cambria® will resist stains from fruit juices, food coloring, coffee, tea, wine,

grape juice, nail polish and felt tip markers.

For Daily, Routine Cleaning:

Silestone® requires very little maintenance. Simply wipe your Silestone surface with soap and warm
water on a regular basis to maintain its beauty and shine for years to come. Any pH balanced
general-purpose household cleaner may be used (e.g. dish soap, Windex®).

For Difficult Spills:

To remove difficult spills, wipe the surface with warm water and soap. If needed, apply a common
household cleaner. For stains that harden as they dry, such as food, gum, nail polish, and paint,

water and soap. Gray marks lefts by the razor, can be wiped away with soap and water. Silestone®'s
advanced technology makes its surface extremely resistant to damaging chemicals. Difficult spots may
be treated with one of the cleaners listed below. Leave the cleaner to sit for up to 10 minutes. Scrub
and rinse thoroughly.

 Acetate
 Lacquer Thinner
 Rubbing Alcohol
 Ammonia

Extreme Heat Protection:

Silestone® is extremely resistant to heat, and can withstand moderately high temperatures for brief
periods of time without being damaged. Although Silestone® is more heat resistant than any other
stone surface, all stone can be damaged by sudden and extreme temperature changes, especially
near the edges. For this reason, it is recommend that a trivet or a hot pad be used to protect the
Silestone® surface from extreme heat.

 Mineral Spirits
 Vinegar
 Formula 409®
 Paint Thinner
