Stones Are Porous
All stones, due to their granular
construction, are porous to a greater or lesser extent
and most granites fall into the latter category. To reduce
the slight ability of granite to absorb liquids, the
surface is treated with a proprietary sealer that penetrates
the surface and fills the microscopic voids between the
crystals. This process is done in the factory at the
completion of manufacture and again when installed.
We recommend that you re-seal
granite every 6 month to 1 year, depending on the use
and porosity of the stone. Marble, Limestone and other
natural stones will also have to be re-sealed every year.
With the lighter coloured granite
you may notice a slight darkening of the stone in areas
where water has been allowed to stand, but this should
fade away as it dries out.
While Granite is highly stain
resistant, substances such as oils, grease, and products
that contain these substances can stain or darken your
granite if not wiped up quickly.
Other natural stones other than
granite have a much higher chance of staining. Please
use the utmost care and wipe up spills immediately.
You can purchase specially formulated
Stain Remover Products to take extra care of your stone
and remove unwanted stain professionally..
Acids and Alcohol
Marble and Limestone are susceptible
to the aggressive action of acids and alcohol. Care should
be taken to remove spillage of fruit juice, particularly
lemon, wine and vinegar, beetroot etc., e.g. the residue
of red wine on the base of wineglasses will leave its
mark. Nail varnish and any other solvent or oil based
products will stain if not wiped up immediately.
Materials not to be used on Granite:
Formic acid, Hydrofluoric acid, Nitric acid, Sulphuric
acid, Phosphoric acid, Hydrochloric acid.
We recommend that you clean your
granite worktops with either a mild soap (or a non-abrasive
light neutral detergent (PH7)) and water or a cleaner
specifically made for stone surfaces (please view our
stone care products for more information). To dry your
granite, you can use a chamois leather or similar. Drainer
Grooves can be cleaned using a wire wool.
Do not use glass cleaner to clean
marble, travertine, slate, limestone or onyx under any
Scratching and Chipping
Under normal use Granite should
not scratch or chip. It is safe to occasionally cut and
slice on your worktops. However, we recommend using a
cutting board to keep from dulling your cutlery. Dragging
very heavy objects, such as a tool box with dirt, grit
or sand on its bottom may cause the granite to scratch.
Pots and Pans taken directly from
your oven or stove top can be places directly onto your
granite worktops. Burning or marring will not occur.
Natural stones other than granite are not heat resistant.
Marble, Travertine, Onyx and Limestone
are highly porous materials that can stain, scratch,
etch, chip and crack if not taken care of properly.
