With the correct care and maintenance regime, your stone investment will achieve great longevity.
Stones Are Porous – Sealing
All stones, due to their granular construction, are porous to some extent. To reduce the slight ability of granite to absorb liquids, the surface is treated with a sealant which penetrates the surface and fills the microscopic voids between the crystals. This process is performed in our workshops at fabrication and again, if necessary, after installation. Different granites can be more or less porous – please ask about the frequency of re-sealing required for your choice of stone.
With the lighter coloured granite types, 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. Substances such as oils, grease, and products that contain these substances can stain or darken your granite if not wiped away quickly. Other natural stones like marble are more susceptible to staining. Please use the utmost care and wipe away spills immediately.
Acids and Alcohol
Marble is susceptible to the aggressive action of acids and alcohol. Care should be taken to remove spillage of fruit juice, particularly lemon, wine and vinegar and beetroot etc. For example, the residue of red wine on the base of a wineglass will leave a mark if not removed quickly. Nail varnish and any other solvent or oil based products will stain if not wiped up immediately. Materials not to be used on granite are: formic acid, hydrofluoric acid, nitric acid, sulphuric acid, phosphoric acid and hydrochloric acid. These acids will damage your stone. NB: Do not use glass cleaner to clean marble, travertine, slate, limestone or onyx under any circumstances.
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 prevent the blunting of your cutlery. Dragging very heavy objects, such as a tool box with dirt, grit or sand on its bottom, or a heavy bag with metal feet, may cause the granite to scratch.
We recommend that you clean your granite with either a mild soap (or a non-abrasive light neutral detergent with a PH of 7) and water or a cleaner specifically made for stone surfaces. To dry your granite, use a chamois leather or similar. Drainer Grooves can be cleaned using a wire wool.
