Your Granite sink is manufactured to the highest possible standards. To maintain its good looks, Franke recommend that you follow these simple guidelines.
Most deposits can be removed with washing up liquid and hot water followed by a clean water rinse. It is also good practice to then dry the sink with a soft cloth, as otherwise limescale can build up on the surface.
For more stubborn marks, it is recommended that your use a cream or powder cleaner design for cleaning kitchen surfaces. This is applied to the surface of the sink and scrubbed into a paste with a Scotchbrite® pad before rinsing off with clean water. The Scotchbrite® pad will not damage the sink surface.
The quality of your water can affect the good looks of your sink by giving the appearance of staining. This “staining” is generally a build up of limescale or similar mineral deposits within your water supply; this is particularly prevalent in hard water areas.
Limescale is the natural minerals that are contained within all drinking water. These minerals appear on the surface of all products where the water is in contact and allowed to dry naturally. As the water evaporates naturally through time, the mineral deposits within liquid cannot disappear so they are then left behind on the surface. Limescale readily absorbs staining agents such as tea, coffee, and red wine and can change the appearance from normal white. For this reason, always rinse and dry your sink after each occasion that you use it to avoid the mineral deposits being left behind.
To remove any limescale that has built up on the surface of your sink, try a limescale remover available from hardware or DIY stores. Alternatively, a natural remedy to this problem is to soak the affected area in a solution of hot water and white vinegar (not brown); three parts water to one part vinegar. This will loosen the scale, making it easy to scrub it away with an abrasive pad and kitchen sink cleaner. The area should then be rinsed thoroughly and dried to stop the build up starting again.
Other specific problems and recommended treatments
Your Granite sink is made from extremely hard wearing material. Any metal pots, pans or cutlery dragged across the surface will initially leave marks on the surface. These marks are in fact metal deposits from the metal pots, pans or cutlery that were dragged across the sink surface. These can easily be removed by scrubbing them away with an abrasive pad and kitchen sink cleaner.
If a “stain” has become deeply ingrained, and cannot be removed by the methods outlined above then soak the area overnight in a solution of 40 parts water and 1 part bleach or biological washing powder. Drain this after eight hours and rinse thoroughly with clean water. NOTE – this should not be used as a routine cleaning method.
** Do not forget – always finish off by rinsing your sink thoroughly with clean water to remove any residue, and then dry it with a soft cloth to prevent build up of limescale.
Take care to avoid the following
Leaving bleach or cleaning agents containing bleach on your sink surface for any length of time. Many of the general cleaning agents contain bleach, including a number of the new “trigger-dispense” products, most domestic dishwasher liquids and some multi-purpose cream cleaners.
If bleach is necessary, e.g. to clean the overflow or waste outlet, squirt directly into the hole and leave for 2 to 3 minutes only, then rinse thoroughly with clean water. Under no circumstances allow the bleach to be in contact with the sink surface for longer than 30 minutes as long appearance of the sink will be affected.
Try to avoid dropping sharp objects into the sink as they may chip or damage the surface. They are also likely to be damaged by the hardness of the sink.
Do not leave wet cleaning aids such as cloths or sponges on the sink surface as these all hold water and when this evaporates it allows limescale to be deposited.
A Guide to Use and Care of Granite Sinks - Do's & Don'ts
These sinks are made of an innovative material that bonds fine granite particles in a polymer matrix. This technologically advanced material is designed and manufactured to withstand the rigors of everyday household use. The following care and cleaning instructions will keep your KINDRED Granite sink a beautiful focal point in your kitchen for many years.
- The best form of maintenance is frequent, regular cleanings. A little bit of cleaning on a regular basis is preferable to a major cleaning on a sporadic basis.
- The best method of preventative maintenance is to ensure that the sink is clean and dry when not in use. Rinse and towel dry the sink after each use in order to minimize major cleanups. (This is particularly appropriate where water may have a high mineral content.)
- Keep the sink fixture free of any standing water which may build up mineral deposits. The quality of your water can affect your sinks appearance (particularly a designer color such as Jade) and this water quality will vary from household to household.
- Should a mineral deposit build up over time, use vinegar to remove the deposit and follow this by flushing the surface with water.
- To clean your sink, use the mildest procedure that will do the job effectively.
- Use a damp cloth, or sponge with a solution of dishwashing liquid to remove everyday stains from your sink.
- More stubborn stains can be removed by scrubbing with an abrasive pad such as ScotchBrite, or any mild abrasive cleanser such as Ajax. (Granite sinks only)
- If a stain becomes engrained in the bowl, mix a solution of 40 parts water with 1 part bleach (or biological washing powder), and soak the bowl surface overnight. Then drain and rinse thoroughly with water. This is not to be used as a routine cleaning.
- Your Granite sink is made from an extremely hard and tough material. Any metal pots or pans dragged across the bottom of the sink will leave a metal residue. This marking is actually on the surface of the sink and can be removed by scrubbing in a circular manner with a soft nylon brush and a liquid soap.
- Try to avoid dropping sharp objects into the sink as they may damage the surface. We recommend using wire bottom grid accessories to avoid this type of damage.
- Always avoid the use of metal scouring pads, or wire wool, as they will leave a metal residue on the surface of the sink. Over time these minute particles will rust and then give the appearance that the surface of the sink has stained.
- Do not leave any mild steel or cast iron cookware or implements anywhere on the sink for extended periods of time. The combined presence of iron and moisture can only lead to staining of the sink.
- Do not leave rubber dish mats, wet sponges, or cleaning pads in the sink overnight as they will trap water which could lead to staining and discoloration of the sink surface.
- Do not let concentrated bleaches or products containing chlorinated solvents (paint strippers) or products containing formic acid (drain cleaner or kettle descaler) come into contact with the surface of the sink. They may cause discoloration.
- Any accidental contact with these materials should be addressed by an immediate cleaning and rinsing of the sink.
- Granite has a high heat resistance of 536ºF (280ºC) and will be virtually unaffected by brief exposure to objects at this temperature. However, we do not recommend that the sink be used as a cooling place for hot objects ...please use a separate insulated board or tray for that purpose.
- Do not use your sink as a cutting surface. KINDRED offers hardwood cutting boards for this purpose.
