A hole has appeared in my stainless steel sink why?

Pitting corrosion of stainless steel is generally due to the steel being in contact with strong acids, bleaches or sterilising products that have chloride in them. The stronger the chemical and the longer the exposure, the more the steel will be damaged. Once pitting has occurred the damage cannot be reversed.

Avoid bleaches containing Hypochlorite. There are certain foods that when left for long periods, can cause pitting and corrosion. Examples include fruit juices, salt, vinegar, mustard's, pickles, and mayonnaise.

To avoid pitting, rinse the steel surface thoroughly with clean water after contact with such chemicals.

Can l buy accessories and cleaning product from Astracast?

Product can be purchased from our Astracast Direct website or for items not available on the website, by contacting us on telephone number 01274 475160.

Can l use a waste disposal system on and Astracast sink?

Yes, however if fitting with a ceramic sink you may need to purchase an adaptor due to the thickness of the sink. These can be purchased from Astracast.

Waste disposal systems can not be used with our Vantage, Orb, Geo, Sudbury, Ceramic Belfast, Onyx drainer, or the half bowl in the Lincoln Ceramic 1.5 Bowl undermount due to the unique size or shape of the wastes in these sinks.

How do l care for my ceramic sink?

To keep the sink's stunning appearance the following guidelines must be followed, failure to do so may result in damage of the product:

  • Strong chemicals and alkalies such as ammonia, caustic soda, paint strippers, brush cleaners and nail varnish removers must not come into contact with the sink because they can cause damage.
  • Please take care not to drop any objects e.g. knifes from an excessive height as this may chip or crack the surface glaze.
  • Do not place hot pans straight from the cooker onto the sink as this may cause crazing to the surface finish.
  • Ceramic sinks can be cleaned with most cleaners, including mild abrasives. Metallic pan scrubbers are not recommended as metal on ceramic can cause grey marks. These grey marks can also be caused by pans and cutlery, they can be removed by a mild abrasive cleaner (i.e. kitchen cleaner that contains maximum 5% bleach only) and a non-metallic pan scrubber. Bleach can be used on the sink, but please ensure sink is rinsed thoroughly.
How often do l need to change the filter on my Springflow® Tap?

A Springflow® tap treats up to 2,500 litres of water, around six months use, with just one Springflow® cartridge

How should l care for my wooden chopping board?

All the boards we supply are treated, however, we recommend that before use the board should be wiped all over with a little vegetable oil. This should be repeated every few months to keep the board in good condition. After using the board, rinse it using a damp cloth and store the board flat. 

The board will warp if it is allowed to stand in water or it is not treated regularly. If warping occurs re-treat and position the board flat.

Tap Cleaning Instructions

Do's

  • Clean with a mild non-abrasive liquid detergent or soap and water.  Dry with a clean soft cloth.

Dont's

  • Don't use cleaners that contain bleach.  If the cloth used to clean the tap has previously been used with a cleaner that contains bleach, take special care to thoroughly rinse the cloth with clean water before use.
  • Don't use abrasive cleaners or abrasive cloths.
  • Bleach and abrasives will discolour or damage the tap coating, and will invalidate the guarantee.

 

Is water pressure important when choosing my tap?

Your tap must be compatible with your water supply some High pressure taps will not be compatible with a gravity fed water system and it will cause issues with the function of the tap as the product is not working on a balanced system.

Please ensure you discuss the options with your tap supplier before purchasing a tap.

Have a read of our blog post 'Why is tap pressure important?' for more information.

l have rust marks on my sink why?

18/10 304 austenitic stainless steel, as used almost exclusively by all kitchen sink manufacturers, cannot in itself rust. It is however, possible for small particles of ferrous metals to become embedded in the surface of the stainless steel and it is these that exhibit the rusting. These particles could be as a result of, Steel wool style cleaning pads, steel cutlery, metal cooking implements or metal cans amongst others.

To remove this surface corrosion on the bowls of a matt/brushed steel sink, we recommend the use of a cleaning product called Bar Keepers Friend. If for use on a polished style stainless steel sink we recommend a product called Shiny Sinks.

Place a small amount of the product on a dry or damp cloth and rub in the direction of the grain of the sink, rinse the sink thoroughly and towel dry it may take several continuous applications before the corrosion has been fully removed.

What are the care and maintenance instructions for a granite sink?

Astracast ROK® Granite sinks are very tough and resilient. To keep the sink's stunning appearance the following guidelines must be followed, failure to do so may result in damage of the product:

  • The use of a plastic washing-up bowl is not recommended. Baskets are available for both the bowls of the sink and the drainer to help reduce the risk of damage and extend the working life of the sink.
  • Strong chemicals and alkalies such as ammonia, caustic soda, paint strippers, brush cleaners and nail varnish removers must not come into contact with the sink because they can cause damage to the sink.
  • Avoid dropping sharp objects onto the surface of the sink as these may damage the surface.
  • Do not place hot pans straight from the cooker onto the sink as this may cause some discolouration to the surface finish.
  • Heavy stains such as dyes and juices should be washed off as soon as possible.  Any remaining stubborn stains can be cleaned using a lightly abrasive cleaner which contains maximum 5% bleach, which should be applied to the affected area, and then rubbed with a non-metallic pan scrubber.  If the stains become ingrained in the bowls, an overnight soak using diluted bleach (1 part bleach to 10 parts water) or diluted biological washing powder will remove the marks easily.
  • The recommended way to clean the sink is by washing down with soap or detergent and warm water, ideally after use.  The surface can be wiped with a clean soft cloth. This procedure, if carried out correctly should be sufficient to keep the sink surface clean and stain free.
  • Limescale deposits can be removed by overnight soaking in a 1 part vinegar to 5 parts water solution or the product Limelight. Alternatively you can purchase a product from Astracast called "Astraclean" on our direct website or by telephone 01274 475160.
  • ROK® Granite sinks are harder than most metals and under certain circumstances aluminium pans may leave a grey mark on the surface of the sink. This is not permanent. It is a deposit of metal from the saucepan which can easily be removed by cleaning with a mild abrasive (see above).
What contaminates are removed by the filter?

What gauge of stainless steel does Astracast use for their sinks?

Stainless steel 18/10

What is head pressure and how does it effect Astracast taps?

Head pressure is a term used to define the amount of water pressure that is available.
In simple terms, if a tank of water is connected to a tap and the vertical distance between the tank and the tap is 10m (ie. a 4 story building) the pressure would be approx. 1 bar.

1m vertical distance approximates to 0.1 bar.

The greater the vertical distance between the tank and the tap the better the flow will be.

Some Astracast taps are only suited to high pressure (combination boiler) systems an example of this is the Finesse Flexi which requires a minimum of 10m head (1.0 bar) to operate correctly.

Have a read of our blog post 'Why is tap pressure important?' for more information.

Where can l buy Springflow® filters?

Products can be purchased from our Astracast Direct website. Alternativley you can contact us on 01274 475160.

Why do l have water marks on my stainless steel sink?

When water is left standing anywhere on a stainless steel sink, it will dry and leave a film on the surface of the steel. This film can be removed using everyday washing up liquid and a soft cloth ensure you rinse thoroughly and towel dry. To remove heavier residue you can use a mild solution of vinegar and water but ensure you rinse the solution thoroughly away from the sink and towel dry.

Why has my stainless steel sink scratched?

All stainless steel sinks will scuff and scratch in everyday use. The amount of scratching will depend on how the sink is used but it will look better with time due to the fact the scratching will have evened out.

We do not recommend using a plastic washing-up bowl as dirt can get stuck to the bottom of the bowl and this will scratch the sink. Matching baskets and grids are available for both the bowls of the sink and the drainer to help reduce the risk of damage and extend the working life of the sink.

Avoid using aggressive abrasive cleaners, wire wool or steel pads, as these will spoil the surface appearance of the sink. Avoid dropping sharp objects onto the surface of the sink as these will dent the surface. Please do not use the drainer as a chopping board, this will damage both the sink and the knife.
