Information & Care of Stainless Steel Sink

1) What is Stainless Steel?

  • A steel must have a minimum of 10.5% chromium content (by weight) to be classified as ‘Stainless Steel’
  • It is this chromium content that sets stainless steel apart from other steels to make it corrosion resistant

    2) Why Stainless Steel is selected to produce kitchen sink?

  • The main factor for selecting stainless steel is its corrosion resistance property
  • Stainless steel is initially considered an expensive material. However, experience has shown that using a corrosion resistant material avoids costly maintenance and replacement. Thus, these benefits make stainless steel more economical in the long run – which far outweighs the higher initial material cost
  • Stainless steel is recyclable
  • 3)Why Stainless Steel is corrosion resistant?

  • The common resistance of stainless steel arises from the self-repairing chromium oxide film that forms naturally on the surface of the steel. This self-repairing oxide film is present due to chromium
  • Although stainless steel can be easily scratched (like all other steels), these scratches do not reduce its corrosion resistance. This is due to self-repairing film which forms naturally on the surface of the stinless steel
  • The sink’s surface must be kept clean and dry at all times to allow adequate supply of oxygen to maintain this self-repairing oxide film
  • 4)Complaint of ‘Rusty’ Sinks

  • It is important to note that stainless steel sinks do not rust at all
    (Note: Your pots, knives & spoons are made of stainless steel and they do not rust, right?)
  • The appearance of rust marks on the sink is due to the rusting of foreign iron particles (non-stainless steel) – giving the false impression that the sink is rusting
  • The common causes of ‘rusty’ sinks are usually due to:
  • a) Rusting of iron particles from works performed during construction & renovation
    b) Acid attacks from acid wash of kitchen wall tiles during construction & renovation
    c) Vapor of strong acidic/alkalis household cleaning solutions stored under the sink
    d) Residue of high concentration of salt and vinegarleft on the sink after cooking
    e) Rusting of frying pans & steel wool (non-stainless steel type) left overnight in the sink

    Information & Care of Stainless Steel Sink

    5) Condensation Beneath The Sink

  • Condensation is a climatic phenomenon – where water vapor (gaseous state) in the air is returned to its original liquid form (physical state)
  • It occurs when warm moist air meets a cold surface (two different temperatures involved). The warm air is cooled to its dew point and below, causing water vapor in it to condense out into water
  • Here are some 3 good illustrations of condensation:
    a) A can of soft drink taken out of a fridge and left on the table on a warm day, Condensation will form on the surface of the can within minutes
    b) The formation of fog during cold weather, when warm wind passes over cold sea
    c) Taking a hot shower in cold weather, condensation will form on the bathroom mirror or shower screen

  • Likewise in kitchen sinks, condensation will form at the base of the sink when the air temperature inside the kitchen cabinet is warmer than the air temperature above the sink
  • The use of louver cabinet door is best recommended to ensure good ventillation inside the cabinet
  • Defrosting of frozen food on the sink will accelerate condensation – even on composite granite sinks. So, do defrost your food outside the sink
  • Here take good note that all brands and makes of kitchen sink are affected by this condensation phenomenon
  • 6) Watermark Stain

  • Watermark stains are the result of lime scale (minerals) deposits in the water supply, They create a ‘rainbow’ effect on the surface of the sink
  • The hardness of the water determines the extent of such stains
  • To reduce these unsightly marks, do dry the sink thoroughly after each washing
  • 7) Daily Care

  • Regular cleaning will enhance the good performance and long service life of the sink
  • The surface of the sink must be kept clean and dry at all times to allow adequate supply of oxygen to maintain the self-repairing ‘passive’ oxide film
  • 8) General “Do & Don’t”
    ✓ Do wash your kitchen sink thoroughly after each cooking session
    ✓ Do wipe your sink dry to prevent unsightly watermark stains after washing
    X Don’t use chloride-based detergents to wash the sink as they contain Sodium Hypochlorite, which can decolorize and cause unsightly surface staining

    X DON’T defrost food on the sink as it will intensify condensation beneath the sink
    X DON’T leave frying pans & steel wool (non-stainless steel type) overnight in the sink
    X DON’T use your sink as a chopping board
