Care of Your Seima Stainless Steel Sink

Stainless steel is a very durable surface, however it can be scratched or scuffed. When scuffing occurs, please remember that this is normal and the effect will become uniform over time.sink

Most good quality sinks are manufactured from heavy gauge type 304 stainless steel for maximum durability (type 304 is surgical grade stainless steel), and Seima’s stainless steel sinks are no exception.

The following guide will ensure that your continues to shine for many years to come.

Recommended Daily Care

Regular cleaning is important to maintain the appearance of your sink.

Wipe with a soft, soapy cloth, rinse and dry after every use. Drying is very important to eliminate any film build-up that may develop from hard water deposits.

Tough Stains and Rust

Most stains are a result of water-borne minerals. Such stains are often seen as a “rainbow” effect and can generally be avoided with the daily care recommendations above. Rust stains are a result of iron particles from an outside source (i.e., water, cookware, etc.) and can be removed with cleaners containing oxalic acid.

Steel wool pads leave tiny particles that will develop into rust spots. Stainless steel by itself will not rust. Persistent stains, including rust, can be removed with a variety of mild, non-abrasive stainless steel cleaners. Always rinse thoroughly after using any cleaner.

For heavier soiling or light staining, apply the mildest household abrasive cleaner or a paste made from bicarbonate of soda, or a stainless steel sink cleaner. Using a soft cloth, fine nylon scouring pad or soft bristle brush, rub the surface as softly as possible, using long even strokes in the direction of the polished finish (remember to wear gloves). Avoid using a circular motion. Rinse well and wash as per routine cleaning.

Scratches can be blended in using a “fine” 3M Scotch Brite pad and cleaning paste, if desired. Always wipe with the grain, rinse thoroughly and dry when finished.

What To Avoid to Keep Your Sink Looking Good

  • Bleaches containing hypochlorite will attack stainless steel and cause pitting and staining.
  • Silver dip cleaners contain acids which attack stainless steel and leave a permanent stain.
  • Certain foods, when left for prolonged periods, can cause pitting and corrosion. Examples are salt, vinegar, mustard, pickles, and mayonnaise.
  • Fruits or juices on the sink; wipe them up immediately as they contain citric acids which over time can etch the surface.
  • Strong acids can damage stainless steel (i.e. photographic developing liquids or denture cleanser). If they come in contact with the sink, they should be washed away immediately with clean water.
  • Don’t allow liquid soap or cleanser to sit for a prolonged period or to dry on the surface of the sink as most brands contain chemicals that can affect the shine of the sink.
  • Don’t use a steel wool pad to clean your sink. If a more abrasive product is needed, use a liquid cleanser being sure to rub in the direction of the sink grain lines. (Steel wood pads will leave small particles of steel embedded in the surface of the sink that will rust and give the appearance that the sink itself is rusting.)
  • Don’t leave bars of soap, wet sponges or cleaning pads on the tap landing as these will dull and possibly pit the surface of the finish over time.
