Suggestions for the Care & Cleaning of Your Stainless Steel Sink
Your Valore` sink is made from Quality 18/10 stainless steel and will give you a lifetime of service with proper care and maintenance. Even the highest quality stainless steel will not last if mistreated.
What is stainless steel?
Stainless steels are a family of steels that are resistant to corrosion (rusting) and elevated temperature. They must contain at least 10.5 % chromium. The chromium reacts with the oxygen in the air to form an invisible, protective chrome-oxide surface layer. This layer helps to prevent "staining (rusting) of the surface. This does not mean that stainless steel will never rust. There are many different stainless steels with unique chemical compositions. These chemistry differences influence strength, corrosion resistance, and cost. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum improve the corrosion resistance and make them easier to fabricate. The most commonly used stainless steel for sinks, flatware, appliances, and other consumer products is Type 304 but other less expensive and less corrosion resistant stainless steels are sometimes used and the consumer should not assume that all stainless steel products will provide equivalent performance.
I notice my Stainless Item says 18/8 or 18/10. What does this mean? The first number is the amount of chromium that is contained in the stainless i.e. 18 is 18% chromium. The second number is the amount of nickel i.e. 8 stands for 8% nickel. So 18/8/means that this stainless steel contains 18% chromium and 8% nickel. This is a common name for Type 304. 18/10 is 18% chromium and 10% nickel. The higher the numbers the more corrosion resistant the material.
Stainless Steel Cleaning Tips
Stainless Steel
Is widely used for catering and domestic kitchen equipment because of its ability to resist corrosion and its ease of cleaning. In fact, stainless steel ranks alongside glass and new china in terms of "ease of cleaning" and in removal of bacteria from the surface. As a result of these virtues, the metal is often taken for granted and it is assumed that no problems will arise during its usage. However, some care is required to ensure that the. Stainless steel can live up to its reputation.
Surface Scratching
Although stainless steel is a relatively hard material, it is possible to introduce surface scuffs and scratches when harder objects are drawn across the metal surface. Examples of harder materials are knife blades, cast iron saucepans, ceramic pots and mugs (particularly the unglazed area on the base) and certain abrasives/scouring materials. Scratching will be most noticeable on the drainer area of the sink where hard objects are likely to be placed during normal household use. These scratches and marks are usually only superficial and can sometimes be removed depending on severity with a proprietary stainless steel cleaner/polish such as Polaris stainless and copper restorer generally available from the local supermarket. like any metallic surface, your stainless steel sink will scratch, these are usual scratches and over time will blend into the overall finish of your sink.
Corrosion The two most common types of corrosion that may be encountered, particularly on stainless steel sinks, are rust marks and pitting of the surface. 1: Rust Marks. When this type of staining occurs, it is unlikely that the marks are caused by the rusting of the stainless steel itself ( The material used is a high quality 18/10 chrome nickel steel which is metallurgical incapable of rusting or corroding in normal household conditions, similar marks can be found with both porcelain and composite sinks). The rust marks are more likely to be the result of small particles of "ordinary steel" which have become attached to the surface, these have subsequently rusted in the damp environment of the sink. The most common source of such particles is from "wire wool" scouring pads, or wire wool used by the plumber during the installation of the sink. Contamination may also occur from carbon steel utensils and old cast iron water supply pipes. These brown marks are only superficial stains, which will not harm the sink; they should be removed using a soft damp cloth and a multi purpose cream cleanser (such as Jif). Occasionally, it may be necessary to resort, to a proprietary stainless steel cleanser, to return the surface of the sink to its original condition. To avoid reoccurrence of any "rust-staining" it is essential that the source of the contamination is eliminated. In cases where contact cannot be avoided, it is even more important that the sink is given a thorough cleaning treatment after use.
2: Pitting. Another form of corrosion, which occasionally occurs in stainless steel sink bowls, is pitting of the surface: in extreme cases this may lead to perforation of the metal. The reason for this corrosive attack can usually be attributed to certain household products, for example:-
Bleaches Most common domestic bleaches/sterilizing solutions contain chlorine in the form of sodium hypochlorite. They should always be used to the strengths prescribed by the manufacturer and should be thoroughly rinsed off with clean water immediately after use. Any cleaning agents containing hypochlorites are unsuitable for long term contact with stainless steel and even when used in the highly diluted form, they can give pitting under certain conditions. For this reason it is not advisable to use a stainless steel sink for soaking fabrics in these solutions, especially over long periods of time (e.g. overnight).
Silver Dip Cleaners.These are particularly harmful as they contain strong acids which can very quickly cause discoloration and pitting. If this type of cleaner comes into contact with the surface of the sink, it should be thoroughly rinsed off with clean water.
Foodstuffs.In general, stainless steel is fully resistant to all foodstuffs in common use. Only in isolated cases, such as when concentrated salt and vinegar mixtures are allowed to dry and remain in contact with the steel for a long period, can any surface marking result. highly acidic foods such as tomatoes, pickles or lemon should not be allowed to sit on the sink surface, It is always good practice to wash down the stainless steel surface after food preparation.
Acids.Strong acids such as sulphuric and hydrochloric are very corrosive and should not be allowed to come into contact with stainless steel catering 'equipment. If equipment is used for purposes other then foodstuffs e.g. photographic processing, it is essential that all traces of the solutions should be washed off immediately.
Water Quality.
The quality of your water can affect your sinks appearance, if your water has a high Iron content, a brown surface can form on the sink giving the appearance of rust, additionally, in areas with a high concentration of minerals, or with over-softened water, a white film may develop on the surface of the sink, to combat these problems, we suggest that the sink be towel dried after use, Once a week thoroughly clean the sink.
Day to Day Care.To maintain the original appearance of the sink, a regular cleaning routine should be carried out using the following guidelines:-
1: After use, wipe the item with a soft, damp, soapy cloth and rinse with clean water, preferably - warm/hot water. This should remove most substances encountered within the kitchen environment.
2: For more tenacious deposits, including oil, grease and waterborne deposits, use a multipurpose cleanser (such as Jif or Polaris) and apply with a soft damp cloth. This should be followed by rinsing with fresh water, as above. Note Jif and Polaris are abrasives and should not be used too aggressively.
3: Harsh abrasives and scouring materials should not be used for cleaning stainless steel as they will leave scratch marks in the surface and damage the appearance of the sink. Likewise, do not use wire brushes, scrapers or contaminated scouring pads.
4: If the sink has a directional polished grain, any cleaning with abrasives should be carried out along this grain and not across it.
5: After use, always remove wet cleaning-aids (such as cloths, pads, containers) from the surface, to avoid formation of water marks/stains.
6: If required, dry the sink after use with a soft dry cloth or towel.
