How to Inspect a Stainless Steel Sink

 
Stainless steel sinks are one of the most popular types of sink, thanks to their affordability, durability, and low-maintenance. They are also resistant to heat, stains, corrosion, and bacteria. However, not all stainless steel sinks are created equal. There are different grades, gauges, series, and finishes of stainless steel that affect the quality and performance of the sink. Moreover, stainless steel sinks can also get scratched, dented, or water-spotted over time if not cleaned properly.
 
If you are looking for a new stainless steel sink or want to check the condition of your existing one, you need to know how to inspect it properly. In this article, we will guide you through the steps and methods of inspecting a stainless steel sink, as well as some tips on how to maintain it.
 
What to Look for in a Stainless Steel Sink
 
Before you inspect a stainless steel sink, you need to know what to look for and what to avoid. Here are some of the main factors that determine the quality and durability of a stainless steel sink:
 
Grade: The grade of stainless steel indicates the percentage of chromium and nickel in the alloy. Chromium and nickel are the elements that give stainless steel its corrosion and stain resistance. The higher the grade numbers, the better the quality of the steel. Look for 300 series stainless steel, which is the most widely used and has 18% chromium and 8% nickel. Within the 300 series, 304 is the most common grade, also known as 18/8 stainless steel. Another high-quality grade is 316, also known as surgical grade or marine grade, which has 18% chromium and 10% nickel and is more resistant to saltwater and acids.
 
Gauge: The gauge of stainless steel refers to the thickness of the metal sheet. The lower the gauge number, the thicker the steel. Thicker steel is more durable and less prone to denting and damage. It also produces less noise when washing dishes or running water. Most stainless steel sinks use 16 to 22 gauge steel. For comparison, 16-gauge steel is 0.0625 inches thick, while 22-gauge steel is 0.0313 inches thick - less than half! A sink with a lower gauge is more expensive but has a much longer life expectancy. Look for 16- or 18-gauge sinks for the best quality.
 
Series: The series of stainless steel is related to its grade. It indicates the type of alloy used and its properties. For example, 304 stainless steel belongs to the austenitic series, which means it has a high amount of chromium and nickel and is non-magnetic. Another common series is ferritic, which has less nickel and is magnetic. A good way to check the series of a stainless steel sink is to use a magnet. If it sticks, it is not 300 series.
 
Finish: The finish of stainless steel refers to the surface appearance and texture of the metal. There are different types of finishes that can affect the look and feel of the sink, as well as its resistance to scratches and fingerprints. Some of the common finishes are:
 
Brushed: This finish has fine lines or grooves on the surface that create a matte or satin look. It is easy to clean and hides scratches well.
 
Polished: This finish has a smooth and shiny surface that reflects light. It is more attractive but also more prone to fingerprints and water spots.
 
Hammered: This finish has small indentations on the surface that create a rustic or antique look. It adds character but also makes cleaning more difficult.
 
Embossed: This finish has patterns or designs on the surface that create a decorative or artistic look. It can enhance the style but also increase the cost.
 
How to Inspect a Stainless Steel Sink
 
Now that you know what to look for in a stainless steel sink, you can proceed to inspect it using various methods. Here are some of the steps you can follow:
 
Look for the model number or serial number: If your sink has not become too battered or dulled, chances are the model number or serial number is still readable. You can find it on the underside or backside of the sink, usually stamped or engraved on a metal plate or sticker. The model number or serial number can tell you the manufacturer, brand, style, size, grade, gauge, series, and finish of your sink. You can use this information to compare with other sinks or check online for reviews and ratings.
 
Compare with another stainless steel appliance: If you have another stainless steel appliance in your kitchen, such as a refrigerator or oven, you can compare it with your sink to see if they have the same grade and series. For example, if your appliance is 304 stainless steel and your sink is magnetic, then your sink is not 304 stainless steel. You can also compare the shine and color of the steel to see if they match.
 
Look at the shine: The shine of the stainless steel can indicate its quality and condition. A high-quality stainless steel sink should have a bright and even shine that reflects light well. A dull or uneven shine can mean that the steel is low-quality, scratched, stained, or corroded. You can use a flashlight or a mirror to check the shine of your sink from different angles and spots.
 
Check for sound: The sound of the stainless steel can indicate its thickness and durability. A thick and sturdy stainless steel sink should produce a low and muffled sound when you tap or knock on it. A thin and flimsy stainless steel sink should produce a high and tinny sound when you tap or knock on it. You can use a spoon or a coin to check the sound of your sink from different areas and depths.
 
Scratch with a key: The scratch resistance of the stainless steel can indicate its hardness and finish. A hard and brushed stainless steel sink should resist scratches well and hide them easily. A soft and polished stainless steel sink should scratch easily and show them clearly. You can use a key or a knife to lightly scratch your sink in an inconspicuous spot, such as the drain hole or the back rim. If the scratch is deep or visible, then your sink is not very scratch-resistant.
 
Check with a magnet (least effective): The magnetism of the stainless steel can indicate its series and grade. A non-magnetic stainless steel sink should belong to the 300 series and have a high amount of chromium and nickel. A magnetic stainless steel sink should belong to the ferritic series and have a low amount of nickel. However, this method is not very reliable, as some 300 series stainless steel can become slightly magnetic due to cold working or welding. Moreover, some non-stainless steel sinks can be non-magnetic as well, such as aluminum or copper sinks. Therefore, you should use this method as a last resort or in combination with other methods.
 
How to Maintain a Stainless Steel Sink
 
After you inspect your stainless steel sink, you may want to know how to keep it in good condition and prevent it from getting damaged or stained. Here are some tips on how to maintain your stainless steel sink:
 
Clean regularly: You should clean your stainless steel sink after each use or at least once a day to remove any food particles, grease, soap residue, or water spots that may accumulate on the surface. You can use dishwashing liquid, baking soda, vinegar, or a mild cleaner designed for stainless steel. Avoid using abrasive cleaners, scouring pads, steel wool, or bleach that may scratch or discolor the metal.
 
Dry thoroughly: You should dry your stainless steel sink after each cleaning or rinsing to prevent water spots from forming due to minerals in hard water. You can use a microfiber cloth, paper towel, or a soft cloth to wipe down the surface until it is completely dry.
 
Polish occasionally: You can polish your stainless steel sink once in a while to restore its shine and remove any minor scratches or stains that may have formed over time. You can use olive oil, baby oil, lemon oil, or a commercial polish designed for stainless steel. Apply a small amount of oil or polish on a soft cloth and rub it on the surface in circular motions. Then wipe off any excess oil or polish with another clean cloth.
 
Protect from damage: You can protect your stainless steel sink from damage by using some accessories or precautions that can prevent scratches, dents, or corrosion. For example, you can use a sink grid, mat, or rack to cushion the bottom of the sink from pots, pans, knives, or utensils that may scratch or dent it. You can also use a cutting board to chop food instead of using the sink directly. Moreover, you can avoid leaving acidic foods, such as citrus fruits, vinegar, or tomatoes, on the surface for too long as they may corrode the metal.
