Frequently Asked Questions

What is 304 Stainless Steel?
Nantucket Sinks are made from 304 stainless steel. To be classified as 304 stainless steel, it must contain 18% Chromium and no less than 8% nickel. What does the chromium and the nickel do you might ask? When chromium mixes with oxygen it forms a chromium oxide bond called the passive layer. When stainless scratches and it will, that layer will quickly bond back over the scratch preventing corrosion. The nickel used in conjunction with chromium adds an additional level of corrosion resistance.

What does the gauge of the stainless steel mean?
The gauge is the thickness of the stainless steel. Here is the confusing part. The higher the gauge, the thinner the steel. 16 gauge is thicker than 18 gauge. The majority of our product lineup is 16 and 18 gauge. What is the difference you might ask? Besides being thicker steel, our 16 gauge sinks offer increased durability and sound deadening properties as a result of its density.

How easy is it to clean my Nantucket stainless steel sink?
Very easy. The best way is with soap and water and to towel dry. For complete information check out our Care & Maintenance page.
NEVER USE BLEACH, CHEMICALS, OR ACIDIC CLEANERS. This may cause pitting or discoloration of your sink. Water with a high mineral content may cause spotting or discoloration.
NEVER USE STEEL WOOL. This may cause scratching or “Surface Rust”
Will my stainless steel sink scratch?
All stainless steel will scratch with use. Overtime those scratches will blend into the sink.

Does stainless steel stain?
As they say, stainless is called stain-less not stain proof. Any of the cleaners mentioned above may stain your stainless steel sink. In the event of staining or to restore the shiny luster of your Nantucket stainless steel sink, we recommend Bar Keepers Friend©. You will notice that your stainless steel sink has a grain. Make sure you always clean in the direction of the grain.

Is that rust in my stainless steel sink?
Because Nantucket Sinks are made from 304 Stainless Steel, the sink will not rust. If you do see small rust marks on your sink, it is what is called “Surface Rust”. Surface rust is caused by small iron particles bonding to the sink and rusting. This most often occurs immediately after installation when grinding or polishing tools were used on the solid surface countertop. Small metal splinters might have fallen from the underside of the countertop into the sink and causing the discoloration. Another cause can be from cast iron cookware or non stainless steel cooking utensils. Don’t Panic… it is easily removed with Bar Keepers Friend or a similar product of your choosing. Never use a rubber or plastic mat on the bottom of the sink. This can result in the iron particles bonding to the sink and causing discoloration. We recommend our sink grids to prevent excessive scratching and to promote proper drainage. Please contact one of our registered dealers for details.

What is on the underside of my stainless steel sink?
Nantucket Sinks are sprayed to insulate for water temperature retention. Rubber Pads are applied for sound deadening. People who are sensitive to the smell of rubber can remove the rubber pads by filling the sink with very hot water. Allow for the glue to become loose and peel the pad away from the steel. Be aware that this will result in your sink having a different sound quality when the water is flowing and will also diminish its temperature retention.

Care & Maintenance for Specialty Metals
Please be advised!  Read before use:
CARE & CLEANING Particular care is needed in the cleaning and maintenance of your item. Our items are considered to have a living finish. In other words, the finish will patina over time and develop its own unique character. This finish is not guaranteed for the life of the sink. The finish will however last a very long time with careful care and preventative maintenance. Your sink can and will be directly affected by environmental and personal maintenance factors. Factors include, water quality, air temperature and personal care products.

Preventative Maintenance
Before initial use, it is recommended that you use a superior quality carnauba paste wax to seal the finish before use. We also recommend repeating this process every 6 months in order to further protect the living finish.

To clean your product:
(Daily cleaning) Wash gently with a soft damp cloth. Use soap that is mild and free of anti-bacterial properties that may contain bleach. The original Dawn® soap is a good choice for its neutrality. Apply a small amount of soap to the damp cloth and gently clean the surface. Rinse thoroughly and hand dry. Never use steel wool or a scouring pad or sponge to clean the surface. The use of any cleaners or disinfectants other than mild soap and water will void the warranty.

Please Note! Personal care and everyday use products such as face cleansers, toothpaste, male grooming products, wine, fruit acid, and ketchup can and will alter the finish voiding the warranty. So please rinse thoroughly after exposure to the aforementioned products.

Fireclay Farmhouse/Apron Sinks
Due to the extra thickness at the bottom of our fireclay sinks, we recommend an extended flange for disposal drains/extended ferrule for standard drains shown here:  Extended ferrule or Disposal Drain.

Fireclay Care & Maintenance
Fireclay sinks have become increasingly popular due to their durable nature.  They do not rust or discolor, however it is important that they are properly cared for.  Below are several guidelines to follow when cleaning your fireclay sink.

Always rinse your sink thoroughly after every use and wipe down with a dry cloth to prevent water spotting.

For a more thorough cleaning, we recommend using a soft sponge or cloth and a mild abrasive. Daily cleaning with abrasives will not harm the surface of your fireclay sink.

Fireclay sinks are made using a durable glaze for years of performance. On the occasion that a metal pot or pan may leave a mark on the surface of the sink, we recommend using a mild abrasive cleaner such as Bar Keeper’s Friend.

To keep a nice luster on your sink, and easy to keep clean, apply a coat of Flitz Fixture Wax to the surface. Be sure it is clean and dry first. This is the same type wax you apply to your car. Make sure you rub the wax in until you have removed all of the residue. This will also alleviate water spots.

Fireclay resists scratches and chips better than any other ceramic material, however, in the rare occurrence that you may chip your sink it is important to fix it as soon as possible.  Repair kits are available at home improvement stores, and are very easy to use. It will come with everything you need to repair and seal the chip.
