Below are some frequently asked questions with answers.

Why use stainless steel?

Stainless steel is the most durable material for washrooms. Compared to other common used materials like ceramic or composite materials, stainless steel is extremely resistant against vandalism, heat - such as marks from cigarettes, commonly used chemicals like acids and is impact resistant. The material is colour-neutral and combines well with all other materials and colours. Stainless steel is hygienic and easy to clean. Additionally stainless steel is 100% recyclable and therefore very environmentally friendly.

Can you offer tips to insure long-lasting beauty for my stainless steel sink?

Do routine cleaning using soap, warm water and a sponge. Rinse thoroughly and wipe dry. To remove stubborn stains try Comet, Ajax, BonAmi, BarKeeper's Friend or similar products. Always rub in the direction of the grain, rinse thoroughly, and wipe dry. To maintain luster: use a small amount of mineral oil on a soft cloth. Apply evenly to the entire surface of sink and buff to a shiny finish.

Is there anything I should avoid while cleaning my sink?

Do not ever use steel wool, scouring pads, steel brushes, etc. Their particles may become embedded in the sink surface and cause a rusty discoloration.

I have rust in my sink - how can this be?!

Stainless steel is a wonderful material that does not rust. However, if given the opportunity, iron particles that do rust will bond to its surface - from metal cooking implements for instance. To remove this surface corrosion, place a small amount of Autosol® on a damp or dry cloth. Rub in the direction of the grain on the bottom or sides of the bowl. You may also use Scotch-Brite® on the bottom or sides of the bowl but NOT on the mirrored surface. If the mirrored finish has dulled, use a metal polish such as Peek® to restore its lustre. Please do not use a silver dip cleaner. Thoroughly rinse and towel dry. Sink tip: Regularly rinse and towel dry your sink after use to keep its surface exposed to oxygen. (It is the oxygen that reacts with chromium in the steel to form a strong, highly protective chrome oxide film on the surface. It is this film that makes stainless resistant to corrosion and gives it a remarkably long life)

Which bowl configuration is better - double or combination?

Bowl configuration really is a personal preference. If you tend to use a lot of large platters, roasters or pots, a combination bowl sink might be a good choice. An equal sized double bowl is a good wash and rinse model.

Why is water spotting my sink?

If water is left standing anywhere on your stainless steel sink, it will evaporate and leave a film (spots) on the surface of the steel. This film can be removed with regular dish soap and water and a soft cloth. For removing heavier residue, you may use a mild solution of vinegar and water (20 % vinegar, 80 % water). Rinse off with clean, cold water after cleaning to remove the residue of cleaning materials and towel dry. TIP: Regularly rinse and towel dry your sink after use to keep its surface exposed to oxygen. (Oxygen reacts with chromium in the steel to form a strong, highly protective chrome oxide film on the surface of your sink. It is this film that makes stainless resistant to corrosion and gives it a remarkably long life.)

Will my new stainless steel sink scratch?

As with most things, your stainless steel sink WILL scratch with use. However, over time as the sink ages, scratches will become less apparent and in fact blend into the surface.

Will stainless steel sinks withstand extreme temperature?

Stainless steel stands up to high hot or cold temperatures, along with sudden temperature changes. That means you can drain hot boiling pasta in your sink, followed with a rinse of ice cold water, without causing any damage to your sink's surface.

What's the difference between an undermount and topmount (or ‘self-rimming') sink?

A topmount sink has a lip that folds over the countertop and is therefore resting on top of the countertop cutout. Fasteners securely mount an undermount sink underneath the countertop so that a polished edge of granite, marble, etc. is exposed above the sink. An undermount sink cutout requires more polishing and installation labor than a topmount sink cutout and is therefore a more expensive option.

How do I punch extra holes in my drop-in stainless steel sink?

Stainless steel sinks should be punched prior to purchase. Order the sink requesting the extra hole, if that is an option. Drilling holes may dent a stainless steel sink and cause a brown discoloration around the hole due to heat caused by friction. 

What should I look for in the finish of the steel?

Look for a rich, deep, satin-smooth finish rather than a surface gloss. The luster comes from machine and hand-finishing operations, which enable the sink to keep its beauty for years - without cracks, chips, rust or stains. Many feel that the look actually improves with age, taking on a soft patina glow. Most commercial sinks come with a No.4 satin finish.

What is the purpose of the undercoating on my sink?

The undercoating on your sink absorbs sound, protects against condensation and helps maintain sink water temperature.

Are there different types of stainless steel for sinks?

Yes. In fact, some stainless steel sinks look bright and shiny at first, but rust or corrode in time. All stainless steel sinks are not equal in quality and material content. Look for the best combination of chromium and nickel for superior corrosion resistance and durability. Very. The thicker the steel, the less susceptible it is to denting, bowing and noise transmission from pots and pans hitting the metal surface.

What does the gauge of the stainless steel mean?

The gauge is the thickness of the stainless steel. An easy rule of thumb is, the lower the number of the gauge, the thicker and better the stainless steel. Therefore, 18 gauge is better than 20 gauge.

PRODUCT CERTIFICATES
Why Do You Certify Your Products?

Franke Commercial Systems strongly believes in product certification. We strive to have our products designed and certified to meet all applicable standards.

Which soaps can be used?

Because of the large amount of available soaps we are not able to give suggestions for products to be used. Please check the ingredients very carefully. Liquids in contact with stainless steel must not be strong acids or salts like chloride, bromide, iodine and similar chemicals. These chemicals in contact with stainless steel can cause corrosion. If your soap dispenser is equipped with a tank cover make sure that it is in place. Evaporating of ingredients can cause aggressive gases which also can be very corrosive. Disinfectants act very aggressively on the seals of the soap dispensers.

Can disinfectants be used in soap dispensers?

Because of the large amount of available disinfectants we are not able to give suggestions for products to be used. Please check the ingredients very carefully. Liquids in contact with stainless steel must not be strong acids or salts like chloride, bromide, iodine and similar chemicals. These chemicals in contact with stainless steel can cause corrosion. If your soap dispenser is equipped with a tank cover make sure that it is in place. Evaporating of ingredients can cause aggressive gases which also can be very corrosive. Disinfectants act very aggressively on the seals of the soap dispensers. If the pump gets damaged by the use of aggressive liquids, a replacement pump can be ordered from your local Franke partner.

Which paper fits into my dispenser?

Basically the Franke paper towel dispenser are designed in a way, that the maximum possible amount of paper types can be used. Please note the maximum dimensions that fit into your dispenser. Commonly known paper product manufacturers offer a huge amount of different paper types of different quality (1 - 3 layer) and sizes.

Which batteries are used?

Franke recommends the use of high quality brand name batteries of the following types: Standard D 1.5 V batteries for paper towel dispensers, Alkaline AA 1.5 V batteries for soap dispensers, lithium CRP2 6 V batteries for taps.

How long is the lifespan of batteries with single products?

The lifespan of batteries is dependant on a lot of different factors. Most important is the quality of the batteries used. Tests by Franke have showed that there is a dramatic difference between brand name products and un-branded products. Brand name products had up to ten times lifespan. Another factor is the amount of usage. Less used batteries have a smaller lifespan, because of the self-discharge. Large temperature-differences and low temperatures also have a negative effect on the lifespan of the battery.
