Franke stainless steel sinks are made from premium quality chrome nickel steel giving it stunning beauty while making it highly resistant to staining, rust and corrosion - plus it won't chip, craze, flake or break.
This high quality Franke sink is made from a heavy gauge, type 304 (18/10), surgical grade stainless steel for maximum durability. It is composed of 18% chromium (for shine) and 10% nickel (for rust resistance). Stainless steel is an extremely durable surface; it can, however, be scratched or scuffed. When scuffing does occur, please remember that this is normal and the effect will become uniform with age. The high quality stainless steel does not lose its attractive shine.
Regular cleaning is important to maintain the appearance of your Franke 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.
The surface scratches which appear on stainless steel sinks rarely have any appreciable depth and will become less noticeable with age. A stainless steel sink will develop a patina with time and will look better a year after installation than during the first few months of use due to the fact that the scratching will have evened out. All sinks manufactured in stainless steel perform in exactly the same way in this respect be they Franke’s manufacture or by a competitor.
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 (such as Bar Keepers Friend). Steel wool pads leave tiny particles that will develop into rust spots. Stainless steel is, by itself, metallurgically incapable of rusting. Never use steel wool to clean your stainless steel sink. Persistent stains, including rust, can be removed with a variety of mild non-abrasive stainless steel cleaners such as Franke’s Inox cream, Autosol Shine, and others. Always rinse thoroughly after using any cleaner.
Scratches can be blended in using the fine (white) 3M Scotch Brite pad and Inox cream, if desired. Always wipe with the grain, rinse thoroughly and dry when finished.
- 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 citric fruit juices, salt, vinegar, mustard, pickles, and mayonnaise.
- 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
- Steel wool pads are not recommended for cleaning stainless steel sinks.
