Kohler product cannot rust on its own. Rust is caused by a metallic particulate which has oxidized on the surface of a product and turned it to rust. When rust occurs on a product, it resides on the top surface. Glass, enameled cast iron, vitreous china, stainless steel, and Vikrell cannot rust on its own. Rust is not the result of a manufacturing process, nor is it considered a defect in the product.
To reduce the chance of rust occurring, keep the following in mind:
- Don't leave dish rags or other cleaning utensil on the counter top or in the sink basin.
- Rubber mats left in the sink will allow soap and hard water deposits to form in the grain of the sink.
- The use of abrasive pads, even sparingly, will allow rust to get into the grain of a sink.
- Hard water in the house may also account for rust stains.
When rust does appear, it is typically only surface rust and can be removed easily with the right cleaners. Do not use steel wool, wire brushes or abrasive sponge pads. Use on non-scratch cleaning pads.
See the Care & Cleaning site on us.kohler.com for more information about the products to use to care for your Kohler product.
Rust Inside the Sink: If rust appears on the inside of your sink it is likely the result of the chemicals being used in, or around, the sink. Do not use cleaners with bleach to clean counter tops adjacent to the sink: The overspray can land on the sink and cause rusting. Thoroughly rinse down the sink after using the counter top cleaner.
Rust on Underside of Sink: If rust appears on the underside of the sink it is likely due to the contents of the cabinet the sink sits on top of. Fumes from many household chemicals can rust a stainless steel sink. Do not store open containers of cleaners or chemicals such as bleach, acids, salt, lye, toilet-bowl cleaner, drain cleaner, or hard water stain removal products under your sink.
