Enameled Cast Iron Sink Care

Restoring Luster to an Enameled Sink

Enameled surfaces can lose the original luster with improper care and cleaning. Abrasive cleaners are not recommended.
For detailed cleaning information and products to consider, visit kohler.com/clean.

Rubber dish mats are not recommended in KOHLER® sinks.
Bacteria can grow under the mats and permanently discolor the enamel.
Discoloration from rubber mats is not covered under the manufacturer's defect warranty.

Black spots in the finish of enameled products are referred to as "carbon spots."
The carbon spots are the result of dust particles that get burned into the finish during the enamel firing process.
Carbons spots are a normal part of the manufacturing process. Typically, the spots are small and minimal, however the product should be inspected prior to installation for large or clustered carbon spots. If you have concerns about the size or quantity of the carbon spots, contact 800-4KOHLER for more information.

Pot marks are caused by metal objects (most commonly aluminum cookware) striking the enameled surface and are not a manufacturing defect.
Pots, pans, and utensils may leave the metal marks on sink surfaces because the thick layer of fire-polished enameled is harder than cookware.
The pot marks look like scratches, but they do not penetrate the enameled surface.
To clean, apply a small amount of KOHLER Cast Iron Cleaner (part #1012525) to the marks. Use a soft cloth or cork to gently rub the marks away.
