Use and Care Manual
The General Care and Cleaning of Any Kitchen Sink
Kitchen sinks are available in stainless steel, TruGranite, and copper. For general maintenance all can be regularly 
cleaned with a mild detergent, warm water and a soft cloth. Wiping down and drying any sink after each use is the best 
protection against hard water creating blemishes which may become difcult to eliminate. For a thorough cleaning after 
extended use, or to remove stubborn stains, each material requires its own deep cleaning solutions.

PATINA 
Copper changes and evolves with time as it reacts 
with the environment. While a new copper sink will 
add beauty and style to any decor, the natural 
oxidization process, or patina, requires some 
maintenance. 
SANITIZATION 
The best way to clean a copper sink is with a solu-
tion of mild soap and water, followed by a wipe-down 
with a soft cloth. Avoid using copper cleaners on your 
sink as they can be abrasive; scratching the surface 
and distorting the patina. 
WATER SPOTS 
If you have hard water, you will want to keep your 
copper sink clean and dry to avoid water spots. 
Clean it regularly with a mild, non-abrasive cleanser 
and wipe it dry with a soft cloth after each use.

POLISHING AND WAXING 
To help protect your copper sink from hard water 
mineral damage, a wax such as Renaissance Wax
® 
can be applied periodically. This will help maintain 
the luster of your sink, however, the use of wax will 
temporarily stop the development of the natural 
patina. 
We do not recommend polishing a copper sink 
with an abrasive substance or material, as vigorous 
scrubbing can strip off the natural patina.
ACIDIC FOODS 
DO NOT leave acidic foods such as oranges, lem-
ons, vinegar, pineapple or tomatoes sitting in a 
copper sink. Contact with acidic foods could cause 
shiny spots or discoloration in the sink. Simply clean 
the area with soap and water if contact occurs. Over 
time, the patina will recover and the spot will blend 
into the sink. To avoid this reaction, run water in the 
sink while working with acid-based foods and clean 
immediately afterward.
