SINDA Maintenance Information

Maintenance Information for SINDA Copper Range Hoods & Copper Sinks:

The copper used for your sink and range hood is pure Virgin Copper, and has been treated with a clear lacquer sealant, which provides extra protection to the patina and to the copper surface. Yet it is important to remember that even the strongest lacquer cannot take the place of responsible care and
maintenance. Kindly note the maintenance information below to properly care for your copper product.


Caring for copper products is easy, as they require very little maintenance.

● For regular, simple cleaning, use mild NON-ACIDIC liquid detergent or soap and water and a very soft non-abrasive cotton cloth; other cleaners are not necessary. We recommend a PH-balanced liquid dishsoap such as Ivory, avoiding harsh detergents such as Dawn/Palmolive etc. For occasional deeper
disinfecting, a non-abrasive, non-corrosive cleaner may be used, such as diluted Simple Green.


● Keep your sink and drain clean and dry by wiping it down and removing all excess water each time it is used with a soft cloth.

● Do not use copper polish/cleaners, abrasive materials, acidic or abrasive cleaners (such as Comet/Soft Scrub) or harsh chemicals such as acetone – these will compromise the integrity of the Lacquer Finish and can ruin the surface of the sink.

● As copper is a natural metal, it will naturally patina slightly with use, over time, and the copper sink will develop a warmer, richer patina. The sinks will not turn green as the lacquer is protective.

● Although the copper is heavy, strong 16 gauge copper, as copper is still a rather soft metal and dent easily, to further protect the bottom, apron front, and rims of Copper Kitchen Sinks, rubber mats may be used (in the bottom of the sink bowls and over the rims) while cleaning dishes. Remove the rubber mats
as soon as possible and do not leave them in the sink.

● Hot pans taken directly from a stove/oven should not be placed in copper sinks until cooled.

● The copper sinks need to be waxed approximately every 3-6 months depending on the frequency of use.
Beeswax or Honey Wax products such as Flitz Fixture and Faucet Wax (available online at Flitz.com), are recommended. Apply wax lotion with a soft, clean cloth and buff with a clean, soft, non-abrasive cloth, referring to wax manufacturer’s instructions.

Note: Wax may be applied OVER clean, dry Lacquer finishes regularly to give sinks a rich look and to protect and extend the life of the lacquer sealant indefinitely.

● SCRATCHES: A surface scratch that penetrates the lacquer can cause the underlying copper to patina. A light application of KRYLON Clear Sealer can be used over a cleaned, dry sink to re-seal the scratched surface. Please refer to our Terms or Conditions for further warranty information regarding finishes.

● INSTALLATION: Cuts made for copper products in countertops, cabinets, tiles, etc. should NOT be made until the copper product has been received and properly measured on-site. Installation should be done with a silicone sealant and not with epoxy sealants, and no Plumber’s Putty should be used with Drains. Installers must not use any tape adhered on the copper, as it will damage the lacquer.

● As all copper products are individually handcrafted and made-to-order, minor variations in patinas, textures, and dimensions of your copper product should be anticipated.
