When it comes to maintenance, the best thing you can do is to be consistent in your cleaning.· It is preferable to clean a little on a frequent basis than a heavy duty cleaning once in a while.
You should make sure that the sink is always clean and dry when not in use. This is the best method of preventative maintenance. Keep the sink water spot free and shiny by rinsing and towel drying after every use.
Keep the single clog free to prevent standing water which can lead to mineral deposit build up. If a mineral build up should occur, use a mixture of vinegar and hot water to remove the deposit.
To clean your sink, use a non abrasive cleaning cloth combined with a mild cleaning procedure. Use a soft cloth and liquid detergent on a mirror finish deck. For tougher stains use a mild abrasive cleaner like Ajax or Comet.
Follow the direction of the grain when cleaning or scrubbing away stains, scrubbing against the grain will show as a scratch.
Do not leave soaps and other cleaners in your sink overnight. Do not use solutions with bleach. All of these contain chemicals that may damage your sink if left on the surface.
Do not use steel wool on your sink. If aggressive cleaning is needed, use a Scotch-Brite pad and rub in the direction of the satin finish lines.
Do not leave bars of soap, wet sponges or cleaning pads on the faucet ledge. These items over time will dull and possibly pit the surface of your sink.
Do not leave salt, vinegar, citric fruit juices, mustard or pickles on the sink; wipe them up immediately as they contain citric acids which over time can etch the surface.
Do not leave any steel or cast iron cookware in the sink for a long period of time. This may also leave iron particles that will corrode the sink.
