Oliveri sinks are manufactured from genuine 18/10, 304 grade stainless steel, for optimum hygiene and durability. However, no stainless steel sink was ever designed to do battle against hardened metal utensils or food processor blades, etc, without incurring at least a few scratches.
The best prevention against scratching is to exercise a little extra care, or even to use one of Oliveri’s bowl protectors or dish baskets when washing cutlery and the like.
To maintain the shine on your Oliveri sink, regular maintenance is recommended with any of the easy to obtain, non-abrasive stainless steel cleaners or metal polishes.
The Dos and Don’ts of Cleaning Your Sink
Do
Rinse Sink Thoroughly
Rinse your sink thoroughly after each use. Stainless steel looks best if it’s cleaned regularly with plenty of water.
Towel Dry Your Sink
Towel dry your sink with a dry, soft, absorbent cloth after each use. This prevents mineral deposits in the water from building up on the surface of the sink.
Clean Sink Once a Week
Clean the sink once a week, being sure to rub in the direction of the satin finish lines using an Oliveri recommended cleanser.
Use Glass Cleaner for Added Shine
Wiping over your sink with a glass cleaner is a great way to make your sink shine.
Use Stainless Steel Cleaners
Stainless steel polishing creams can make existing scratches less noticeable.
Don’t
Leave Juices on The Sink
Don’t leave fruits or juices on the sink; wipe them up immediately as they contain citric acids which over time can etch the surface.
Leave Chemicals on the Surface
Don’t leave chorine/chloride chemicals on stainless steel surfaces as this could damage 
the surface of the sink.
Leave Sponges on the Sink
Don’t leave bars of soap, wet sponges or cleaning pads on the faucet ledge. Over time, these items will dull and possibly pit the surface of the finish.
Store Chemicals Beneath the Sink
Don’t keep harsh (acids, chlorine, bleaches, etc.) chemicals under sink / laundry tub.
