Stainless steel sinks may look shiny and durable when they are new, but they are really quite delicate. If you are not careful, you may end up scratching your stainless steel sink. When this happens, you may be able to repair the damage by following a few easy steps.
Choose a commercial product suitable for use on stainless steel sinks such as Franke's Inox Cream or Bar Keepers Friend Liquid, and a fine 3M Scotch Brite pad. Cameo stainless steel cleaner is another product that can be used to remove scratches.
Clean and dry the sink before beginning your repair work. Rinse it well, then dry it with a soft, absorbent cloth or paper towels. This will give you a properly prepared surface in which to work and make it easier to see the scratch.
Make sure that you will have plenty of light in your work area. This will allow you to see the scratch as well as the grain of the sink, and to assess the progress of your work. If there are no suitable ceiling lights in the area, have an assistant shine a flashlight onto your work area.
Apply the cream or liquid you've chosen, and use the 3M pad to buff and blend the scratch. Always wipe with the grain or you might make the scratch more noticeable rather than removing it. Periodically stop, rinse and dry the work area, and check your work to ensure that the scratch is becoming less noticeable. You can stop once it blends in or disappears.
Thoroughly wash and dry the sink. Rinse it well, and rub it with a paper towel or clean, soft cloth as you spray the clean water. Dry it out to prevent the appearance of spots that are caused by the minerals and salts in tap water.
Very deep scratches may require a more aggressive method. According to the Dollar Stretcher website, you can get a rubbing compound and very fine-grit wet sandpaper from an automotive store. Try the rubbing compound first. If it does not remove the scratches, wet the sandpaper and work on the scratch gently and slowly until it can no longer be seen. Then finish it off with the rubbing compound.
According to askthebuilder.com, you should never clean your stainless steel sink with steel wool pads. Use nylon or a synthetic material and a cleaning solution that is approved for use with stainless steel sinks.
