How To Repair Rusted Porcelain Sinks

You can repair rusted porcelain sinks by trying out some of these effective cleaning methods. Rust can be difficult to remove without the proper cleaners and tools. Rust stains are usually the result of a leaking faucet, so make sure you also repair the leak after removing the stains.  Luckily porcelain is an easy surface to clean, so removing rust should be easy.

In order to repair rusted porcelain sinks you will need these supplies

  • An abrasive cleaner like Comet or Barkeeper’s Friend
  • A scouring pad
  • Lime Away or other product that removes hard water
  • A toothbrush
  • A pumice stone (found in the beauty aisle at grocery stores)


  1. First clean the sink well using an abrasive product like Comet or Barkeeper’s friend. You will want to remove all of the soap scum and other dirt before attempting to remove rust. 
  2. Use a product that removes hard water stains like Lime Away. Clean out all of the nooks and crannies with a tooth brush.  This will really improve the appearance of your sink.  What’s the point in removing the rust if your sink still looks grimy?
  3. Wet the pumice stone. Apply light pressure to the stained areas. Be careful not to scrub too hard or you will scratch the porcelain surface. 
  4. Throw the rust debris into the garbage. This material could potentially clog your drain. 
  5. Keep the pumice stone wet and occasionally remove the rust from the pumice “pores."
  6. Rinse well and enjoy your new sink.
