However, if you’re going to clean them using harsh cleaning materials such as steel wool, wire brushes, or the sponge’s abrasive side, your cast iron sink will likely get scratches. 

This is why it’s never advisable to clean cast iron sinks with these harsh cleaning objects, or else, the scratches will expose the base cast iron, making it prone to rusting. 

Even though the enamel coating can be repaired, the sink’s overall appearance might not look elegant as before.

Are Cast Iron Sinks Hard To Clean?

  2. Let the sink completely dry. You can just leave it as it is since it won’t leave any ugly watermarks. However, you can also dry it by wiping the sink with a soft cloth or microfiber. 
  3. Always clean the cast iron sink with non-abrasive cleaning materials. Never use steel wools, abrasive sponges, or wire brushes to avoid scratching.

Which Is Better: Cast Iron Or Fireclay Sink?
