One other thing that makes cast iron sinks better than most stinks is that they are available in many colors, designs, and configurations.  

Do Cast Iron Sinks Scratch?

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?

No. Cast iron sinks are very easy to maintain and clean. The well-polished and smooth enamel coating of cast iron sinks makes them non-porous. 

You can simply clean them by following these easy steps:

  1. Thoroughly rinse the sink with water after every usage. 
  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. 
  4. To remove stains, simply combine water and baking soda and apply the mixture to them. 

Which Is Better: Cast Iron Or Fireclay Sink?

Kitchen with fireclay sink and cabinetsCast iron and fireclay do have a lot in common. They’re both durable, easy to clean, beautiful, long-lasting, and they can both withstand harsh chemicals and other elements. They’re also both vulnerable to stains. 

However, although they’re both durable, a fireclay sink has its few advantages. Since it’s made out of clay-based ceramic that’s fired in a kiln at a very hot temperature and a protective glaze is fused to the clay, a fireclay sink can be more long-lasting than cast iron.

But then, the longevity of these sinks will still mostly depend on how the owner will take care of them.

In terms of weight, fireclay sinks are lighter than cast iron.  Fireclay sinks are more scratch-resistant than cast iron but they’re also more expensive than any high-grade sinks, including cast iron. 

But in terms of style and design, cast iron sinks are quite more elegant and eye-pleasing. 

We cannot conclude which one’s better between the two as they both have their own benefits and unique features. They’re also similar in numerous aspects. 

Both of these sinks can be a great option, but of course, it will still depend on your needs, budget, and preferences. The final decision will be yours. See our kitchen island with sink guide for more ideas.
