How to clean a cast iron sink

Several months ago (as part of our kitchen remodel), we decided to pour our own concrete countertops.  You can find part 1, part 2 and part 3 here.

If you're new here, welcome! You can follow me on Instagram (greywoodmama) for more behind the scenes stories of our remodeling projects!

If you've been following me on this journey, you know that this remodel process is taking WAY longer than expected. But, I'm ok with it - we are learning SO much!


Because of the way things turned out with the concrete project, we decided to get a new sink. I’ve always wanted a single bowl sink, so we landed on a cast iron single bowl sink – a white one.


Friends, it’s so beautiful.

But now that we’ve had it for several months, I can tell you honestly how I feel about it.

But before we do, I know you'll want to come back to this later. So go ahead and PIN it!



It stains easily.

I mean what did I expect, it’s white.  By this I mean, if you put tomato sauce or black tea in the sink, it’s going to leave some color behind.  I can live with it for a little bit, but after time it doesn’t look so beautiful.


(I tried to take a picture of the color, but you can't really tell in the picture.  Just trust me on this one.)


Metal isn’t very friendly.

If a metal grill utensil or something else sharp scrapes the bottom of the sink, it leaves a nice grey mark.   Let me be clear, it DOESN’T scratch it, just leaves a colored mark.


It holds a lot of dishes.

When we are done cooking, it’s so nice to put all the dishes in the sink to rinse off or wash.  That big bowl does come in handy sometimes!


Did I mention it’s beautiful?

Before we started this journey of redoing our entire house, I knew exactly what I wanted.  And now that we’ve been living with some things for a while, I can definitely say it’s been a learning experience.

I think there’s certainly a trade off when it comes to things like a cast iron white sink.  And I would have to say, if we had kids, I don’t think I would want it.


Yes, it’s beautiful.  But right now, I have time to clean it and worry about it.  But if you’re someone who doesn’t want to take the time to clean the sink often or worry about the colored marks on it all the time, I definitely would not get this type of sink.

So, how do I clean it? It’s super simple.  Here’s the secret.

Baking soda.

That’s it.  Sometimes I add a little bit of vinegar as well.

Sprinkle the baking soda all around, then use a paper towel and a little water to scrub the sink.  It takes the color and the grey marks right off.


I probably do this once a week to keep it looking nice and clean.


Happy cleaning! And if you have your own tips for cleaning a cast iron sink, please share them with me!
