2 Methods to Clean a Black Cast Iron Sink
Tools You’ll Need
- Dishwashing soap (Should be non-abrasive)
- Sponge or rag (Do not use abrasive brushes like steel wool or wire brushes)
- Baking soda (For deep cleaning)
- White Vinegar (For deep cleaning)
Step1: Prepare soap mixture
Set aside a bowl of hot water and add the dishwashing soap to it. You can use other types of soap so long they are non-abrasive. Using a soap that has grease-cutting properties would be a plus. For example Kohler Cast Iron Sink Cleaner.
Step2: Apply the soap mixture to the surface of the sink
Using the sponge or rag that you have, rub the soap mixture on the surface of the sink. Rub the top of the sink, the sides, and the basin. Avoid abrasive sponges or anything that can damage the porcelain coat of your iron sink.
Step 3: Wash off the soap with water
Open the tap and use the water to rinse the soap. Find a way to wash off areas that the faucet can’t reach. Make sure that the soap mixture is thoroughly rinsed off the sink.
Step 4: Towel the sink dry
Using a paper towel, a dishrag, or any dry piece of cloth, towel the sink dry. Make sure to clean all the extra water as porcelain sinks are vulnerable to watermarks. Make sure that the soap you are using is both non-abrasive and environmentally friendly as it might come in contact with other food utensils.

Deep cleaning is better for older and dirtier sinks. It is also good at removing stubborn stains from foods like coffee, berries, and tea bags. Depending on your kitchen sink, you might need a deep clean to get marks off the cast iron sink.
Step 1: Set aside a bowl for your deep cleaning mix
Add vinegar and baking soda to the bowl and mix to form a paste. Use a soft sponge and apply the baking soda paste to the sink. Apply it to tough stains, spots, and rub in a circular motion until you get out all the stains.
Step 2: Rinse thoroughly
Continue to repeat the above steps until you get your desired results. For tough stains and very dirty black cast iron sinks, this might mean repeating the process 2-3 times per deep clean.
Step 3: Dry the sink’s surface
Wipe off water and any cleaning paste still left on the sink’s surface. Use a rag or paper towel that’s gentle and won’t damage the porcelain finish.
When using soaps and other cleaning agents, make sure to avoid contact with your eyes and skin. Using a hand glove will go a long way in preventing the soap from burning your skin.
For a deeper clean, it is advised that you apply the cleaning paste to the stubborn areas. You can leave it overnight. Return in the morning and wash off the cleaning paste using clean water.
