7 Cast Iron Sink Care Tips

Many people prefer a cast iron sink over stainless steel due to the fact that the enamel holds up for many years, as long as it receives good care. Although a cast iron sink is heavy, it still needs to be treated well, looked after and maintained regularly to remain looking good.


A cast iron sink can stain quite easily. To prevent this happening, don’t leave used tea bags or coffee grounds in the sink. The same applies to other foodstuffs, especially if damp. These can cause stains that can be hard to eliminate. Removing the cause is a great deal easier.


To avoid scratches to the enamel of a cast iron sink, use a rubber mat in the sink. You could also use a rinse basket for the job. It will make the sink easier to clean and avoid any cutlery or other sharp objects coming in contact with the enamel.


Each time, once you’ve finished using the sink to wash dishes or peel vegetables, rinse it out and dry with a soft cloth. This will help to keep it in the very best condition and also make sure you don’t leave water marks in the sink.


You can clean a cast iron sink using just dish soap and warm water, rubbing it down with a soft cloth and then rinsing and drying with another cloth.

For strong cleaning, try putting white vinegar on a cloth and rubbing down the sink. This will get rid of dirt and many stains that can accumulate. Always rinse and dry the sink after. Baking soda is also good for a heavy-duty cleaning. Wet the sink and then sprinkle baking soda into it. With a nylon scrub brush (this won’t scratch the surface), scrub the sink. When finished, rinse the sink and then dry it.


Where there are stains you can’t remove with the agents above, turn to commercial abrasive cleaners. Be careful, however, as these can very easily scratch the cast iron sink. Use very lightly and scrub with a rag, not a brush. You should be able to remove most, if not all, the stain. Apply more abrasive and repeat until the stain has vanished and then rinse and dry the sink.

Things To Avoid

Never use wire brushes, steel wool, or sponges with abrasive sides (those intended for no-stick pans will work, but only with care). These can quickly form scratches on the enamel surface of the cat iron sink. You should also take care not to drop things into the sink as that can chip the enamel. Apart from not looking good, repairing it can be time-consuming and awkward-or expensive if you pay someone else to do it.

How Often To Clean

You should rinse out the sink after each use and give it a cleaning every week. It only takes a few minutes, which is a worthwhile investment to keep the sink sparkling for years on end.
