How to Clean a White Cast-Iron Sink

When you're cleaning cast iron sink basins, you want to make sure that you aren't using super harsh products that will damage the sink. Although you can use products like dish detergent, baking soda and vinegar, it is recommended that you use a cast iron sink cleaner, such as the Kohler brand, because there's a guarantee that it won't damage your sink in the long run. If you have other cast iron surfaces, you can use Kohler products on them, as well.

Cast Iron Sink

Cast iron sinks are a popular option because they look beautiful in the kitchen, and they are long-lasting. You can also find cast iron sinks in a variety of colors, styles and price points.

According to Ceco Sinks, cast iron sinks are made up of two layers. The first layer is a heavy, durable iron alloy that is coated in a thick enamel top layer. These two layers have a surface with a glossy finish.

The polished enamel of cast iron sinks makes them nonporous, which means they are stain-resistant and easy to clean. They also hide water spots and streaks very well. Although they are easy to clean, you want to make sure you are cleaning them correctly because they are heavy and brittle. Since they have a smooth and glossy surface, you should avoid using harsh cleaners to clean the surface of the sink.

Cleaning Cast Iron Sink Basins

When you're choosing a cleaner for cleaning cast iron sink basins, you want to make sure you're buying the appropriate cleaner. According to Kohler, you have to take into account a couple of factors before choosing a cleaner. These factors include the hardness and temperature of the water you're using to clean the sink, measurements of the ingredients, changes in cleaning formulas and the condition of the sink that you are cleaning.

Kohler recommends that you use cleaning products such as the Kohler k-1012525 cast iron cleaner (8 oz bottle), Fantastik Antibacterial Heavy Duty, Formula 409 Antibacterial All-Purpose, Green Works All-Purpose or Soft Scrub Gel with Bleach.

The Kohler cast iron tub cleaner does a great job because you can use it on the sink and other cast iron surfaces. Also, it easily removes pot marks, rust and other blemishes. In addition to these promises, the cleaner will bring back the original shine of the cast-iron surface.

When you're using the Kohler cleaner, test the solution in an area that is not highly visible before cleaning the entire sink. Also, make sure to wipe the surfaces clean of any solution, and never let the cleaner soak. When cleaning, use a soft, dampened sponge or cloth.

Additional Cleaning Tips

When you are cleaning a cast iron sink, you must rinse the sink thoroughly. Always remember that after you wash your sink, you will need to wipe it dry after every time that you use it. If you do have hard-to-clean stains, then you can use abrasive cleaners. But try to stray away from using them often. Even though you can use abrasive cleaners sparingly, don't use steel wool, wire brushes or abrasive sponge pads because this will damage the sink.

Also, don't leave stray items like coffee grounds, tea bags or others that will stain your sink. To prevent scratches, you should consider purchasing sink accessories like bottom basin racks. Bottom basin racks will prevent scratches and any other materials from staining your sink.
