Using Dishwashing Soap

Step 1: Collect All the Required Items

  • Baking soda
  • Hot water
  • Dishwashing soap
  • Soft sponge or piece of cloth
  • Distilled white vinegar
  • Spoon
  • Small container
  • Wine bottle cock
  • An ideal cast iron sink cleaner

Step 2: Clear the Sink

After assembling all the items you require for the cleaning process, it’s time to get rid of anything in or on the sink.

Start by removing all the utensils and other kitchen stuff if dealing with a kitchen sink.

Step 3: Put Dishwashing Soap in Water

If you don’t have the sink cleaner, do not panic. A reliable dishwashing soap will work out fine. Some dishwashing soaps do not remove grease properly.

For optimal results, use a dishwashing liquid containing a grease remover. Also, the sink cleaners and soaps come in various enticing fragrances. Choose one with a smell you like.

Add two tablespoons of the sink cleaner or dishwashing liquid or soap to four liters of hot water and mix well.

Step 4: Clean the Sink Using the Soap Solution and a Clean Sponge

After mixing the dishwashing soap with hot water, dip a clean, soft sponge, piece of cloth, or rag into the solution. Then wring out the excess solution and start scrubbing the sink.

Never use abrasives like wire brushes, hard sponge pads, or steel wool, for they will damage your white cast iron sink’s surface.

Start with the sink’s bottom, then upwards towards the top while cleaning the sides.

Finish by scrubbing the sink’s top and the surrounding countertop. As you wash, you will start seeing foam mixed with dirt forming up.

Step 5: Rinse the Sink Using Clean Water

After scrubbing all the areas of the sink, it’s time to rinse it. Open the sink’s faucet and allow water to run down. If the spout is flexible, turn it to various parts of the sink, rinsing out the cleaning mixture with dirt.

For those parts the water can’t reach, put water in a container and pour it on them. Rinse down every aspect of the sink until the cleaning mixture is gone.

If the sink still has some dirt or stains proceed to the next step.

1. Mix Vinegar with Baking Soda

Take a small container and mix vinegar with baking powder. Mix until moderate paste forms. If the mixture becomes too thick, loosen it by adding some more vinegar.

2. Put Some Vinegar and Baking Powder Paste on a Sponge and Start Scrubbing

After the paste has gained the right consistency, scoop some of it using a soft cleaning sponge, cloth, or rag. Then rub it on the entire sink, concentrating on the areas with visible dirt or stains.

3. Rinse the Sink

Use the procedure discussed above to rinse the sink. Ensure all scum and dirt are gone. If you still find some pot marks after rinsing, proceed to the next step.

Scrub the marks using a quality wine bottle cork until they are all gone.

5. Rinse the Sink

After removing all the scratches, rinse the cast iron sink with clean water, as discussed earlier.

6. Use a Clean Dry Cloth to Dry the Sink

You can repeat the above steps until you are happy with the results. Use a reliable cast iron sink cleaner or dishwashing soap and warm water to clean the sink for your daily routine.
