! I was hoping that this product would do as good a job on my expensive cast iron enamel kitchen sink. It did not do the clean nor polish. Very disappointed with this product.That's what I get for trying to save money. Back to buying Delta Cast Iron Sink cleaner at $15 a bottle and using it sparingly.
Output:
negative
