Q&A for How to Clean and Shine a Porcelain Sink

Consider investing in a good whole-house water filter that filters out iron and other noxious particles.

Use warm or hot water and then polish with a dry towel or cloth. I have tried vinegar, but the warm or hot water is better. Sometime you will have to scrape with a razor knife to loosen hard dried food. Then vacuum, apply the warm water, mop lightly, let it dry, and polish with a dry cloth. Porcelain is like glass, the harder you polish, the better.

If you don't have a cleaning product that is designed specifically to cut grease, use soap and water and lots of scrubbing.

Use hot distilled vinegar. Line the sink with towels. Pour the hot vinegar over them. Let it soak for at least 30 minutes, then rinse thoroughly.

You can use lemon juice and table salt to get rid of the rust. Use with caution, as this can dull the finish of the porcelain. It is a good idea to install a good water system to prevent staining in the future.
