Things to Do When Cleaning a Porcelain Sink
Cleaning a porcelain sink requires a methodical approach using gentle yet effective cleaning agents to maintain its pristine appearance without damaging the surface.
The combination of baking soda and hydrogen peroxide creates a powerful cleaning solution that can tackle most stains and discoloration while being safe for the porcelain finish. Regular maintenance helps prevent the buildup of tough stains and guarantees the longevity of your sink's appearance.
- Wet the sink surface – Prepare the sink by dampening it with water to help the cleaning agents adhere better.
- Apply baking soda – Sprinkle a thin, even layer across the entire sink surface as a mild abrasive.
- Scrub with sponge – Use circular motions to work the baking soda into all areas of the sink.
- Add hydrogen peroxide – Pour over the baking soda to create a cleaning reaction.
- Wait 10-15 minutes – Allow the cleaning solution time to break down stains.
- Rinse thoroughly – Remove all cleaning residue with clean water.
- Tackle tough stains – Use a baking soda paste or lemon juice/vinegar mixture for stubborn spots.
- Regular maintenance – Clean weekly with dish soap and warm water to prevent buildup.
- Dry completely – Wipe down with a soft cloth to prevent water spots.
- Avoid harsh cleaners – Skip bleach and abrasive scrubbers that can damage the finish.
Things to Avoid When Cleaning a Porcelain Sink
Proper care of your porcelain sink is essential to maintain its pristine appearance and durability over time. While regular cleaning is important, using incorrect cleaning methods or products can cause permanent damage to the surface, diminishing both its aesthetic appeal and functionality.
Understanding what to avoid when cleaning your porcelain sink can help prevent costly repairs or replacements in the future.
- Harsh chemical cleaners like bleach – Can erode the porcelain surface and cause yellowing or permanent discoloration.

- Ammonia-based products – Can dull the glossy finish and potentially damage the surface.
