Porcelain sinks show every tea ring, mystery stain, and dingy water mark like they’re keeping score. This simple overnight soak tackles the buildup with two basic ingredients you probably already have under the sink or in the pantry (because the sink really doesn’t need to look older than the house).
Making a small batch yourself costs far less than buying a specialty porcelain cleaner. Using current Walmart pricing, 1/4 cup of dish soap plus 1/2 cup of white vinegar comes out to roughly $0.60 per treatment, and you can control the exact ingredients instead of adding fragrance boosters or extra cleaning additives you may not want.
You only need 2 materials for this method, and the mixture is used directly in the sink as one overnight treatment rather than bottled for later. Gather a measuring cup, then make sure you can close the drain before you start so the warm water and cleaning mixture can stand overnight.

Tips for Best Results
- Use this as an overnight soak so the mixture has time to work on set-in sink stains.
- Rinse thoroughly with hot water in the morning to clear away any remaining film.
- Skip scrubby pads and abrasive cleaners on porcelain finishes. Manufacturers such as KOHLER recommend using non-abrasive cleaning methods on vitreous china and porcelain sink surfaces to avoid damage to the finish: How to Clean & Care for Vitreous China Sinks.
Safety Information
- Follow the original warning exactly: Stand BACK, do NOT breathe the Fumes!!!
- Do not lean directly over the sink while adding the ingredients.
- Do not mix this treatment with bleach or other household cleaners.
- Keep children and pets away from the sink while the solution stands overnight.
Cost Breakdown
This is an estimate, and prices vary by store and region. Using current Walmart pricing, 1/2 cup of white vinegar costs about $0.22 based on a 32-ounce bottle at $1.76, and 1/4 cup of dish soap is estimated at about $0.38 based on typical current retail pricing for Dawn. That puts one treatment at roughly $0.60 total.

Frequently Asked Questions about Porcelain Sink Stain Remover
This method works best when you add the ingredients directly to the sink water and use it right away. The directions are written as a one-time overnight treatment, not a bottled cleaner.
Use several inches of warm water, exactly as directed. You want enough water to hold the cleaning mixture in the basin while it soaks overnight.
The method does not call for scrubbing. Start with the overnight soak, then rinse with hot water in the morning. If the sink still looks dingy, repeat the treatment rather than reaching for an abrasive pad.
The formula specifically uses Dawn dishwashing detergent, so that’s the version to follow if you want to keep the method exactly as written.
Yes, this treatment is written for a porcelain sink. If you need help with a different surface, use a cleaner matched to that material instead of assuming one formula fits everything.
Because the original directions include a very clear warning to stand back and avoid breathing the fumes. Follow that warning exactly and don’t hover over the sink while you add the ingredients.
Overnight is the stated soak time. There’s no verified direction here for extending it beyond that, so rinse it out with hot water the next day as written.
Some older stains need a second round. Repeat the same overnight treatment before trying anything more aggressive on porcelain.
Rinse with hot water. That’s the final step in the original method, and it helps flush away the loosened residue and soap film.
