Porcelain has many uses. Dishes, tubs, sinks, toilets and even decorative items are all often made from porcelain. There are even toys made from this stone-like substance. One of the largest drawbacks to this material is the fact that discolouration can easily occur. Rust and other materials can easily stain the surface of any porcelain item. While it may at first seem that these items are ruined after acquiring a brown stain, it is possible to remove the brown stains and return the porcelain object to its former usefulness.

  1. 1

    Use a scrubbing cleanser formula, such as Comet or Bar Keeper's Friend, on the stain. Sprinkle the stain with the cleaning powder and mix in enough water to form a paste. Let it stay on the stain for five to 10 minutes. Scrub with a scrubbing pad. Rinse with water. If the stain remains, continue to Step 2.

  2. 2

    Use a gentle pumice stone to scrape away at the stain. This is essentially scraping away the part of the porcelain that is brown. This should not be used on delicate porcelains, such as dishes. Rinse with water.

  3. 3

    Pour a solution of 40-percent peroxide (found in beauty supply stores) over the stain and let it stay overnight. The stain should be lifted the next morning. However, sometimes this method does not always work. If some of the stain seems to have lifted, repeat the treatment for another night.

  4. 4

    Mix some lemon juice with some salt to create a rough, moist powder. Scrub the salt into the stain and let stay overnight. The stain should be lifted from the porcelain and into the salt. Rinse with water.

  5. 5

    Spray some household oven cleaner on the brown stain. Follow the package directions and let sit for several minutes. Wipe away with a wet sponge.

Tips and warnings

  • Always wear gloves when working with chemicals of any kind.
  • Be sure to work in a well-ventilated area.
  • Always wear old clothes when using chemicals of any kind.
  • Test each cleaning method on a small part of the porcelain to ensure damage will not occur.
  • Hydrogen peroxide should not be used on coloured porcelain because it will cause discolouration.
  • Do not use bleach on porcelain because it can damage the enamel coating on the porcelain and often causes the glaze to separate and flake from the porcelain.
