How to Remove Rust Stains From Porcelain Tiles

If you have rust stains on your porcelain tiles, there are a few ways to remove them. The most common and easiest way of removing the rust stain is by using a poultice of household items like salt and vinegar or lemon juice and baking soda. However, you can also use muriatic acid for this task, damaging the tiles more than other methods.

There are some more complicated ways of removing these stains, including using hydrogen peroxide with ammonia to bleach out the stain where it is not chemically possible due to being absorbed into porous materials such as ceramic tile grout lines. In this article, we’ll explore how to remove rust stains from porcelain tiles.

Materials You Are Needed

  1. Rubbing Alcohol
  2. Hydrogen Peroxide
  3. Bleach
  4. Toothbrush or Scrub Brush with stiff bristles
  5. Water
  6. Mop
  7. Rags or Paper Towels

9 Steps to Follow on How to Remove Rust Stains From Porcelain Tiles

Step One: Determine if the Stain is Rust

You should test whether what you think is rust is rust. Mix a little bit of dish soap with hot water and mix it around. Using a toothbrush, scrub the area where the stain was to see if it starts bubbling up any rust stains mixed in with dirt or grime. If this doesn’t happen and you’re sure it’s rust, move to step two.

Step Two: Apply Baking Soda Paste with a Toothbrush

Mix baking soda with just enough water to create a thick paste painted on the porcelain tile without dripping all over the floor. Next, paint this mixture onto the completely dry stain. Allow it to sit for about 20 minutes before you try scrubbing the area.

Step Three: Scrub the Stain with a Toothbrush and White Vinegar

Use a toothbrush to scrub vigorously at the stained area. If this still doesn’t remove the stain, add about two tablespoons of vinegar into your baking soda paste mixture and continue scrubbing. The vinegar will help the baking soda get deeper into the porcelain tile.

Step Four: Apply Hydrogen Peroxide

Using a paintbrush, apply hydrogen peroxide to the area and allow it to sit for at least 20 minutes. You may notice that the stain starts turning yellowish as you wait this amount of time. Once you’ve waited long enough, begin scrubbing with a toothbrush again to remove the stain.

Step Five: Apply Baking Soda Paste with a Paintbrush

After you’ve scrubbed the stained area again, use a paintbrush to apply more of the baking soda paste mixture. Allow it to sit for about an hour before rinsing the paste away.

Step Six: Rinse with Water

You can use a spray bottle or cup to rinse the area with water after the paste has been sitting for an hour. If you notice that there are still rust stains in the porcelain tile, continue following steps three through five until all of the stains are removed.

Step Seven: Clean the Tile Using a Grease-Cutting Dish Soap

Once your tile is completely rinsed with baking soda paste, you need to clean it. Use a grease-cutting dish soap with water and scrub the entire surface until all residue from the stain is gone.

Step Eight: Remove the Water with a Shop Towel

Once you’ve scrubbed the surface until it appears clean, use a shop towel to remove all of the water that’s remaining on the tile. A fan may be used as well if there isn’t much wind where you are or if you don’t own a shop towel. Repeat the cleaning process again if the rust stains are still visible.

Step Nine: Apply a Clear Coat to the Tile for Long-Term Protection

Once you have completely removed all rust stains from the porcelain tile, your last step is to apply a clear coat of polyurethane varnish or paint so that new stains can’t form. This will seal the fresh look of the tiles and keep their shine intact.

Step Ten: Test Your Porcelain Tile for Stains

Before you attempt any cleaning process, test the porcelain tile in an inconspicuous area. Make sure that your chosen method of stain removal does not remove the glaze on the tiles as well.

If the tiles are still glazed, use a single-sided razor to gently scrape off the glaze on the stained area before applying any cleaning method. This will allow for more effective stain removal. If you use the steps outlined above for how to remove rust stains from porcelain tiles, you can do it yourself.

Is Vinegar Safe for Porcelain Tile?

At its core, vinegar is a diluted form of acetic acid. Of course, the concentration of the acetic acid in regular household white distilled vinegar is much higher than that of car battery acid or toilet bowl cleaner, but it still has enough potency to irritate human skin and damage most surfaces if used incorrectly.

If you are intent on using vinegar to remove rust stains from your porcelain bathroom tile, make sure that it’s diluted with ample amounts of water. Do not use vinegar undiluted. Doing so may result in damage to the substrate. Instead, dilute the vinegar with water, and you will be able to remove rust from porcelain bathroom tile without damaging the surface.

When You Should Remove Rust Stains From Porcelain Patio Tiles?

Rust stains on porcelain tiles are not a big problem and can be easily removed. However, you should remove rust stains from porcelain tiles if they are built into the tiles. For example, showerheads and knobs for drains may be made of metal that rusts over time. If you have rust stains on these parts of your porcelain tiles, you should remove them with a metal polish.

Metal polishes are available at hardware stores, drugstores, and discount department stores. They contain a mild abrasive that buffs out the rust stains. If you have tiles where the surface is made of metal and has rusted, you should also remove those rust stains from porcelain tiles.


The key to removing rust stains from porcelain tiles is using a product that will remove the stain and seal it. That way, if there are any more spills of rusty water in your home, you’re not going to have anything but clean tile on which they can be spilled.

For best results, try buying a neutralizing cleaner such as Zep Commercial Rust Remover & Sealer or BKF Porcelain Tile Cleaner with Neutralizer. By following these simple instructions for how to remove rust stains from porcelain tiles at home, you’ll save yourself time and money while also making sure your floors look fantastic!
