How to Remove Rust from Tile Grout

There can be different ways of removing rust from tile grout, which may or may not work out well. However, the cleaner that usually works in such a cleaning exercise is baking soda.

Required Materials

  • Baking soda
  • Suggested baking soda additives:
  • Vinegar


    Hydrogen Peroxide

    ½ cut lemon

    Pencil eraser

  • Commercial cleaner
  • Straight vinegar
  • Cut vinegar
  • Bleach and water

Required Tools

  • Tooth brush
  • Wire brush
  • Sponge
  • Rag

Cleaning Rust-stained Tile Grout

In every method of cleaning with a liquid agent, the cleaner must be left to stay for a while to allow it to act on the grease. Depending upon the cleaning agent, you can generally tell when the cleaning has reached its most potent when the foaming action created by the combination of agents has stopped. When the bubbling begins to stop, use your toothbrush or other cleaning element and begin to clean the grout.

Commercial Cleaning Products

Apart from the household remedies that are available, you can find many commercial cleaning products in the market. They usually claim to be able to remove deeply ingrained rust stains.

Some products also offer a covering agent that will make the grout white again by covering it with a layer of chemical white.

The Use of Baking Soda

With all said and done, baking soda remains a very powerful cleaner for tile grout. Baking soda causes the dirt to dissolve in water and so is very effective in cleaning tile grout. When used with a sponge or scrubber, it forms a mildly abrasive scouring powder. For quicker cleaning of tiles near the kitchen sink, it can be used along with a few drops sprinkled from a freshly cut lemon.

When cleaning floor tiles, a bucket of hot water and a box of baking soda can do the trick of getting rid of the unwanted rust. This mixture should be sponged liberally onto the tiles and allowed to stay for several minutes. It should then be rinsed well to give the desired results.

    It would be nice if the author mentioned which methods work well and which don’t. The way the required materials are listed suggest you would use all of them together.
