How To Remove Rust From Concrete

Need to know how to remove rust from concrete? Rust can infiltrate our driveways, patios and other concrete areas from a wide variety of sources. While the rust got there relatively easily, removing it can be another story altogether. Yet, ridding yourself of these pesky orange rust stains doesn't  have to be an impossible task. Natural and chemical methods exist to remove rust from concrete.

To remove rust from concrete naturally, you will need:

  • 2 lemons 
  • A bristled grill brush or abrasive sponge
  • Undiluted vinegar
  1. Prep the lemons. Roll your lemons between your hands or on the ground to loosen the juices within the lemon. You can also microwave your lemons for 30 seconds on high to loosen the juices. If your rust stains are excessively large, you may need more than two lemons.
  2. Apply the lemon juice. Cut the lemons in half and squeeze the lemons over your rust spots. Squeeze the lemons completely and then place them cut side down on top of the rust stain. Allow the lemons to penetrate the rust spot for five minutes before removing them.
  3. Scrub the spot. Using your grill brush or abrasive sponge, scrub the rust spot for five to ten minutes and rinse with water. If the spot is gone, then you are done; if not, continue on with the natural treatment.
  4. Treat with vinegar. Pour the undiluted vinegar over the entire rust spot which remains after the lemon treatment. Allow the vinegar to penetrate the spot for five to ten minutes.
  5. Scrub the spot. Using your grill brush or abrasive sponge, scrub the rust spot for five to ten minutes and rinse with water. If the rust spot is still there, you may need to pursue the chemical method of removing rust stains.

To remove rust from concrete chemically, you will need:

  • Trisodium phosphate
  • 1/2 gallon hot water
  • A bristled grill brush or abrasive sponge
  1. Mix the solution. Mix half a cup of trisodium phosphate with half a gallon of hot water until all of the trisodium phosphate has dissolved. Trisodium phosphate can be found at your local hardware or painting supply store.
  2. Apply the solution. Apply the solution of TSP and water to the rust spot and allow it to penetrate the spot for fifteen to twenty minutes.
  3. Scrub the spot. Using your grill brush or abrasive sponge, scrub the rust spot for five to ten minutes and rinse with water.
