Use a vinegar solution to dissolve the rust

  3. When the stains are no longer visible. Use a pressure washer to remove the rust residue on your driveway.

Follow this procedure to get rid of your driveway’s rust stains.

  1. Grab two to three lemons and cut them in half. The number of lemons you use will depend on the severity and number of rust stains present on your concrete driveway.
  2. Squeeze the lemon juice into a container.
  3. Pour the lemon juice directly onto the stained area and let it sit for ten minutes or longer. The acid from the lemon will dissolve and penetrate the rust.

Common questions about rust stains

What is the best commercial rust cleaner in treating my concrete driveway?

If you are looking for a commercial rust cleaner, consider a product with oxalic acid. Oxalic acid is a chemical that you can use to treat the rust.

The other property that can help you is trisodium phosphate. If you mix it with water and let it sit on the rust stains for 10 minutes, your rust will go away.

Always be careful when using harsh chemicals like these, as they can be harmful to your skin and health when mishandled.

Will rust remover damage the painted concrete in my driveway?

Yes. Acid, which is part of the property of commercial rust removers, can damage paint, leaving you with more problems to deal with. But there are alternative rust removers that you can use to remove rust stains while ensuring your concrete driveway’s paint is intact.

Look for rust removers that have less acidic properties. The pH determines how acidic the solution is. Try to examine the pH level of the rust remover that you will use and if it is seven or neutral, it won’t damage your painted surfaces.

What causes rust stains?

You could be suffering from rust stains on your concrete driveway because of the iron or metal objects that you put on your driveway. These objects can degrade and produce rust that can spread throughout your concrete driveways.

The most common cause of these objects producing rust is water, making your driveway vulnerable during rainy seasons. Don’t put too much metalwork on your driveway. Store these things in your storage room to avoid getting rust stains on your driveway.

Can I pressure wash my driveway to remove the rust on my concrete driveway?

No. You can pressure wash your concrete driveway, but using water alone will not help if you want to remove rust stains. It would be best if you used a concrete rust remover, lemon juice, baking soda paste, or vinegar as a solution for dissolving the rust stains.

If you use these ingredients and follow the methods above, and then follow up with your pressure washer, the rust stains will disappear.

The bottom line

Spotting rust on your concrete driveway can be dreadful. It’s a common problem for every homeowner, but you don’t need to continue suffering from rust anymore. Using the typical ingredients like vinegar, lemon juice, baking soda, and commercial rust remover, you can easily remove any kind of stains that bother your concrete driveway. Whatever option you choose, you will end up in the same outcome – and that is getting rid of rust stains.
