How to Remove Rust from Concrete

How to Remove Rust from Concrete?

When metal gets wet, it leaves behind an ugly orangish color on whatever surface it was on. Perhaps you are familiar with this reaction from the last time you left your tools out on the driveway, or from your metal patio furniture. Perhaps that is why you are reading this article in the first place. If you are ready to get rid of those unsightly rust stains, then you came to the right place. Wilson’s Power Washing and Sealing is going to explain how you can get rid of rust stains on concrete surfaces.

Depending on how long the rust stain has existed, there are two categories for treatment. If you are not sure how old the stain you are concerned about is, we recommend you start with the minor stain solution first. If the stain persists, move forward with the major stain solution.

Minor Stains

Before you begin, thoroughly clean the stained surface. Simple dish soap should suffice. You really want to rid the area of dirt, grime, and debris so that the solution is not inhibited. The key to lifting the rust stain is using a strong acidic ingredient, such as lemon juice or white vinegar. Do not dilute either one. Pour the lemon juice or the vinegar onto the spot. Let it sit for 10-15 minutes. After it has been allowed to soak into the area, take a stiff wire brush and scrub away. If you are worried that your concrete is too delicate for a wire brush, you can use something gentler like a nylon brush, although it may not be as effective. Once you are done scrubbing, rinse the area and let it dry. You may need to repeat the process again until you are satisfied with the results.

Major Stains

If the household cleaning solution does not seem to be working, the next step you can take is to apply a commercial grade rust remover. Just be careful! It is very important to read the manufacturer's safety instructions. Equip yourself with the proper PPE when dealing with strong acids. Gloves, eye protection, and a long sleeve shirt are all important to have on when applying the cleaner. The steps that follow are like those for minor stains. Apply the solution, let sit, and then scrub and rinse.

If you're still not getting the results you want, or you just want to get things done right the first time, just call Wilson’s Power Washing and Sealing. We are the rust removal experts in the Washington DC Metropolitan Area. We can remove rust from nearly any surface.
