How to Remove an Iron Stain from Concrete How to Remove an Iron Stain from Concrete

What You'll Need
Vinegar
Lemon Juice
Sponge
Scrub brush
Oxalic acid
Broom
Bucket or water

An iron stain is rust-like in color and can be a blight on an otherwise clean concrete driveway or slab. Fortunately, removing rust and iron stains from concrete is not that difficult, and this simple step-by-step guide will show you how. Let's get started.

Step 1 - Sweep the Stained Area

Use a broom to sweep the area where the stain is located to remove as much dirt and dust as possible. If the area is really dirty, give it a quick wash to remove the dirt and grime.

Step 2 - Apply Lemon Juice or Vinegar

Use freshly squeezed lemon juice or household vinegar to apply to the stain. If using vinegar, any variety is fine and all work about the same. Allow the lemon juice or vinegar to soak into the stain on the concrete about 30 minutes before you continue. Then use a scrub brush to scrub the area where the juice or vinegar has soaked into the iron stain.

Step 3 - Rinse the Concrete

While scrubbing with your brush, start to pour clean water over the stained area. Scrub a few more minutes and then rinse the concrete. Repeat as needed.

Step 4 - Use a Commercial Cleaner for Tough Stains

If you have really tough stains, try a commercial concrete cleaning product that has oxalic acid as an ingredient. You can use the product much in the same way you use lemon juice or vinegar.
