How To Remove Rust Stains From Concrete Patio

What You’ll Need

  • Oxalic acid 
  • A ventilator
  • Protective gloves 
  • A scrubbing brush
  • A pressure washer or garden hose
  • A broom

Steps

  1. Mix The Acid Solution

    Depending on the oxalic acid you buy, you will need to follow different steps to mix the solution. I recommend carefully reading the instructions that come with the product and taking safety precautions.

    Oxalic acid is hazardous, particularly to your respiratory system and skin. Therefore, I recommend using a P100 ventilator , mixing the solution in a well-ventilated area, and covering your hands with gloves.

  2. Clear The Area

    Sweep any dust and dirt away from the stained areas. You want the stain to be as exposed as possible to apply the acid. You can use this method if you use metal outdoor patio furniture that has left rust stains on the concrete.

  3. Scrub

    Place the acid solution on top of the stains and start to scrub with your scrubbing brush. You may need to scrub hard to remove stubborn stains

  4. Rinse

    Use your hose or pressure cleaner to rinse the surface and remove the acid completely. For older stains, you may need to repeat steps 3 and 4 a couple of times. Let it dry before you touch the surface again.

How To Get Out Mildew Stains From Concrete Patio

What You’ll Need

  • Chlorine bleach  
  • A spray bottle
  • Tap water
  • Old towels or rags
  • A scrubbing brush
  • Eye goggles
  • A pressure washer or a garden hose

Steps

  1. Protect Your Lawn And Yourself

    Bleach will kill your lawn and flowers if you allow the solution to make contact with them. If you have grass or garden close to your patio, I recommend covering the exposed areas completely with old towels.I also recommend covering your body in old clothes and protective gear. Bleach can stain your clothing so put on items that you’re not worried about damaging. You should also wear goggles or other eyewear in case of spillage.

  2. Prepare Your Bleach Solution

    Ensure that you choose chlorine bleach instead of oxygen bleach, or else you risk removing the stain but not killing the mildew spores. This means that it will keep coming back, and you will need to clean more frequently.

    Dilute the bleach by adding one part to two parts of tap water. Make enough so you can cover all the stains. Put your solution in a spray bottle, and take care not to shake it up until the lid is properly closed. Otherwise, you risk it spilling and harming your skin.

  3. Clear The SpaceRemove any items, like outdoor furniture, from your concrete patio. You may also like to sweep the area to remove any residual dust and dirt.

  4. Apply The Bleach SolutionUse the spray bottle to cover the stains completely. For light stains, you may only need to leave it there for 5 minutes. However, older or heavier stains may require a full 30 minutes of exposure to remove them.

  5. Remove The StainsUse your scrubbing brush over the stains and work in the bleach solution. You may need to go over different sections a few times to get the stain out fully.

    You can rinse off the solution with your garden hose or pressure washer. If you accidentally got any bleach on your plants, make sure that you clean them off too.

    Let the patio dry thoroughly before walking on it or replacing your outdoor furniture.
