How to Remove Dirt Stains from Concrete
First, how in the world do dirt stains get on concrete anyway? Isn’t concrete just a big rock? Yes, but the problem isn’t the dirt itself; rather, it’s the color of the dirt. Different types of dirt can stain your concrete surfaces if the color is different than that of your concrete (think red shale and other clays). It can also become imbedded in some of the uneven surfaces of the concrete.
What you will need:
- Push broom
- Powder-style laundry detergent
- Powdered bleach (optional)
- Water Hose
- Make sure that you have protective gear on. Gloves and slip-proof shoes are recommended while you do this, so that you don’t get blisters and you don’t fall.
- Take your push broom and sweep all of the concrete thoroughly. Go through it several times if you have to; you want to make sure that there are no particles on top of your concrete.
- Take your water hose and wet the entire surface.
- Sprinkle the whole area with your powder-style laundry soap. The brand doesn’t matter, just make sure that it is powder and not liquid. If you see stains, make sure to cover those areas very well.
- Optional: You can also use powdered bleach on the stains to try and restore the concrete’s natural color. If you are concerned that the bleach may make your concrete too light, skip this step.
- Take your broom and use it like a giant scrub brush, scrubbing the entire concrete surface with it. Take extra care to scrub the areas that are stained so that the stains start to come out.
- After you’ve scrubbed the surface to your liking, then take your water hose and rinse everything off of the surface. Make sure to get all of the laundry detergent off of your concrete or you could end up with some discolored areas.
- Allow the area to dry for a day or so. If there are still stains, repeat the process in about a week. You should be able to do this about twice a year without any issue.
