David asked: How do I clean my asphalt driveway? We have four small spills of power steering fluid on the asphalt driveway. I would like to know how to clean it. Thank you.
This simple method of cleaning asphalt will take care of most spills and stains, including difficult automotive messes.
You Will Need:
- Trisodium Phosphate (TSP)
- Long handled push broom with stiff bristles
- Eye protection
- Rubber gloves
- Hose connected to running water
Steps to Remove the Stain:
- Begin by protecting yourself with protective eye-wear and rubber gloves.
- Read the labels carefully and observe all warnings and precautions.
- Mix a solution of TSP and water in the bucket. Check the label for the appropriate ratio to use for your particular job.
- Pour enough of the TSP solution on the stain to cover it. If the stain is old or severe, you may want to allow the solution a few minutes to soak into the stain and loosen it before scrubbing.
- Scrub the area vigorously with the stiff-bristled broom.
- If the spot doesn’t come off, scrub it again with full strength household bleach after rinsing the area well.
- Rinse thoroughly with a hose.
- If any stains remain, but have lightened, repeat the above steps until they are removed.
Additional Tips and Advice
- If this home cleaning solution doesn’t work, try a commercial asphalt cleaning product. Make sure to select one made for asphalt, as some concrete cleaners can damage asphalt. These products can be found at hardware and home improvement stores.
- Wear eye protection and rubber gloves when working with cleaning agents.
- Watch the runoff water if there are nearby shrubs and plants. The TSP and bleach can be harmful to these and cause dead, patchy areas.
With my permission, my neighbor has been using my driveway. I’ve noticed two oily puddles about 6 in. in diameter. Is there anything I can use to just absorb the oil until she has another place to park?
Just had my driveway redone with new asphalt. Unfortunately, the contractor also power washed the connecting stone paver walkway and used stone dust to fill in cracks between the pavers. Stone dust has washed out onto the driveway, leaving an ugly grey stain which does not wash off with the garden hose. I am afraid the stone dust is “set” in the new asphalt? Any suggestions on removal?
