Oil stains and tread marks can be an eyesore on an asphalt driveway coating. Washing the asphalt will bring back the dark surface. Regular maintenance will prevent any further discoloration.
Step 1 - Safety
Wear protective eye wear and rubber gloves for this cleaning process.
Step 2 - Prepare the Asphalt
Use the push broom to sweep the asphalt driveway and remove all of the dirt, dust, and debris.
Step 3 - Wash the Asphalt
Fill the one-gallon bucket with warm water. Add ½ cup of laundry soap to the warm water. Mix the water and soap until the solution is bubbly. Pour a small amount of the soap solution on to the driveway. Use the push broom to scrub the asphalt, especially in any areas where there are cracks or holes. Continue the process until the entire driveway has been washed. Use the spray nozzle on the garden hose to spray rinse the soap and residue from the asphalt.
Step 4 - Mix the Stain Removal Solution
Fill another one-gallon bucket with warm water. Add two cups of trisodium phosphate cleaning agent.
Step 5 - Remove the Stains
Apply the stain removal solution to any stains on the driveway. Let the solution sit on the stain for 20 minutes. Scrub the stained areas with the push broom. Rinse the asphalt to remove all of the residue. For stains that remain, apply a small amount of bleach to the area. Allow to sit for five minutes. Rinse the bleach from the asphalt.
Step 6 - Seal the Asphalt
Choose a water based, eco-friendly asphalt sealer. Apply the asphalt sealer to the driveway, following the directions provided by the manufacturer.
