How to Remove Transmission Fluid Stains
- 1). Sprinkle a thick layer of baking soda over the wet transmission fluid. Keep the baking soda on the driveway or surface for 30 minutes or until the fluid is completely absorbed.
- 2). Sweep up the oil-soaked debris with a broom. Dispose of the debris in an old coffee can.
- 3). Squirt 1 tsp. of liquid dish soap onto the remaining fluid stain. Spray the stain with a small amount of water from a garden hose to add suds.
- 4). Scrub the driveway with a nylon scrub brush to further clean the oily stain.
- 5). Rinse the driveway with water from the garden hose. Allow the driveway to air-dry.
- 6). Inspect the driveway for remaining traces of transmission fluid. If the stain persists, create a solution of 1/4-cup of trisodium phosphate with 1 gallon of warm water in a 3-gallon plastic bucket. Wear safety glasses and work gloves for protection.
- 7). Dampen a nylon scouring pad in the trisodium solution. Scrub the driveway with the damp scouring pad until the stain is completely removed.
- 8). Rinse the driveway with water from the garden hose. Again, allow the driveway to air-dry.
