How to Remove Transmission Fluid Stains

Transmission fluid is a red liquid that lubricates the parts within a vehicle's transmission. Damaged transmissions can leak transmission fluid onto driveways and garage floors. Changing a vehicle's transmission fluid can also cause the liquid to drip or spill onto surfaces, producing oil-based stains. The longer transmission stains remain on surfaces, the more difficult they are to remove. Transmission stains can cause driveways and surfaces to appear aesthetically unappealing and improperly maintained. Fortunately, basic solutions can effectively 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.
