How to Get Rid of Transmission Fluid Stains on Concrete

Quck answer

To remove transmission fluid from concrete, follow these steps:

1. Act quickly: The sooner you start cleaning, the better chance you have of removing the stain completely.

2. Absorb the fluid: Use cat litter, sawdust, or baking soda to absorb as much of the transmission fluid as possible. Sprinkle it over the affected area and let it sit for a few hours.

3. Sweep it up: Use a broom or a brush to sweep up the absorbent material along with the transmission fluid. Dispose of it properly.

4. Apply a degreaser: Use a degreasing cleaner or dish soap mixed with hot water to scrub the remaining stain. Let it sit for a few minutes before scrubbing with a brush.

5. Rinse thoroughly: Use a hose or a pressure washer to rinse off the degreaser and any residue. Make sure to remove all traces of the transmission fluid.

6. Repeat if necessary: If the stain is still visible, repeat the process until it is completely gone.

By following these steps, you can effectively remove transmission fluid stains from concrete.


When transmission fluid leaks and leaves a reddish stain on concrete driveways, it’s important to remove it as soon as possible. Petroleum-based fluids are easier to remove if dealt with immediately. Although concrete is a hard surface, it is also porous and absorbs liquids deeply. While it may be difficult to completely remove older stains, you can make them less noticeable in about an hour. By using the right chemicals, you can fade or eliminate the surface portion of the stain.

Removing Fresh Transmission Fluid Stains

Step 1

Spread an even layer of kitty litter, about 1 inch thick, over all fresh transmission fluid spots. Allow it to absorb the fluid for approximately 30 minutes, then sweep it away with a broom and dispose of it.

Step 2

Mix 2 cups of liquid dish detergent with 1 gallon of hot water. Pour the soapy water over the fluid stains.

Step 3

Use a stiff nylon-bristle brush to scrub the spots. Rinse with clear water.

Step 4

Repeat the process of scrubbing with hot soapy water and rinsing until the stain is completely gone.

Removing Older Transmission Fluid Stains

Step 1

Pour a small amount of paint thinner onto the old transmission fluid spots. Allow it to soak for 15 to 20 minutes.

Step 2

Vigorously scrub the area with a nylon-bristle sponge. Absorb the dark liquid using paper towels.

Step 3

Mix two cups of liquid dish detergent with a gallon of water. Scrub the area using the nylon brush and rinse with clear water.

Step 4

Dispose of the paper towels in a disposable metal container or burn them in a safe area.
