1. Detergent and Water:
- Create a mixture of liquid laundry detergent and water. The ratio can be roughly one part detergent to ten parts water.
- Apply the solution to the stain using a sponge or a brush.
- Scrub the stain gently with the sponge or brush. Start from the edges of the stain and work towards the center.
- Rinse the area thoroughly with water.
- Repeat the process if the stain persists.
2. Degreaser:
- Use a commercial degreaser product specifically formulated for concrete surfaces.
- Follow the instructions provided on the product label for mixing and application.
- Apply the degreaser to the stain and let it sit for the recommended time.
- Scrub the stain with a brush or a sponge.
- Rinse the area thoroughly with water.
3. Trisodium Phosphate (TSP):
- Mix trisodium phosphate with water according to the package instructions.
- Apply the solution to the stain and scrub it with a stiff brush.
- Rinse the area thoroughly with water.
- TSP is a strong cleaner, so be sure to follow the instructions and use gloves and eye protection.
4. Vinegar and Baking Soda:
- Sprinkle a generous amount of baking soda over the stain.
- Pour vinegar over the baking soda and let it foam up.
- Allow the mixture to sit for a few minutes.
- Scrub the area with a brush.
- Rinse the surface with water.
5. Pressure Washer:
- If the stains are stubborn, consider using a pressure washer.
- Be cautious not to use too high a pressure, as it could damage the concrete.
- Use the pressure washer in combination with a cleaning solution to increase its effectiveness.
6. Professional Cleaning Services:
- If none of the above methods work, you may need to hire a professional concrete cleaning service. They have the expertise and equipment to remove tough stains effectively.
7. Preventive Measures:
- To prevent auto stains on concrete, try to clean up any spills immediately.
- Avoid parking your car on the same spot for extended periods, as this can increase the risk of stains.
- Use protective mats or drip trays under vehicles that are prone to leaks.
Remember that the specific cleaning method you choose may depend on the type of auto stains and the condition of your concrete surface. It is always recommended to test a small, inconspicuous area before applying any cleaning solution to the entire stain.
