As a professional in the field of home maintenance and cleaning, I've encountered various challenges when it comes to removing stubborn stains, especially oil stains from concrete surfaces. Here’s a comprehensive guide on how to tackle this issue effectively.

Identifying the Stain
Firstly, it's crucial to identify the type of stain you're dealing with. Oil stains can vary in composition, and some may be more stubborn than others. The method of removal can differ based on the stain's age and the type of oil.

Preparation
Before you start, ensure the area is clear of any debris and that you have the right tools and materials. You will need:
- A stiff bristle brush or a scrubbing pad.
- Protective gloves to prevent skin irritation.
- Safety goggles to protect your eyes from any chemical splashes.
- A garden hose with a high-pressure nozzle.

Choosing the Right Cleaner
For oil stains, a degreaser is essential. While oven cleaners can be effective, they are very strong and can damage the concrete if not used correctly. It's important to choose a cleaner that is safe for concrete surfaces. There are commercial degreasers available that are specifically designed for this purpose.

Application of the Cleaner
Apply the cleaner to the stained area generously. Make sure to follow the manufacturer's instructions regarding the amount to use and the safety precautions.

Let It Work
Allow the cleaner to sit on the stain for the recommended time, usually between 5 to 10 minutes. This gives the cleaner time to break down the oil.

Scrubbing
After the cleaner has had time to work, scrub the area vigorously with your stiff bristle brush or scrubbing pad. This step is crucial as it helps to lift the oil from the concrete.

Rinsing
Rinse the area thoroughly with your garden hose using the highest pressure setting. This will help to remove the cleaner and any loosened oil.

Repeat if Necessary
If the stain is particularly stubborn, you may need to repeat the process. It's important not to rush this process, as patience can lead to better results.

Sealing the Concrete
Once the stain is removed, consider sealing the concrete to prevent future stains. A concrete sealer can provide a protective layer that makes cleaning easier in the future.

Safety Note
Always remember to use cleaning products in a well-ventilated area and follow all safety instructions on the product labels.

Now, let's move on to the translation of the above guide into Chinese.
