Using detailing brushes can be an effective way to clean various parts of your car’s interior, including carpets, air-conditioners, textiles, and leather seats. Here are some general steps to follow:

1. Choose the right brush: There are different types of detailing brushes available, and you should choose the right one for the surface you want to clean. For example, a stiff-bristled brush may be appropriate for carpets, while a softer brush may be better for leather seats.

2. Pre-clean the surface: Before you start using the detailing brush, it’s a good idea to pre-clean the surface with a vacuum or a cloth to remove any loose dirt or debris.

3. Use the brush to agitate the surface: Once you’ve pre-cleaned the surface, use the detailing brush to agitate the surface. For example, you can use a stiff-bristled brush to scrub the carpet fibers, or a soft-bristled brush to gently scrub leather seats.

4. Use a cleaning solution: To help loosen dirt and grime, you can use a cleaning solution that’s appropriate for the surface you’re cleaning. Apply the solution to the surface, and then use the detailing brush to work it in.

5. Wipe away excess solution: After you’ve scrubbed the surface with the detailing brush, use a clean cloth to wipe away any excess cleaning solution.

6. Rinse and dry: Finally, rinse the surface with water if necessary, and then dry it thoroughly with a clean cloth or towel.

By following these steps, you should be able to use detailing brushes effectively to clean your car’s interior. Just remember to choose the right brush for the surface you’re cleaning, and use the appropriate cleaning solution to get the best results.
