How do I remove stains from my Audi A2's interior carpet?

I recently spilled coffee on the carpet of my Audi A2 and now there's a noticeable stain. What is the best way to remove this stain without damaging the interior of my car?

First, try using a combination of baking soda and vinegar to gently scrub the stain. If that doesn't work, you can also try using a specialized car carpet cleaner. Make sure to test it on a small, inconspicuous area first to ensure it doesn't discolor the carpet.

If the stain is particularly stubborn, you may need to hire a professional detailing service to remove it. They have specialized equipment and products that can tackle tough stains without damaging the interior.
