What's the best way to clean muddy carpets in my Nissan X-Trail?

I recently took my X-Trail on a muddy off-roading trip and now my carpets are covered in dirt and mud. What's the best way to clean them without damaging the upholstery?

You can try using a mixture of water and vinegar to spot clean the muddy areas. Then, use a mild detergent and water solution to clean the entire carpet. Remember to blot, not rub, to avoid damaging the fabric.
