Leather car seats require proper care to maintain their luxurious look and feel. Here are some tips on how to clean leather car seats:

1. Remove debris: Before cleaning, remove any debris from the seats using a vacuum cleaner or a soft-bristled brush.

2. Choose a cleaning solution: Do not use bleach or ammonia-based cleaners as they can damage the leather. You can use a commercial leather cleaner, or you can make your own by mixing warm water and Castile soap or liquid dishwashing soap together in a bucket. Use a ratio of 5 parts water to 1 part soap. Dampen a cloth with the solution and wipe down the seat surfaces. Another DIY idea to clean leather is to mix 1/2 cup of olive oil with 1/4 cup of vinegar in a spray bottle. Spritz on the seat, let sit for five minutes and wipe.

3. Spot cleaning: For stubborn stains, you can use rubbing alcohol or vinegar. Soak a cotton ball or tip of a washcloth in a 50% concentration of isopropyl or ethyl alcohol. Rub the stain gently, then wipe with a clean cloth. Vinegar has antibacterial properties and will not cause any damage to your seats. Simply spray on the part of the seat that you wish to clean, and wipe away with a clean, dry cloth.

4. Conditioning: Once your seats are clean, apply a leather conditioner that contains sunscreen to keep them from cracking and fading. Conditioner also makes the leather resistant to future stains and gives it a nice shine.

5. Prevention: The best way to keep leather car seats clean is to prevent stains. Wipe up spills as soon as they hit the seat. You can also use seat covers to protect the leather from spills and stains.

Remember to always test any cleaning solution on a small, inconspicuous area of the seat before applying it to the entire seat.
