What are the most effective ways to clean and maintain leather seats in an Audi A3?

I recently purchased an Audi A3 with leather seats and I want to make sure I am properly cleaning and maintaining them to prevent any damage. My previous car had cloth seats, so I am not very familiar with the best practices for leather. Any advice would be greatly appreciated!

Using a leather cleaner and conditioner specifically designed for automotive use is key. I recommend Meguiar's Gold Class Leather & Vinyl Cleaner and Conditioner. Apply it with a soft cloth and gently rub in circular motions, then wipe off excess with a clean cloth.
