Agree with ladies who don't do anything or were told by Chanel to just take it in. I do nothing and send my bag in to Chanel every few years for clean and condition.
Chanel said don't overclean. They said When you rub, you also rubbing off color and leather, no matter how gently. It will take time to even notice, but nevertheless, you are wearing it down. Like over washing clothes... You are wearing it down as this is leather, an animal skin.
And don't constantly put product or chemicals on it. Chanel repair told me if you see any dirt, wipe with a damp soft cloth with water, then wipe dry. Don't wet the cloth, it just needs to be damp. Then take it in every few years. I have been taking this advice for years. I don't use any product and only clean when needed. Chanel was very clear to me not to overclean.
Doing nothing but a wet damp cloth wipe only when dusty Works great for me. I then sen in to chanel for professional cleaning and treatment. i posted this photo in another thread, but in case anyone is interested, this is my medallion I bought in March 2003. It's 10 years old. Never used anything on it and only sent it in to Chanel to let them professionally manage.
