I brought my bag to the Chanel Store in SF and they tried to remove the coffee stains (someone knocked over whilst I was getting off the subway). I have also treated it with Apple conditioner but it's not working! The coffee stains is less visible now but you can still see the streaks! The more I try to clean it, the more wrinkles my lambskin gets. So I am trying to avoid too much rubbing causing the leather to cringe up like some raisin. Any suggestions???
