I have Ceramic leather interior that has a lot denim transfer staining on the drivers seat. I tried using Optimum Leather Conditioner/Cleaner but it would not remove all the blue stains. So today I stopped by a local detail supply store and asked if they had anything that would do the job. The clerk grabbed a bottle of CG Leather Cleaner and a microfiber towel and said lets go try this. It got off the majority of the stains using just the MF towel so I bought a bottle and along with a brush that he said would do a better job. Have to say it works great, removed all the denim stains.Thinking of picking up some Chemical Guys Leather cleaner and conditioner, but wanted to see what others recomend.
