Gentlemen, I need some help with cleaning my shoes. There is definitely a build up of wax that I am trying to remove using Lexol cleaner. The cleaner certainly takes a lot of elbow grease to work and below is how far i've gotten on one shoe. Notice the wax wearing away around the broging. It took me maybe 30 minutes just to remove that. Should it be taking that long? Would Renomat work faster? Any help would be mostly appreciated.
