Folks,
Simple stated, how does one go about performing this?

Do you just wipe off the excess dirt and recoat with lube? Or is a brush better and if so, how "hard" of a brush is typically used? Do you use a "cleaner" to remove all dirt/grime and then relube? If so, are their specific cleaners that anyone can recommend?
Please advise. Any advice would be greatly helpful! Thanks all!
