I have used Pecard leather care on my leather holsters which helps to perserve the leather. I suggest that you use it sparingly and wipe it off after a few hours. After the application, brush the leather with a shoe brush and wipe the leather with a lint free cloth. I have heard comments that Pecard might darken light leather, however, I have not observed this change in any of my holsters.
Pecard is like a grease or fat and very mild on leather. Typically, I use it once a year or less depending if the leather shows any sign of drynes.
