For Stubborn Spots and Stains: Vacuum to remove loose soil. Use a mild solution of soap and water. Apply the solution to a clean wet sponge and wash, then rinse well. Let air dry naturally. Always try the cleaning method in a hidden area first to be sure of the results. Clean the entire area where the spill occurred.
For Butter, Oil or Grease: Wipe excess oil off the leather with a clean, dry cloth, and then leave it alone as the spot should dissipate into the leather in a short period of time. Do not apply water to clean these spots. Do not use: Hair dryers, any Saddle soaps, oils, abrasives, cleaners, furniture polish, varnish or ammonia water. The leather has already been permanently preserved in the tanning process and needs no maintenance other than the simple cleaning recommended.
