Nubuck / Roughout Leather Care

01. Clean

Use the Eraser Bar from the Roughout/Nubuck Cleaner Kit on soiled area of footwear. If stain persists, wet Eraser Bar and repeat. Allow leather to dry and use the Bristle Brush to restore the leather's nap.

02. Condition

Lightly apply Mink Oil to Muleskinner Leather. Mink Oil will darken leather and should only be used sparingly. Allow the leather to dry. All other Roughout and Nubuck leathers do not require conditioning.

03. Protect

Lightly mist footwear with Leather Protector six to eight inches away from the leather in a sweeping motion. Leather Protector provides a shield against dirt and moisture. It will not darken footwear.
