Clean the area you wish to dye. Dampen a clean cloth with warm water and mild soap. Rub the area in small circles to remove any surface stains, dirt or grime. Skip to step 3 if you do not have a leather recliner.
Saturate a clean rag with leather deglazer. Rub the deglazing agent into the same area, as final preparation for dying. Deglazer removes glazing elements to allow the dye to absorb into the leather. Follow deglazer label instructions. Purchase deglazer at any leather furniture store.
Coat the area with an appropriate color dye. Dab a foam brush into the dye. Swab the area with dye in one direction. Allow 90 minutes for the dye to dry before applying a second coat. Purchase a foam brush at any craft store.
