Clean the peeling area with a sponge dipped in warm soapy water. This removes any dirt or debris and prepares the sofa for fixing.
Dry the area thoroughly with a dry towel.
Dip a nylon scrub pad into the warm soapy water and lightly scrub the area in circular motions. This scuffs the sofa, which helps the dye to stick. Dry the area again with the towel.
Pour denatured alcohol onto a paper towel, and wipe down the peeling area. Ensure the whole area is covered, and allow to dry naturally.
Dip sandpaper into the soapy water and wet-sand the peeling area. Remove any debris with the sponge, and dry with a towel.
Spray the leather preparation spray onto the area and rub in. Check your leather preparation spray for instructions before you use, as some do not need to be washed off. Pat the sofa dry using a paper towel.
Spray the leather dye onto the area. Spray a light layer, and allow to dry, either naturally or using a hair dryer. Once completely dry, apply another light layer. This ensures the dye cannot be detected from the color of the sofa, and will look natural.
Allow the couch to dry for at least 8 hours before sitting on the sofa.
