Leather items can easily become worn and cracked. Sometimes, this look might be desirable. However, there are some types of leather items that probably look better when they look fresh and new and are completely free of cracks, such as upholstery or car seats. If your leather has suffered from the wear and tear of cracks, professional repair is the best option. But in a pinch, there is a method that you can use to repair the leather cracks yourself and restore the appearance of your leather.
Clean the cracked leather with warm water and a few drops of mild dish detergent. Use this cleaning solution and a scrub brush to clean the leather. Dry with a terry cloth.
Wet a course scrubbing pad with the soap solution and scrub the leather again in tight circular motions. Dry with a terry cloth.
Saturate a paper towel with denatured alcohol and scrub the leather again. Dry it immediately with another paper towel.
Dip 240-grit sandpaper in the cleaning solution and scrub the leather yet again. The dye within the leather will lift. Move the dye into the cracks to fill them. Buff with a dry towel periodically and continue scrubbing with wet sandpaper until the cracks look better. Dry with a hairdryer to set.
Cover all areas of the leather that you have not scrubbed with pieces of cardboard or old towels. Then, spray the affected area with leather dye that matches the colour of the leather, keeping the spray about 1 foot away. Use a thin layer of dye. Allow it to dry and add another layer until the colour matches the rest of the leather. Speed up the drying process with the hairdryer.
Dry the leather completely and then add one coat of leather dye to the entire area. This helps blend the colour.
