When leather isn't conditioned, it dries out and starts to crack, peel, and change color. However, WD-40 can condition leather by adding moisture back into it, giving it new life.

Vacuum your leather furniture to remove debris, and wipe it down with a mild leather cleaning solution and a cloth. Afterwards, dry the surface with a fresh microfiber cloth.

Do a spot test on the bottom corner of your furniture, and check for discoloration once the WD-40 is absorbed and dry. If it looks fine, continue using it on the whole piece.

A simple can of the WD-40 Multi-Use Product can do the job, but you will need a white microfiber cloth, as colorful ones transfer their hues to leather.

Spray a thin layer of WD-40 and massage it into the leather with the cloth. However, be careful not to use too much product, as it can clog the leather's pores and make it sticky.

The WD-40 will soften the leather and leave a protective layer on top. That way, your furniture will be less likely to absorb oils and dirt as you use it and won't stain as easily.
