Leather Rejuvenator can handle anything from a dusty rusty barn find to a vehicle whose interior hasn't ever been graced with a speck of maintenance. This product is 100-percent conditioner with no cleaning properties. Generally 5- to 10-year-old leather would be a leading candidate for Leather Rejuvenator. It is highly concentrated, protects against future wear, and includes a fresh, new-leather scent. Best if applied with our Blue Detail Sponge.
