Leather balm is a type of conditioner used on leather to either restore or preserve its appearance. It is often used as a way to keep leather smooth and supple, and it can also help to make it waterproof. This product typically works best on very smooth surfaces. In many cases leather balm not only conditions leather, it can also be used to clean it.
Typical ingredients include waxes, oils and lanolin, all of which are able to be absorbed by leather. It is possible, though, that using a balm can cause a light leather to become darker, so it should be used with care to avoid causing discoloration. Dark leather normally does not get lighter as a result of the use of any balm, but will only get darker.
Footwear made of various types of leathers is prone to being scuffed or dirtied in the course of normal use. Applying leather balm can help to protect the leather from damage. In many cases, it can also remove dirt and scratches from the surface of the leather, provided that none of the scratches goes very deep.
