Leather Balm is a type of conditioner used on leather products to restore and/or preserve its appearance. It is often used as a way to keep leather smooth and supple, and also helps to make it waterproof. This product typically works best on very smooth surfaces. In many cases, leather balm not only conditions leather, it also cleans it.
Typical ingredients include waxes, oils and lanolin, all of which are 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 discoloration. Dark leather normally does not get lighter as a result of the use of any balm, but could 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 is very deep.
