The chances of removing wax stains on leather depend entirely on the type of the leather. Porous aniline, suede and nubuck are more difficult to treat, because the wax sinks into the surface. Coloured waxes can also cause problems, as the containing dye may colour the leather too.
DRIED WAX ON THE LEATHER SURFACE
Wax hardens when it gets cold. The colder the wax on a leather surface, the easier it is to remove it. If possible, use compressed air to blow the wax stains off. The compressed air cools down the wax and the air pressure blows the stains away. Especially with suede and nubuck, this is the ideal method. You can also roll smooth leathers to flake off wax residues. If you don’t have access to compressed air, cool down the stains with cooling elements from the freezer. Wrap a dry cloth around to absorb condensation humidity. Try to remove the wax by splintering and flaking off. It also helps to roll the leather by holding it between your thumb and your index finger. On pigmented leathers (wax remains on the colour coating) residues of wax can be removed by using a cloth to wipe away with a hair dryer to melt the wax. This method doesn’t work on absorbent leathers. Stains can even increase.
