  • Ski and surfboard wax remover
    Patent number: 4659498
    Abstract: There is provided an improved wax removing composition especially useful for removing wax from the top surface of surfboards, and a method of removing was utilizing the composition. The composition consists essentially of a major amount of a terpene hydrocarbon, and minor amounts of one or more fatty acids, e.g., tall oil acids, and rosin. A wetting agent, e.g., triethanolamine may also be included to aid in removal of the wax--solution from the surface after application. The principal advantages are that the composition provides a nonpetroleum product useful to replace beach sand as the means for wax removal and enabling water clean up without leaving a residue.
