Bartoline Teak Oil is suitable for replacing the natural sheen that wood can lose after long periods drying in the sun. This is a popular wood treatment to replace natural oils removed by weathering. Bartoline Teak Oil can be used internally or externally on unpolished wood surfaces and is especially suited for use on wooden garden furniture. Bartoline Teak Oil contains a solvent carrier to aid penetration of the oil into hardwoods such as Oak and Teak.
