Bartoline Teak Oil is formulated to replace the sheen hardwood can lose after long periods of weathering. Suitable for use either inside or out, and easy to apply with a cloth or brush. Teak Oil gives wood a natural sheen that lasts. Contains a solvent carrier to aid penetration into hardwoods such as Oak and Teak. A handy ready-to-use trigger spray is also available, this avoids the necessity of applying by brush or cloth.
