Our teak furniture comes with no finish at all. It is given a thorough glass polishing that leaves it very smooth and totally natural in colour. For everyday care this teak can be cleaned with a mild solution of soap & water. Frequent washing with the soap solution will increase the surface resistance. Of course if you would like to deepen the colour you can use teak oil -follow the directions carefully. There are commercial stain absorbing powders to remove stubborn oil, grease & fat stains. Just put some powder on the stain and leave for a few hours. Any residue should be removed using a fine sand paper. Always sand in the direction of the grain.
