Our teak furniture have suffered on our balcony in the sun already 1-2 summer. They cried to the right care, the original rich color they had lost. We cleaned the furniture at first like on the instructions described with a soap solution and let them dry. A day later we had a the teak furniture to the center in teak color. First, on the bottom, as we were put off by the color in the tin, a dark purple, but lo and behold, it was so, as we have liked. Are super protected from moisture and I think in the future you have to repeat it every 2-3 years.
