A soft bristle brush and dish soap. Fill a bucket with mild soap and warm water. Use the brush to gently scrub with the grain, then rinse with fresh water and allow to dry in open air. If your teak requires deeper cleaning, soak it in water or use a stiffer brush. If your teak was neglected for years, you can sand it down with 220 sandpaper. You can even use an electric palm sander if needed. Our products are made of 100% teak, no veneer or laminate – surface imperfections can be sanded away without fear.
