To prolong the original appearance of your ethnicraft teak outdoor furniture and prevent the formation of stains, we recommend regular application of Outdoor Teak Protector from the very first use. If you prefer the gray patina that wood takes on when exposed to the elements, simply rinse your furniture in water and clean with Outdoor Teak Cleaner before use. Ethnicraft Outdoor Teak Protector can be applied at any time to maintain the desired color for longer. Environmentally-friendly, water-based formula.
