To prolong the original finish of your Ethnicraft teak outdoor item and prevent stains, use Outdoor Teak Protector regularly from the outset of use. If the grey patina look that comes with natural weathering is preferred, simply rinse down furniture and clean using Outdoor Teak Cleaner before use. Ethnicraft Outdoor Teak Protector can always be applied at any point to prolong the desired wood colour. Water-based and eco-safe.
