Tikis: our preference for outdoor treatment is Sikkens, it will last at least 2-3 years before you need to re-apply. Most of our monkey pod tikis are coated with it, if you need to check before your purchase, please call us to make sure.
Otherwise our go to product to shine your wood carving is Orange Oil from Howard.
Koa products: we use a triple 0 steel wool soaked with Orange Oil (to avoid scratching) and in circular motion. Then wip it down with a dry cloth.
Outdoor tikis: please make sure your tiki sits on some kind of concrete or stone base to prevent any type of damage. If your carving is standing up on the ground like grass or dirt the moisture will rot the base overtime.
For any additional questions or advice, please contact us. Aloha!
