Yarn and decorative bowls may need oiling and/or other care from time to time. Note, however, that most oils may change the color of the wood. The wood may have also changed colors from the original, due to aging and sun exposure. You can try using a light coat of clear mineral oil, leave it on for 20 minutes, then wipe off the excess. If your product is finished with a top coat of lacquer, you probably won't need to do anything. Lacquer builds up a film on the surface, keeping the original oil inside the wood surface.Any food-safe product can generally be refinished by using salad bowl finish, even if it's not a salad bowl. Drinkware most likely will have been finished with beeswax, which can be reapplied every few years by melting some wax and spreading it around the food containment areas. NOTE: Please do not put hot liquids/foods in areas lined with beeswax!!We are working hard to come up with care instructions for each product, so bear with us!
