Hand wash carefully. The porcelain is thin and can chip or crack if accidentally hit against something hard, like a faucet. We've never had problems putting our porcelain in the dishwasher, but if you have a particularly high powered machine, be wary of pieces knocking one another.
Dry clean or gentle hand wash. To remove folds, steam or steam iron on wool setting with a barrier. Knit materials can get caught on small things like jewelry. Gently pull loose loops back into place.
Wash with warm water and soap before use. This silicone is dishwasher and food safe; it is recommended to use the top rack. The oil is a natural quality of the material, is safe, and should wash off after a few uses. Be mindful that it can stain fabric, paper, wood, or any other material that absorbs oil. As with all silicones, it can be stained by intense color compounds (red wine, tomato sauce, coffee). These stains can typically be removed by soaking the area in 3% Hydrogen Peroxide for a few hours. Over long periods of time and heavy bending/use it is possible that the silicone will crack. Do not exceed 400° F or expose to direct flame. Make sure candles are secure before lighting.
Hand wash with warm water and soap before use. Yellowing is a natural process in silicone that is typically concealed by colorants in manufacturing. The process is sped up by exposure to light, heat, and mineral-rich water. We think it's beautiful.
Metals can be polished with an appropriate polishing cloth for the metal (silver, gold).
