A lot of wood is dishwasher safe. But you should ask / check before hand. If it is made a several pieces glued together, it will probably not be. For cookware with PTFE non-stick coating, it is basically the only solution, with silicone, but I personally don't like silicone utensil. In any case, I also started to avoid PTFE coated cookware, because no matter how well you treat them, the coating will eventually get damaged (and PTFE is supposedly not very good for you). Now I just use stainless steel for anything that is not too sticky, and carbon steel for everything that need a bit of a non-stick surface to be cooked properly. They are not too hard to maintain and they don't get damaged like PTFE non-stick pan.
