Diswasher safe ; Oven safe to 450 degrees.
All ovens vary. If your freshie isn't cooking all the way through, lower the temperature and add more time. Low and slow generally works better for silicone molds.
Other things to try:
-start from a cold over
-bake on a baker's rack instead of a cookie sheet.
If you can't get the scent out after a strong fredshie, try baking at 350 degrees for an hour, and then dunk it in vinegar.
Don't try to take a hot freshie out of the mold. Let it cool just like a cookie cutter. If you take it out hot, it could lose its shape.
