i personally havnt done it (will be doing the oven method when i get around to it, my DDE's are sitting here) but i have heard that it takes SEVERAL hours. i would recommend doing the oven method. i think its like 20 minutes at 200 degrees or something?? (dont take me on that, search and find out).
i cant give you first hand, but i can tell you what people have told me.
