I had to throw them away. They absorb oil and fat from food and then leak over time no matter how carefully you clean them. Pulling these things out of the closet is an exercise in disgust. "Hey, remember that roast we made in August? Well, the fat from that grilled meat is everything on this silicone grill. Regardless of how clean they are at the end of the cleaning cycle, the drying cycle will cause the secret grease/grease/oil to escape and burn the odor into everything in the dishwasher, including the inside of the dishwasher itself. Surprise! Nothing is clean. Not even close. They get two stars for doing what they have to do while in the oven. The food rises above the surface of the pan. And if you're never going to use it as a stand, you can use it as a stand and I believe it will work just fine. But after several attempts to clean up these hellish things, I gave up. They go in the trash. sorry dump. I'm sure the silicone will degrade over time. Right? Just take metal racks. These things are just a terrible idea.
