Cleaning silicone

Cleaning silicone

Hi All, I made pumpkin bread and used silicone bake molds. The bread turned out great, but I can't get the silicone bakeware clean. I've soaked them in hot hot water, soaked them in hot hot soapy water, used a scrubber, a brush, a towel, picked at them with my fingers... The tops are still sticky and the crevices are stubborn. It doesn't help that the molds are shaped like leaves and pumpkins. So, any ideas on how to clean these up? Thank you so much, Happy Thanksgiving!!!
