I've tried to google for an answer, but it's hard because mold has two meanings and in this case I'm using both. Some dessert got left in a silicone mold (shaping device) in the back of the fridge, and when I discovered it the dessert had gotten moldy (fungal growth). I washed the silicone as well as I could with soap and water, but it's still discolored. Is it possible to clean it enough to be food safe or do I need to throw it away?
If it is possible to clean it, what is the best way?
