weird film on silicone utensils

I bought a couple of silicone spatula/stirrers, and I'm plagued by an inability to clean them properly. Tossing them in the dishwasher gets off all of the obvious gunk, but I'm left with a greasy film, as well as a persistent odor of detergent. I've tried hand-washing, and it yields the same results. You can get rid of the dull, greasy film if you agressively scrub, then vigorously dry with a rough towel, but I find that these tools seem to retain the scent of the detergent. Has anyone else experienced this? I do realize that a microscopic film of "stuff" probably remains on all of my non-metal utensils, but the wooden spoons don't seem to give off that "Dawn" odor like the silicone.

  1. Sorry, I don't have any solution to your issue.

    I've noticed with the silicone ice cube trays we have that the trays seem to impart an unpleasant odor to the ice. I've tried coating the receptacles with cooking oil but it didn't help. They say that silicone is completely safe but I have to wonder because of the odor issue. There are other agents aside from the silicon and oxygen that are used as filler in its production.

    1. Most of what you describe is normal for silicone tools. There is nothing strange about what you observed.

      1. I agree with Chemicalkinetics. Although I haven't noticed the odor problem you describe, my silicone utensils always have a kind of strange "greasy" feel to them even when they are perfectly clean.

        1. I've bought a few silicone utensils and stopped using them specifically because of this problem. Tried different soaps, baking soda, vinegar, freezing ... everything. No success. Finally ended up throwing them out, or actually donating them to charity.

          1. I've noticed this too. I have a silicone muffin pan that I've used to make small quiches in, and it's become very nasty indeed. It seems to be uncleanable; despite my best efforts...sticky and horrid.

            At this stage I'm still using silicone spatulas, but that's about it.

              Oh thank goodness! I've noticed an off-taste to things I've made in my silicon muffin tins for a while...it wasn't noticeable with things like cupcakes...but the Yorkshire puddings taste and smell peculiar. I thought it was detergent ...but repeated clear-water scrubbing didn't help. My husband kept insisting that I was imagining things.I am tremendously relieved that other 'hounds have also noticed the phenomenon. Does anybody have a suggestion to alleviate the problem, or are these stupid things going into the trash? (I do like the way stuff pops right out of them, but not at the expense of good taste!)
