Silicon cake cases giving soapy taste to cakes- help!

[FaintlyMacabre]

My silicon muffin cases have acquired a taste of (I think) dishwasher powder, probably from our old dishwasher which didn't rinse properly. They give cakes a rather unpleasant soapy taste. This is persisting despite thorough hand washing and rinsing. Is there anything else I can try, or do they have to go?

Thanks.

I have this problem with all silicone, hand or dishwasher washed. I have been given loads of it as I bake a lot but it is sitting unused in the cupboard because I worry if I can taste it then so will everyone else. DH just thinks I am imagining things. I also have the problem with silicone spatulas and icing tasting soapy.

I've had a few silicon baking items and never had that happen! Silicon is so unreactive that I'd be inclined to suspect it was something else (flour/sugar contaminated with dishwasher powder maybe)?

I think I'd try making up a batch of plain sponge mix and baking half in the silicon cases and half in a normal tin, just to check it's not the ingredients you're using. If it is definitely the silicon cases, maybe immerse them in boiling water for half an hour and then scrub thoroughly again (oh, and replace the washing sponge you're using in case that has been impregnated with dishwashing powder).

If none of that helps then I'd get rid of them! Fortunately silicon muffin cases are reasonably priced these days :) HTH
