I've tried searching the forum and can't see this topic discussed. My friend just bought me a blue oval plastic bobbin holder....it STINKS! (I have a softer round one that doesn't) I set it outside for 2 days, I sprayed it with fabreeze, I soaked it all day & overnight in vinegar....but this morning it still smells...I've just popped it into the freezer to see what happens..... other than throwing it away, does anyone have another idea that might help, thanks.
