For instance - miscellaneous toys and plastic items that you don't know are BPA free / dishwasher safe.
May have flipped out at DH for putting garden pegs in the dishwasher for the 1,000th time in spite of asking him not to. They are cheap, nasty plastic things and definitely not BPA free. MIL now thinks we need to ditch the baby bottles that were washed in the dishwasher in the same load though, in case the chemicals from the pegs have leached onto it?!
I will probably just rewash them and hope DH finally listens, but got me wondering, how strict are you about what does/ doesn't go in? Any bizarre things you or family members wash in the dishwasher, or are you strictly "dishwasher safe symbol only"?
