pb&j taste like soap So I got some scented dish washer soap the other day and my wife used it the first time the other day in the dish washer including by sandwich container. Today when I eat my pb&amp;j she made it tasted like scented soap. Do you think this is from left over water/soap or from it being scented soap?
It seems likely that there was some form of residue left behind in the container; whether this was actual soap or just the scent is difficult to determine.  I have found that soap scents do tend to cling a bit more stubbornly to plastic than they do to other materials, but that's just my experience.

Next time you might try rinsing the container and drying it out with a clean towel after washing.

Alternatively, you might simply discontinue using this particular soap.  It may be particularly clingy or perhaps you're just sensitive to its scent.
