I recently inherited a nice set of Tupperware measuring cups -- you know, those yellow/green/orange sets that were sold in the 70s and 80s? I really like them except for one thing: they all look a bit, um, grimy. I've tried washing them, scrubbing them, etc, but to no avail.
Does anyone have any suggestions? I'd soak them in bleach if I wasn't worried that they'd dissolve! :lol:
