I've got some new Tupperware straight from where ever it's made. Should I wash it before I use it? Biggest thing I'm wondering about is the Popsicle makers..
Manufacturers often use chemicals such as 'mold release' (a light oil) to keep items from sticking doing production. Plus items are often handled by workers.
Washing new items before use gets rid of all those contaminates.
Yes I suggest washing it just as a precaution.
