How long do dairy filled eclairs last in the fridge?

2–3 days after opening.

Can you freeze dairy filled eclairs, and for how long?

Yes. 3 months from the date of purchase.

Throw it out if it smells off, feels slimy or sticky, shows mold, or has changed color. Storage times assume it was handled safely and kept cold the whole time.
