how long can i keep squirty cream??

[cheeryface]

bought and used some of that cream that you squirt out a week or so ago. it's still in the fridge. can i use it or does it go off?

Ew you've just reminded me that it was something my mum used to keep in the cupboard for yonks. She'd just wipe the mould off and swore it would be fine.

We're all still alive.
