Using excel that was in storage for 2 years
I have read this before but just want to confirm, is it fine to use excel that is 2 years old? I left it in storage so light or temperature is not a factor. When I opened it, it was sealed tightly and it smelled fine with the excel not being dark brown.
^Does this have any affect on the effectiveness of it? I plan on just using it for pps pro to prevent molding.
Thanks
