You can radically mitigate the issue by using a secondary container for that which you'll use in a week or so, and only open the quart/gallon to dispense to working container.
 

 
I have dry argon in my shack to purge gas space in any container that is hygroscopic or oxidizes in presence of atmosphere.
 

 
I use 99.9 for cleaning all boards (flush after "scrub").    Where allowed, I follow up with RODI water flush and forced air drying.
