   I use a 5% solution of KOH (for Brashear silvering) from time to time,   
   frequently enough so that I don't want to make it up every time, but not   
   so frequently that a bottle gets used up fast.   
      
   My problem is what to store it in. Glass is out of the question, as is   
   PET. PP maybe, but does CO2 diffuse through it?   
      
      
   Any suggestions?
