I have been having moisture problems in my keezer. I took everything out, dried it completely and put an eva dry 500 in it. I still had moisture forming a day later so I put silicone on all my joints from the outside(they were previously sealed from the inside. I still have moisture after doing that. My EVA DRY is still blue. So it would seem it is not removing moisture. Do I have to do something to activate it? I didn't see anything in the instructions. Any suggestions?
