Thincat, hmmmm. I know that once I use the containers I don't air dry them out. I just close the lids and then they sit in my garage. I wonder if any remaining water turns acidic. I know there is residue inside the large garbage bin and this bin stays open to the air in the garage. In am just trying to make a corallation here.
