As the title says, I went to switch out my DI resin this past weekend and I cannot remove the lid from the container. Since the local water from the tap is pretty good, I can usually get about 9-10 months easily out of the resin. However, now the lid is stuck. I tried using the container wrench, but the screws start to bend the plastic frame and I'm afraid it's going to crack. I also tried removing the screws and soaking the lid under hot water. Any suggestions are welcomed. Thanks.
