Waste water cap removal
2018 22' Bambi Sport FB that we bought and towed from Scotsdale, AZ to our home in NH. It was winterized for the trip in January, as we were traveling north through sub-zero weather. I have been familiarizing myself with everything for our maiden voyage next week. I find that I have trouble getting the waste water cap off. I don't like tapping plastic with a hammer, but that has been the only way to remove it. So, my question is, is there a lube or a wrench of some kind to make this easier, but still secure when putting it back on.
