If you haven’t used it for awhile and it is stuck on, you have to muscle it. A man with big hands ( sorry feminists) and fingers should be able to do it easily. I am a medium build man y with skinny fingers. Undo the latch, place the tips of your fingers under the edge of the lip and pull like crazy. It hurt so bad that I used a dish wash cloth. I put my left arm around the pitcher, gripped it, gritted my teeth, told the lid that it would lose and I pulled it right off. Suggestion: don’ t store with the lid all the way down.
