I have a moen faucet handle that has been hard to turn and I suspect some kind of build-up. Anyway, I tried to remove the handle, and from my research, it seems I have to turn the base but it is really hard to turn. I tried WD-40 and a strap wrench but couldn't get it to turn and don't want to scratch it.
I figured I might have to remove the base altogether but I am still puzzled about how to take this out and don't want to start dismantling anything I can't put back together. There is no visible screw anywhere on the model. I have attached pictures below. How do I unturn this to clean the handle/base of the handle?
